Week 1 Tuesday - Last 4 km of the marathon

After finding out that they will all participate in a 42 km full marathon in three months' time, the contestants ran the last 4 km of the marathon. They ran the race in couples. The results were as follows:

• 1st place: Rick & Joe (37 mins)
• 2nd place: David & Phil (38 mins)
• 3rd place: Jenni & Phoebe (41 mins)
• 4th place: Allan & Romi (42 mins)
• 5th place: Jarna & Lisa (44 mins)
• 6th place: Elise & Teneale (45 mins)
• 7th place: Caitlin & Daina (1 hour 11 mins)
• 8th place: Wayne & Geoff (1 hour 16 mins)
• 9th place: Chris & Shannon (1 hour 54 mins) [Shannon only made it to the 1 km mark, but this was a great achievement for him.]

Week 1 Thursday - Housewarming Gift

Upon moving into Camp Biggest Loser, one couple was to find an extra special housewarming gift: the Double and Nothing bracelets. This couple had the power to choose who would get each bracelet. Allan & Romi found the bracelets in their room. They chose to give the Nothing bracelet to Shannon to protect him, and chose to keep the Double bracelet for Allan as they felt they couldn't make another contestant a target by giving it to them.

Week 2 Tuesday - Beachside Challenge

At Palm Beach, the contestants competed in couples for immunity. The couple first had to dig up a rowboat that was buried in the sand beneath them. They then had to carry the boat 200m to the other side of the beach, pick up a pair of oars tied together, and untie the oars. One person from the couple then had to row 500m out to a pontoon, collect their team's flag and row back to the beach. Finally, the couple had to run the 200m back to the start and plant their flag on the finish line. Due to medical issues, Geoff and Shannon were unable to compete, so their partners Wayne and Chris opted to compete solo (rather than sit out). Rick & Joe quickly dug out a boat and were off to a good start. They ran to the other side, rowed out, got their flag and ran to the finish line all before any other team had even managed to dig up a boat. Chris couldn't find a boat and Wayne offered to work together with him. Wayne and Chris got a boat out, and took it to the other side. They agreed that Wayne would row out first to get his flag, and then Chris would row out and get his flag, and then they would finish together. Wayne retrieved his flag, but on the way back one of his oars snapped. Wayne left Chris on the beach without a functioning boat and took his flag to the finish line. David & Phil were close behind Wayne and Chris, but Phil was unable to properly steer his boat, veering further and further off course, eventually having to be rescued by a motorboat. Jarna & Lisa arrived at the rowing side of the beach and Lisa rowed to retrieve their flag. The final results were:

• 1st place: Rick & Joe
• 2nd place: Wayne
• 3rd place: Jarna & Lisa
• Did not finish: Chris, David & Phil, Caitlin & Daina, Jenni & Phoebe, Elise & Teneale

Week 2 Thursday - Public Speaking

The contestants dressed up and were taken to the Riverside Theatre. They were told that they were each going to be given 5 minutes to speak on their own in front of an audience consisting mainly of past applicants for The Biggest Loser. Many of the contestants were afraid of the task but they all overcame their fears and shared with the audience their personal journeys, struggles and dreams.

Week 3 Tuesday - Secret Service

This was the contestants' first Temptation. The prize was immunity. The contestants were seated at tables in booths, separated from each other's view by curtains. Each table had a bell. The Temptation took place over the course of several rounds. Each round, a waiter came with a dessert. The number of calories in the dessert increased each round. After Hayley said "Who's tempted?", whoever rang their bell first would have to eat the dessert. Whichever contestant had consumed the most calories after the final round would win immunity for themselves and their partner. If no one played Temptation, immunity would stay with the previous week's immunity holders, Rick & Joe. The desserts that came out and the contestants that ate them were:

• Mini-lamington (65 Cal or 270 kJ): Daina
• Chocolate-coated strawberry (100 Cal or 420 kJ): Wayne
• Strawberry cupcake (137 Cal or 570 kJ): Daina
• Slice of sticky date pudding (274 Cal or 1,150 kJ): Daina
• Caramel slice (376 Cal or 1,570 kJ): Daina
• Carrot cake (762 Cal or 3,190 kJ): Daina
• Crème brûlée (2,498 Cal or 10,450 kJ): Daina

Daina nearly couldn't finish the last dish, and if she didn't she would forfeit all the calories she had eaten, but she managed to finish eating, winning immunity for herself and Caitlin.

Week 3 Thursday - Commando Challenge

The Commando surprised the contestants in the middle of the night, waking them up at midnight. He took them to a construction area. Instead of competing against each other, every member had to work together to do certain tasks by The Commando. The first task was for them to pull a heavy construction vehicle from one end of the area to the other, working as a team. The next task was to move 40 tonnes of crushed rock from one pile to another 15m away. During the task, The Commando revealed that at the bottom of the rock pile was something they all wanted, but they had to get to it before 6am. They managed to reach it and opened a box to reveal a key. Upon returning to Camp Biggest Loser, the key opened a package containing letters from home.

