Eligibility

Jack Watts, the first pick of the 2008 AFL Draft, was drafted at the age of 17. Effective from the next year, players must be at least 18 years of age on 31 December to be eligible to be drafted

From the 2009 draft, players must be at least 18 years of age on 31 December in the year in which they are drafted, so that players who turn 18 during their first months of Year 12 will be able to finish studying without the pressure of AFL. This was increased over the past few years due to concerns about school age players potentially having to leave home to play football interstate.^[3]

A selection of approximately 50 players are chosen to attend the annual AFL Draft Combine at the conclusion of the AFL season, prior to the National Draft. Further smaller scale state screenings are held around the country in the weeks after the national combine.

Priority draft pick rule

Travis Johnstone, the first pick of the 1997 AFL draft, was drafted with a priority draft pick

The priority draft picks were first introduced in the 1993 AFL Draft as a special assistance rule to aid teams that consistently perform poorly to obtain additional early draft selections.

Under the rules in place since the 2012 season, priority draft picks are given out to struggling teams at the discretion of the AFL Commission. This replaced a system in which a priority draft pick was automatically given to team whose win–loss record fell below a pre-defined value; this had become controversial, and there were accusations by commentators that teams out of finals contention would tank at the end of the season to gain access to the additional draft picks, although the AFL itself never brought such accusations against any club.^[4]

Zone Allocation rule

Northern Club Academies: GWS, Sydney, Gold Coast and Brisbane all have club-based academies that help develop talented athletes, sometimes from before they’re teenagers, into AFL prospects in markets where the code isn’t seen as the No. 1 sport. The four clubs have priority access to those players via a bidding system.

Next Generation Academies: Clubs outside of New South Wales and Queensland have established academies with players from multicultural and Indigenous backgrounds, meaning they have priority access to the players they’ve developed via a bidding system. Note: Clubs that have existing links to NGA players are now unable to match bids inside the top 40 selections on the prospects they’ve developed due to a recent AFL rule change.

Father–son rule

Dustin Fletcher, the son of Ken Fletcher has played the most games of any father-son selection, with 400 AFL matches played

To continue the traditions of association that a family has with a particular club, sons of former players are able to be selected by the same club as their father played with under the father–son rule.

For clubs with an established history in the VFL/AFL (20 years or more), the father must have played at least 100 games for the club to be eligible for the father/son rule; clubs with no long term history in the league had different eligibility criteria based on their state leagues.

Under current rules, players eligible under the father–son rule are selected in a bidding system prior to the draft. Firstly, any club in the league may nominate a draft pick with which it intends to take the eligible son; then, if the father's club wishes to draft the son, it must use its next available draft pick, after the highest bidder.^[5]

Earlier versions of the father–son rule allowed the sons to be recruited automatically, without need for the draft, or allowed the club to recruit the son using a third round draft pick. The father–son rule itself was introduced in 1949, more than three decades prior to the draft, and it could be used to contravene zoning rules.

AFL Women's: Father-daughter rule and future rules for AFL Women's players

Abbie McKay, the daughter of Andrew McKay, was the first player to be selected under the father-daughter rule

On 15 September 2016, an AFL women's competition, the AFLW, was founded to commence in 2017.

In its Draft, there is an equivalent father–daughter rule, where a daughter can be drafted if their father played one game at the club. The first use of this rule was in the 2017 Draft, when Carlton selected Abbie McKay, the daughter of Andrew McKay.^[6]

Criteria are also in place for mother–son and mother–daughter rules, from such time that the children of AFLW players reach draft eligible age.

Expansion clubs

Each time that the competition has an expansion team, the AFL give special priority to the new club, with the new club receiving numerous high draft picks.

Men's

As of 2021, the number one draft pick was taken by the last-placed team from the previous season, or an expansion team in its first draft, in 31 of the 38 drafts.

Years where this was not the case are:

• Where the number one pick has been traded, for example when Fremantle traded the number one pick of the 2001 AFL draft to Hawthorn for Trent Croad. Other trades took place in 1988, 1990, 1992 and 2022.
• In 1996, where West Coast were given the first draft pick for being the lowest-ranked team to have lost an uncontracted player (Ian Downsborough) to expansion team Port Adelaide: the team that finished last, Fitzroy, had its AFL playing operations taken over by Brisbane at the end of 1996.
• In 2002, where Carlton, who had finished last, lost their priority picks and their first and second round picks for salary cap breaches. St. Kilda, who had finished 15th of the 16 teams, received the first draft pick and selected Brendon Goddard.
• In 2007, where Carlton, who had finished 15th of the 16 teams, received the number one draft pick by virtue of the priority pick rules at the time. The team that finished last, Richmond, received the second overall pick and also received a priority pick at the end of the first round.

Despite the expectations of the number one pick, not all have forged successful VFL/AFL careers. Adam Cooney, the first pick of the 2003 AFL draft, was the first number one draft pick to be awarded the prestigious Brownlow Medal (in 2008), and remains the only first pick Brownlow Medallist to date. In the same year, Luke Hodge, the number one pick in 2001, won the Norm Smith Medal with Hawthorn, and remains the only first-pick Norm Smith Medallist to date. No number one selection has yet been inducted into the Australian Football Hall of Fame. Only four number one picks have won a premiership (Drew Banfield, Des Headland, Luke Hodge, and Tom Boyd).

The following is a list of the number one overall draft picks since the draft's inception in 1981:

Women's

Isabel Huntington, the first pick in the 2017 AFL Women's draft. Huntington is the first number-one draft pick to be selected for the AFL Women's All-Australian team, the first number-one draft pick to be selected for the AFL Women's 22 Under 22 team, and the first number-one draft pick to win the AFL Women's Rising Star award

With the introduction of a women's competition in 2016 (to commence in 2017), a draft was set up for the AFLW.

In 2016, the first draft pick was awarded to the GWS Giants by lot, though this selection would be taken after 16 selections were made for marquee players: Nicola Barr was the first player to be drafted in AFLW history.

In 2018, the first pick was awarded to Geelong as one of the expansion clubs for the 2019 season, and in 2022, the first pick awarded to Sydney as one of the expansion clubs for Season 7: in both years, this was determined by lot from the four expansion clubs.

As of 2022, five of the eight seasons have seen the first pick go to the club who finished last, or an expansion club in its first draft: in 2017, GWS traded the first pick to the Western Bulldogs; in 2019, expansion club Richmond traded the first pick to the Western Bulldogs; and in 2023 Sydney traded the first pick to Geelong in a once-off overage draft.

International rookies

Rookies are also available to be selected from overseas countries and players on the list do not count towards the salary cap. Notable examples are Irish Tommy Walsh of Sydney; Canadian Mike Pyke of Sydney, a former rugby union international; and Americans Seamus McNamara and Mason Cox, both former college basketball players who were rookie listed by Collingwood.

In 2006, the AFL introduced a new scheme where clubs can maintain two international rookies (excluding Irish players) outside of the regular rookie list.^[10]

The rule was adjusted in 2010 to group international rookies with players recruited from other sports, and refers to them as Category B rookies. Up to three can be listed in addition to up to six Category A rookies.^[11]