Week 4 Tuesday - Brains and Brawn

As couples, one member (the Quiz Master/Brains) was to answer a series of multiple-choice questions about food, diet and exercise. The other member (the Bucket Holder/Brawn) had to hold a rope that was suspending a bucket of water in the air via a pulley. Each couple got to choose which of them would play which role. For each question answered wrong, five litres of water would be added to the couple's bucket. The winner is the last couple still holding their bucket in the air. In the end, it came down to Rick & Joe and Caitlin & Daina. When Rick & Joe's bucket contained 50 litres, it was too much for them to hold onto and as a result, Caitlin & Daina won the challenge and immunity for the week. The couples were eliminated in the following order:

• 1st out: Chris (Brawn) & Shannon (Brains) - after 7 questions, carrying 30L
• 2nd out: Elise (Brains) & Teneale (Brawn) - after 7 questions, carrying 25L
• 3rd out: Wayne (Brawn) & Phoebe (Brains) - after 8 questions, carrying 25L
• 4th out: Jarna (Brawn) & Lisa (Brains) - after 10 questions, carrying 30L
• 5th out: David (Brains) & Phil (Brawn) - after 11 questions, carrying 40L
• 6th out: Joe (Brawn) & Rick (Brains) - after 14 questions, carrying 50L
• Winners: Caitlin (Brawn) & Daina (Brains) - carrying 30L

Week 4 Thursday - 10 km run

The contestants had been training to do a 10 km run, but didn't know exactly when it would be. On the day, Shannan and Michelle surprised the contestants by saying that the day had arrived. Whoever came first would win three phone calls, either to use themselves or give to another contestant. Unlike the 4 km run, the contestants ran this race as individuals. Due to injuries, Lisa, Shannon and David were unable to run the race. The results were as follows:

• 1st place: Wayne (1 hour 11 mins 45 secs)
• 2nd place: Daina (1 hour 14 mins 59 secs)
• 3rd place: Chris (1 hour 17 mins 12 secs)
• 4th place: Phil (1 hour 17 mins 46 secs)
• 5th place: Joe (1 hour 23 mins 16 secs)
• 6th place: Rick (1 hour 24 mins 35 secs)
• 7th place: Jarna (1 hour 25 mins 17 secs)
• 8th place: Phoebe (1 hour 30 mins 26 secs)
• 9th place: Teneale (1 hour 38 mins 36 secs)
• 10th place: Elise (1 hour 40-something mins)
• 11th place: Caitlin (1 hour 55 mins 7 secs)

As the winner, Wayne won the three phone calls. He chose to give them all away: one to Shannon, one to Lisa, and one to Phil.

Week 5 Tuesday - Mexican Standoff

In this Temptation, two couples stood over a barrel with a maraca. A plate of Mexican food was placed on the barrel. Once the 60-second timer was started, whoever grabbed the maraca first had to eat the plate of food, and so did their partner. If no-one grabbed the maraca, the couple originally at the barrel won the round without having to eat the food. The winners of the round then chose the couple to challenge next. Whichever couple won the last round would win the prize of Temptation, which was the power to choose which couple would be pitted against the other five couples for the next week. As winners of the previous week's immunity challenge (Brains and Brawn), Caitlin & Daina started as the first couple at the barrel and chose their first challengers.

• Round 1: Caitlin & Daina challenged Chris & Shannon. Caitlin & Daina figured that Chris & Shannon may have been tempted, and if they took it they would have to continue eating for the rest of the rounds. The dish was a beef enchilada worth 265 calories (1,110 kJ). No-one took the maraca. Caitlin & Daina won without eating.
• Round 2: Caitlin & Daina challenged Jarna & Lisa. They wanted to challenge the non-Firm members first. The dish was a chicken burrito worth 432 calories (1,810 kJ). No-one took the maraca. Caitlin & Daina won without eating.
• Round 3: Caitlin & Daina challenged David & Phil. The dish was five chilli chocolates worth 569 calories (2,380 kJ). No-one took the maraca. Caitlin & Daina won without eating.
• Round 4: Caitlin & Daina challenged Rick & Joe. The dish was nachos worth 745 calories (3,120 kJ). No-one took the maraca. Caitlin & Daina won without eating.
• Round 5: Caitlin & Daina challenged Wayne & Phoebe. The dish was a capirotada worth 1,265 calories (5,290 kJ). Despite being a part of the Firm alliance, Wayne surprised Caitlin & Daina by taking the maraca, forcing himself and Phoebe to eat the food on the plate. they each had a plate of capirotada to eat. Wayne finished it, but Phoebe wasn't able to finish hers, and as a result, Wayne and Phoebe didn't win the round.

Caitlin and Daina won Temptation without eating anything and decided they would be the couple to face off against the other five couples. For the remainder of the week, it was "all vs one" where Caitlin and Daina's percentage weight loss had to be greater than the other five couples' average percentage weight loss to win the weigh-in. Caitlin & Daina chose their trainer for the week and picked Michelle, leaving the others with Shannan. Should Caitlin and Daina win the weigh-in, they will decide which of the other contestants to eliminate. Otherwise, the five couples will decide who between Caitlin or Daina will be eliminated.

Week 5 Thursday - Mini-Carnival

The challenge this week was one couple vs. five - Caitlin & Daina vs. the rest, due to the results of Temptation. They were playing for a 2 kg weight advantage at the next weigh-in, which would also be Caitlin & Daina vs. the rest (according to average percentage weight loss). The challenge consisted of five events in a mini-carnival format, testing their knowledge, agility, speed, strength and stamina. As the lone couple, Caitlin & Daina chose which of them would compete, and which of the other contestants they would compete against. For each event, they had to choose a competitor from a different couple. The first team to win three out of the five events would win the challenge.

• Event 1 - Speed: Daina competed against Jarna. The event was a 100 m sprint. Daina won.
• Event 2 - Strength: Caitlin competed against Phoebe. The event was a tug of war. The competitors stood on platforms holding a rope between them. Each competitor had to pull the other off their platform. The event was best out of three, so the first to win two rounds would win the event. Caitlin won two rounds back-to-back by getting Phoebe off-balance and then loosening the rope, making Phoebe fall off her platform.
• Event 3 - Agility: Daina competed against Phil. The competitors stood inside a circle with a rotating beam machine. The machine had two beams sticking out from it, one at about shoulder height and the other at shin height. The machine rotated the beams clockwise, starting slowly but increasing in speed over time. The competitors had to duck under and jump over the beams as they passed, without stepping out of the circle. A competitor would lose a round if they broke one of the beams or stepped outside of the circle. After one competitor lost three times, the other would be the winner. Phil broke one beam by stepping on it. In the second round, Daina clipped a beam without breaking it, but Phil thought Daina had broken it and so stepped out of the circle, losing the round. In the third round, Phil again stepped on a beam and broke it, so Daina won the event.

There was no need to run the last two events, as Caitlin & Daina had already won three events out of the five. Caitlin & Daina won the 2 kg advantage at the next weigh-in.

Week 6 Tuesday - Survival of the Fittest

In this challenge, the contestants had to navigate a mud obstacle course to reach a pile of car tyres. They could then collect one or two tyres to carry back through the obstacle course and place on poles assigned to their rivals. They could then go back and continue to fetch tyres. Once a contestant's poles carried 30 tyres (10 tyres on each of 3 poles), they were eliminated from the challenge. The last competitor remaining won the challenge and the prize of immunity. Shannon and David were unable to compete due to injury. The contestants were eliminated in the following order: Chris (30 tyres), Lisa (retired due to back injury), Daina (retired due to thumb injury), Caitlin (retired due to ankle injury), Joe (30 tyres), Jarna (30 tyres), Phoebe (30 tyres), Rick (30 tyres). After 4 hours, Phil was the last contestant remaining and won immunity.

Week 6 Thursday - Everyone Has Their Price

The contestants were given a Temptation to leave the game (including forfeiting participation in the second-chance marathon) for a certain amount of money (to be taken out of the amount set aside for the winner of the competition). The money was offered to each contestant one after the other, in increasing order of the contestants' total percentage of weigh-loss at that time since the beginning of the game. Jarna (who had the lowest total percentage of weight-loss) was offered $1,000, which she declined. The money was increased to $5,000 and offered to Shannon, which he also declined. The money was then offered to Phoebe and again increased, this time to $10,000; she also declined. The money was then offered to Chris and increased to $15,000. He accepted the money stating he can now get his life back on track after money problems due to him losing his job. Chris now has no way of returning to the game, as he will not be allowed to compete in the marathon.

Week 7 Tuesday - Wheel of Temptation

Temptation consisted of several rounds of spinning one of three wheels to win a prize. The most important prize on the wheels was immunity, and along with immunity the winner would receive power to pair off the other eight contestants to go head-to-head for the rest of the week. This would culminate at the weigh-in, where the contestant from each pair with the lower percentage weight loss would be below the yellow line (so there would be four contestants below the yellow line). Apart from immunity, there were other prizes on the wheels worth a total of $50,000. To obtain a spin of a wheel, the contestant would have to eat a chocolate item, with the number of calories getting greater as chances of winning increased. The order of contestants being offered a spin was determined by numbered discs the contestants were standing on.

• 1st wheel: There was a 1 in 33 chance of winning immunity, and a 10 in 33 chance of winning another prize (10 prizes with a combined value of over $5,000). The admission fee for a spin of this wheel was to eat a small chocolate worth 77 calories (320 kJ).
  1. Shannon: Declined to play.
  2. Joe: Played. Won nothing.
  3. Jarna: Played. Won nothing.
  4. Phil: Played. Won nothing.
  5. Phoebe: Declined to play.
  6. Rick: Played. Won nothing.
  7. Caitlin: Played. Won nothing.
  8. Lisa: Declined to play.
  9. David: Played. Won an Avanti dumbbell package worth $199.
• 2nd wheel: There was a 1 in 16 chance of winning immunity, and a 7 in 16 chance of winning another prize ( prizes with a combined value of over $30,000). The admission fee for a spin of this wheel was to eat five profiteroles worth 500 calories (2,100 kJ).
  1. Shannon: Declined to play.
  2. Joe: Declined to play.
  3. Jarna: Declined to play.
  4. Phil: Played. Won nothing.
  5. Phoebe: Declined to play.
  6. Rick: Played. Won nothing.
  7. Caitlin: Declined to play.
  8. Lisa: Declined to play.
  9. David: Played. Won a 3-night adventure package for two people with flights and accommodation to Queenstown, New Zealand.
• 3rd wheel: There was a 1 in 4 chance of winning immunity, and a 1 in 2 chance of winning another prize (the two prizes were an 8-day tour of China for two people including airfares worth over $7,000 and two VIP tickets to the Australian Formula 1 Grand Prix including flights and accommodation worth $8,000). The admission fee for a spin of this wheel was to eat a chocolate mousse worth 1,000 calories (4,200 kJ).
  1. Shannon: Declined to play.
  2. Joe: Declined to play.
  3. Jarna: Declined to play.
  4. Phil: Played. Won the tour of China.
  5. Phoebe: Declined to play.
  6. Rick: Played. Won nothing.
  7. Caitlin: Declined to play.
  8. Lisa: Declined to play.
  9. David: Played. Won nothing.
• Final round: Since immunity had not been won in the first three rounds, contestants were offered another spin on the third wheel at the cost of eating another chocolate mousse (1,000 calories or 4,200 kilojoules). As the China tour prize had been won, its slot was replaced by a free spin. This time, the order of offers was determined by Hayley pulling names out of a bag.
  1. Shannon: Declined to play.
  2. David: Played. Won immunity.

As the winner of immunity, David paired off the other contestants to go head-to-head at the next weigh-in: Lisa and Jarna, Shannon and Phoebe, Joe and Phil, Caitlin and Rick.

Week 7 Thursday - Head to Head

The contestants were taken to the State Sports Centre at Sydney Olympic Park for this week's challenge. Following on from the week's theme of pitting pairs of contestants against each other in a head-to-head battle, the challenge involved the head-to-head pairs competing in exercise activities. The four losers of the activity challenges would be denied access to the gym, equipment and trainers for the rest of the week until the weigh-in. As the holder of immunity, David did not have to compete.

1. Shannon vs. Phoebe (10-minute gym cardio): Whoever did the most reps in 10 minutes won the challenge. Shannon did 656 reps, defeating Phoebe who did 589 reps.
2. Rick vs. Caitlin (spin bikes): Whoever clocked the higher number of kilometres in 10 minutes won the challenge. Rick clocked 8.6 km, defeating Caitlin at 7.4 km.
3. Phil vs. Joe (treadmills): The contestants ran on the treadmills, starting at 5 km/h and increasing their speed by 1 km/h at every minute mark. Whoever lasted the longest won the challenge. Joe forfeited when they were running at 14 km/h (after the 9-minute mark), making Phil the winner.
4. Lisa vs. Jarna (rowing machines): The contestant that rowed 2.5 km first won. Lisa defeated Jarna.

As a result, Phoebe, Caitlin, Joe and Jarna lost access to the gym, equipment and trainers for Last-Chance Training.

Week 8 Tuesday - Balance and Concentration

In this challenge, the contestants all stood on a long platform made up of seven poles positioned in the middle of a swimming pool. Poles were stripped away from the platform one after the other at random times, making the platform narrower and narrower as time went on. Whichever contestant was the last one still standing on the platform would win immunity. Rick and Joe tried to unsettle the other contestants by wobbling the platform, and there was trash talking between the contestants trying to get each other to lose balance. At 20 minutes in and after three of the seven poles had fallen, Phil lost his balance due to Rick's wobbling and fell off. Shortly afterwards, Lisa lost her balance too. She grabbed Rick to try to stabilise herself but Rick fell and grabbed Lisa to take her with him. At 42 minutes in, another pole fell, the remaining contestants tried to shake each other off, and David fell. At 1 hour 33 minutes in, Shannon lost his balance and fell off. This sent a shockwave through the platform, causing Caitlin to lose her balance and fall off. Caitlin's fall in turn made Joe lose his balance and fall, leaving Phoebe as the last one standing and the winner of immunity.

Week 8 Wednesday - Half-Marathon

This challenge was aired on a Wednesday instead of a Thursday. The day of the 21 km half-marathon arrived, and the contestants were taken to a national park for the race. Hayley said that the winner of the race would be presented with a unique opportunity, but did not say what it was. David was unable to run the race at all due to medical conditions. Shannon was only able to run 200m, Lisa was only able to go for half an hour, and Rick was only able to run 7 km and then walk the rest of the way. The results were as follows:

• 1st place: Phil (2 hours 24 mins 18 secs)
• 2nd place: Joe (2 hours 35 mins 20 secs)
• 3rd place: Rick (2 hours 56 mins 56 secs)
• 4th place: Phoebe (3 hour 15 mins 42 secs)
• 5th place: Caitlin (4 hour 16 mins 4 secs)

Lisa was able to cover close to 3 km in the half an hour she was able to race. As the winner, Phil was to be presented with a unique opportunity. It was to be a challenge of sorts, but before he was told what the opportunity was, Phil had to choose another contestant to confront the challenge with him. Phil chose to take Joe with him. It was then revealed that the two of them would be taken by The Commando to train for the next five weeks in a secret location. Whichever of the two of them had lost the higher total percentage weight loss since week 1 would return to the competition as one of the final 4. The following episode (Thursday) focused on Phil and Joe's first day of training with The Commando in the Northern Territory.

Week 9 Tuesday

There was no challenge on this day as the episode instead focused on the contestants receiving total body makeovers from Joh Bailey.

Week 9 Thursday - Food Heaven

In this week's Temptation, the contestants each had a turn in a room filled with all kinds of different foods, each labelled with the number of calories in them. Each contestant could eat as much food as they wanted, and did not know how much the other contestants ate. Whichever contestant ate the highest number of calories would win immunity, or if none of the contestants ate, immunity would remain with Phoebe, the holder of immunity from the previous week. The contestants went into the room in the following order:

1. Phoebe: Ate chocolates (98 Cal or 410 kJ), lollies (70 Cal or 290 kJ), strawberries and cream (106 Cal or 440 kJ), and more chocolates (98 Cal or 410 kJ), for a total of 372 calories (1,560 kJ).
2. David: Did not eat anything.
3. Lisa: Did not eat anything.
4. Rick: Ate a sausage roll (517 Cal or 2,160 kJ), hot chips (392 Cal or 1,640 kJ), a hamburger (545 Cal or 2,280 kJ), tomato sauce (14 Cal or 59 kJ), cola (129 Cal or 540 kJ), a doughnut (305 Cal or 1,280 kJ), a lamington (244 Cal or 1,020 kJ), a creaming soda (100 Cal or 420 kJ), and another hamburger (545 Cal or 2,280 kJ), for a total of 2,791 calories (11,680 kJ).
5. Shannon: Did not eat anything.

Rick won immunity, having consumed 2,791 calories (11,680 kJ).

Week 10 Tuesday - Abseiling

For their first challenge in New Zealand, the contestants had to abseil down Kitekite Falls, drops of 18, 4 and 48 metres (totalling 70 metres). They were led by Shannan and Michelle and encouraged to leave their old selves at the top of the falls and embrace their new life at the bottom of the falls.

Week 10 Wednesday - Personal Challenge

The contestants were in New Zealand, and there was an extra challenge for the contestants this week. Aboard the R. Tucker Thompson in the Bay of Islands, each contestant was set a personal challenge by Shannan and Michelle to face their deepest fears. Michelle challenged Phoebe and Lisa to climb to the top of the rigging, then climb halfway down and jump over the side of the ship. Shannan challenged David and Shannon to swim underneath the ship from one side to the other.

Week 10 Thursday - Treasure Hunt

The contestants were set another challenge by Shannan and Michelle. At the end of the challenge was a treasure that they had 30 minutes to find in order to receive it. Starting on a beach, each contestant swam out to a kayak, dove down to unclip it from its anchor, and then climbed in and paddled 400m to the beach on the other side of the water. There they found a tiki with their name on it, indicating the location at which they were to dig to find their treasure. David found his treasure chest first after 15 minutes, then Lisa found hers after 19 minutes, Phoebe found hers after 24 minutes and Shannon found his after 27 minutes. The treasure chests contained items from home for each of the contestants. David's chest contained his karate black belt (with extension), a charm from his wife's charm bracelet that he gave to her, a card from his two children, and some family photos. Lisa's chest contained a card from her daughter Chelsea, and a shirt belonging to her husband Campbell. Phoebe's chest contained some photos, and a letter from her mum. Shannon's chest contained a gold chain that he used to wear but stopped wearing because it didn't fit his neck, his old football jersey that he hadn't worn since he was 17, and a letter from his fiancée Sarah.

Week 11 Wednesday - Flag Raising

This challenge was aired on a Wednesday instead of a Tuesday, as the Tuesday episode instead focused on the contestants viewing a video of Phil and Joe training with The Commando in the Northern Territory. The prize in this challenge was immunity, but David was ineligible to compete as he had gained weight at the previous weigh-in. In this challenge, each contestant had to retrieve a winch handle from a flag pole, and then use it to raise the flag poles belonging to their opponents. Each contestant had 5 flag poles, and if all 5 of their flags were raised, they were out of the challenge. The last contestant remaining would win immunity. Flags were raised in the following order:

1. Shannon raised Lisa's 1st flag.
2. Phoebe raised Shannon's 1st flag.
3. Lisa raised Shannon's 2nd flag.
4. Phoebe raised Shannon's 3rd flag.
5. Shannon raised Lisa's 2nd flag.
6. Lisa raised Phoebe's 1st flag.
7. Shannon raised Lisa's 3rd flag.
8. Phoebe raised Lisa's 4th flag.
9. Shannon raised Phoebe's 2nd flag.
10. Lisa raised Phoebe's 3rd flag.
11. Phoebe raised Shannon's 4th flag.
12. Shannon raised Phoebe's 4th flag.
13. Lisa raised Phoebe's 5th flag. (Phoebe was eliminated while raising Lisa's 5th flag.)
14. Shannon raised Lisa's 5th flag (partially raised by Phoebe). (Lisa was eliminated while raising Shannon's 5th flag.)

Shannon won immunity with 4 flags raised.

Week 11 Thursday - Rochelle Gilmore's Spin Bike Challenge

In a special training session with cyclist Rochelle Gilmore, the contestants were challenged on their spin bikes. Each spin bike was hooked up to a car's headlights, with the headlights being turned on when the contestant cycled above a settable RPM level. At the end of the spin training session, Rochelle set a challenge for the contestants to maintain 130 rpm for 4 minutes. All four contestants hit 130 rpm. Lisa dropped out first, followed by Shannon. Phoebe and David were still going after 3 minutes, at which point Shannan raised the bar to 140 rpm for the last minute, which both Phoebe and David met. With 30 seconds remaining, Shannan raised the bar again to 150 rpm. David was able to reach 150 rpm, but Phoebe was not. David was able to last the set time and won the challenge. There was no prize for the challenge.

Week 12 Wednesday - Northern Territory Marathon

Tuesday's episode focused on the eliminated contestants returning to Camp Biggest Loser in preparation for the marathon. In the Wednesday episode, Phil and Joe undertook their own 42 km marathon in the Northern Territory, starting at 2am. For each of them that finished the race, $10,000 was donated by Vodafone Foundation to Red Dust Role Models. Phil finished first in 5 hours and 6 minutes. Joe finished in 6 hours and 17 minutes. As both of them made the distance, $20,000 was donated to Red Dust Role Models.

Week 12 Wednesday-Thursday - Eliminated Contestants' Marathon

All the eliminated contestants (except for Geoff and Chris) took part in the 42 km marathon, having trained for it for the past 11 weeks. Lisa and David were unable to participate due to injuries, but Shannon was allowed to walk 10 km. The first male and first female eliminated contestants to finish the race would return to the competition. The results were as follows:

• 1st place: Wayne (1st male, 5 hours 20 mins 35 secs)
• 2nd place: Daina (1st female, 5 hours 28 mins 31 secs)

• 10th place: Caitlin (7th female, 8 hours 4 mins 50 secs)
• Did not finish: Romi (retired after 23 km)

Shannon completed the 10 km he was allowed to walk. Wayne and Daina received black T-shirts and returned to the competition.

Week 13 Monday - Filling Cars with Apples

Instead of having a special guest trainer following Elimination, the contestants were set a challenge by Shannan and Michelle as a training session. The contestants were taken to Barangaroo, where they each had to carry a total of 3 cubic metres of apples using a wheelbarrow, buckets or sandbags and fill a small car with the apples. Lisa was not allowed to carry heavy loads, so her car was moved closer to the apples than the other contestants', and Shannon was not allowed to run. Wayne and Shannon took the lead at first. Shannon overtook Wayne but Lisa caught up to them. Lisa and Shannon took the lead, and Lisa ended up finishing first.

Week 13 Tuesday - Super Challenge

The contestants were taken to Katoomba for a super challenge. The winner of the super challenge would win the power to move one of the bracelets, potentially to themselves or away from themselves. In addition, the winner would win 5 nights for two at The Golden Door retreat in the Hunter Valley and $5,000 cash. The challenge consisted of two parts. In the first part, the four contestants were split up into two teams (allocated randomly by drawing coloured stones from a bag). Lisa and Shannon drew blue stones, so they were a team, and Daina and Wayne drew red stones, so they were the other team. For the first part of the challenge, one member from each team had to climb down a ladder hanging from the Scenic World Skyway, a cable car suspended 1,000 feet (300 m) above the ground, and retrieve a flag at the bottom of the ladder. The other team member had to support their teammate by rope from the cable car. The team that retrieved their flag first won the first part of the challenge and the chance to compete against each other in the second part of the challenge. Shannon was chosen to climb down the ladder as Lisa was unable to do so due to her foot injury, and Daina chose to climb down as Wayne had a fear of heights. Daina retrieved her flag first, so she and Wayne competed in the second part of the challenge. For the second part of the challenge, the contestants were taken to a table with 8 different foods: a tin of baked beans, 1 large hamburger bun, 50g of potato crisps, 1 Mars bar, 250 mL of full fat milk, small fries, a can of Coca-Cola, and a slice of cheese. In the best of three rounds, each contestant (Wayne and Daina) had to choose a different food, and whoever chose the food with the lower number of calories won the round. Wayne and Daina took turns being first to choose a food in a round. To choose who would choose first in the first round, they drew stones from a bag. Daina drew a stone without an X on it, so Wayne was allowed first choice in the first round.

• 1st round: Wayne went first and chose the slice of cheese (84 calories). Daina chose the tin of baked beans (112 calories). Wayne won the round.
• 2nd round: Daina went first and chose the potato crisps (255 calories). Wayne chose the milk (158 calories). Wayne won the round.

Wayne had won two rounds, so there was no need for a third round. Wayne won the super challenge, including the prizes of the holiday, the cash, and the power to move one of the bracelets. He chose to leave Lisa with her Double bracelet, and instead relieve Daina of the Nothing bracelet (giving it to Shannon) as reward for winning the first part of the challenge.

Week 13 Wednesday - Hanging In There

In the Northern Territory, The Commando set a challenge for Phil and Joe to hold onto vines of a banyan tree with their legs in an L-shaped sitting position, facing each other, until one of them dropped. It was a face-off between the two as they would soon be competing against each other for a spot back at Camp Biggest Loser. Phil dropped first, so Joe won the challenge.

Week 13 Thursday - Whitewater Rafting Team Challenge

The contestants were taken to the Penrith Whitewater rafting centre, where they took on the Olympic-grade course in two rafts. Lisa was unable to participate due to her injuries. There was a girls' raft (Daina, Michelle, and two female instructors) and a boys' raft (Shannon, Wayne, Shannan and a male instructor). After a couple of practice runs, the two rafts raced. Although the boys took the lead early, they hit a rock and spun around, allowing the girls to overtake them and win the race.

Week 13 Thursday - Whitewater Rafting Solo Challenge

After racing in team rafts, the three contestants took to the course individually in kayaks, with one instructor each to guide them. Shannon took the lead early but was thrown into a wall and capsized. Wayne overtook him but then Daina overtook Wayne. Daina won the race.

Summary

Masterclass Challenges

• Week 1: No Masterclass aired this week.
• Week 2: No Masterclass aired this week.
• Week 3: The challenge this week was a ten-minute workout. Each couple had a different exercise station, and had ten minutes to burn as many calories as possible. Whichever couple burnt the most calories (according to their heart-rate watches, and adjusted for their relative sizes) won the challenge. The couples picked their exercise stations out of a bag in the following order:
  • Caitlin & Daina: Punching bag (248 calories burnt, 5th place)
  • Elise & Teneale: Steps (226 calories burnt, 6th place)

  • Rick & Joe: Free weights (461 calories burnt, 1st place)
• Week 4: The challenge this week was to cook healthy alternatives to popular fast food dishes. After being allocated a dish, each couple had $15 and 15 minutes at the local supermarket to buy ingredients for their healthy alternative. They then returned and had 60 minutes to cook their meals, to be judged by Shannon, Michelle and Hayley. Each couple chose a fast food dish at random in the following order:
  • Caitlin & Daina: Fish & chips with mayonnaise sauce (alternative: pan-fried white basa with sweet potato & parsnip chips)

  • Chris & Shannon: Steak, baked potatoes, mushrooms & creamy sauce (alternative: rib-eye steak with mashed cauliflower and other vegetables)
  • Rick & Joe: Big breakfast with bacon, fried eggs, sausages & hash brown (alternative: egg-white omelette with chicken, capsicum, shallots & onion plus a side dish of garlic, mushrooms and grilled capsicum)
  • Elise & Teneale: Creamy pasta carbonara with bacon (alternative: wholemeal pasta with tomato-based sauce & chicken)
  • Jarna & Lisa: Family sized pizza (alternative: prawn & pine nut pizza with ham & low-fat ricotta cheese)
  • David & Phil: Roast chicken with skin on, roast vegetables & gravy (alternative: steamed chicken breast, no skin on, healthy vegetables)

  The winners as judged by Shannan, Michelle and Hayley were Rick & Joe. An extra mention was made for Wayne & Phoebe's hamburger, and the Coach's Encouragement Award from Shannan went to David & Phil (as it was Phil's first meal ever cooked).

• Week 5: The challenge this week was to create a gym workout out of items commonly found around the home. Each couple was allocated an area of the body to target with their workout, and a collection of household items. The couples had to design two exercises, using the items, that would work the muscles in their allocated area of the body. The workouts were judged by Shannan and Michelle based on creativity and effectiveness in working the target area. The couples picked their target areas out of a bag in the following order:
  • Wayne & Phoebe: Arms
  • Caitlin & Daina: Legs
  • Jarna & Lisa: Shoulders
  • Chris & Shannon: Dynamic core
  • David & Phil: Chest
  • Rick & Joe Back

  The couples had 15 minutes to design their exercises, which had to be safe, efficient and effective. The winners were Caitlin & Daina, who designed an agility cardio workout stepping in tyres, and a step workout.

• Week 6: The contestants had to cook breakfasts for a peloton of 30 cyclists. There were four tents, each with an ingredient that was to be the core of their breakfast: eggs, bread, pancakes, and oats. Teams were chosen by the contestants running to the tent of their choice, with a maximum of three contestants to a tent. The teams had a short time to decide what to cook, and then one member from each team had a minute to make a single trip to the table of ingredients to choose the rest of their ingredients. The teams then had half an hour to cook their meals. The cyclists then arrived and ate their choice of breakfasts, and then voted on their favourite meal. Whichever team received the most votes would win the challenge.
  • Eggs tent: (Joe and Caitlin): Scrambled eggs with onion, garlic, parsley, mushrooms, grilled capsicum and tomato.
  • Bread tent (Daina and Phil): 2 types of bruschetta (tomato, spinach, onion and balsamic vinegar; and mushrooms, ham, cottage cheese and parsley).
  • Pancakes tent (David, Rick and Phoebe): Banana wholemeal pancakes with sliced fruit, ricotta, lemon juice and lemon zest.
  • Oats tent (Lisa, Jarna and Shannon): Wet muesli with dried fried and yoghurt, toasted oat trifles layered with yoghurt and fresh fruit.

  The eggs tent came fourth with 4 votes, the oats and bread tents came equal second (unknown number of votes) and the pancakes tent won with 9 votes.

• Week 7: The contestants were taken to Fitness First, and worked in groups of three to design workout plans to allow someone to train despite having an injury. The groups each developed a minimum of three exercises to train while protecting the injured part of the body. They were to be judged by Shannon and the gym's physiotherapist Todd on how efficiently, effectively and safely their workout exercised their whole body without troubling their injury. They could use any part of the gym, and had 5 minutes to devise their workout plan and 10 minutes to demonstrate it. There were three teams, each having to work around having a particular injury:
  • Hamstring injury team (Lisa (leader), Shannon and Phil): lateral pulldowns & chest presses, grinder machine, and boxing.
  • Rotator cuff injury team (David (leader), Rick and Joe): cross trainers & crunches, leg presses & squats with medicine ball, quad & hamstring isolation exercises.
  • Ankle injury team (Caitlin (leader), Jarna and Phoebe): Their workout consisted of boxing & crunches, spin bikes at low resistance, and weights (lat pulldown, shoulder press, chest press, and row).

  The hamstring team had the safest workout, but they could have done more with exercising shoulders and arms. The rotator cuff team had a comprehensive workout but the medicine ball exercise was a little unsafe for a shoulder injury. The winners were the ankle team of Caitlin, Jarna and Phoebe.

• Week 8: The contestants cooked healthy lunches. They worked in pairs, each with a designated lunch option, and had 1 hour to make lunches to present to a gym circuit class of 20 people, who would then vote on their favourite lunch option, considering calories, nutritional value, presentation and flavour. Whichever pair received the most votes would win the challenge. The pairs were:
  • Caitlin and David (sandwiches): ham, egg & salad sandwiches, and roast beef & salsa sandwiches - 5 votes.
  • Lisa and Rick (wraps): chicken & avocado wraps, and char-grilled vegetable wraps - 10 votes.
  • Shannon and Phoebe (salads): Caesar salad, and tuna & chickpea salad - 5 votes.
• Week 9: There was no Masterclass challenge aired this week.
• Week 10: The contestants took part in the SkyJump, a jump off the Auckland Sky Tower from a height of 192m. This was not a normal Masterclass challenge for the Masterclass Champion's Shield, but rather a chance for the contestants to face their fears, similar to what they had been doing all week for their time in New Zealand. David, Lisa and Phoebe made the jump, but Shannon was unable to participate as he was over the weight limit. Shannan (the trainer) also jumped.
• Week 11: No Masterclass aired this week.
• Week 12: The contestants had to cook delicious affordable seafood meals for two, each using a different type of seafood. The contestants were given a $15 budget. Dishes were judged by Shannan, Michelle and Hayley based on nutrition, calories, taste, presentation and cost. The contestants had 10 minutes to shop for their ingredients and then 30 minutes to prepare and plate their meals.
  • Daina was assigned white fish (snapper, flathead, barramundi). She cooked a garlic- and herb-seasoned flathead fillet with a char-grilled vegetable salad for $9.39 per serve.
  • Lisa was assigned oily fish (mullet, salmon, sardines, mackerel). She cooked a rocket and roast vegetable salad with salmon and a dill, honey and lemon juice dressing for $8.08 per serve.
  • Wayne was assigned whole fish (snapper, flathead, whiting, bream). He cooked a whole snapper with tomato bocconcini for $9.08 per serve.
  • David was assigned seafood with legs (squid, octopus). He cooked a Thai-style calamari with salad and prawn toast for $10.25 per serve.
  • Shannon was assigned shellfish or crustaceans (mussels, oysters, prawns, crabs). He cooked a banana prawn, asparagus, snow pea and chili stir-fry for $7.03 per serve.

  The winner as judged by Shannan, Michelle and Hayley was Shannon.

• Week 13: The contestants each had to teach a class of gym regulars in a 30-minute workout in a particular activity. The activities they were assigned were:
  • Shannon: boxing
  • Daina: circuit training
  • Lisa: spinning
  • Phil: calisthenics
  • Wayne: AFL footy fitness
  • Joe: boot camp

  Each class was assigned a professional trainer to observe and report to Michelle, who made the final decision on the winner. Michelle awarded the win to Joe, who gave a class in which Michelle felt a desire to participate.

Note: The Masterclass Champion's Shield was seen up close in Week 13's Masterclass, showing the titles of all the Masterclass challenges up to and including Week 12 (excluding the SkyJump in Week 10). In addition to the challenges listed in the table above, there was an additional challenge entitled "Food Court Challenge", which was won by Jarna & Lisa. The label for this challenge was visible on the Shield during Week 3's Masterclass challenge, which suggests that a Masterclass challenge of this title was held in either Week 1 or 2 but was never aired (due to heavy re-editing of the first two weeks).
