VFL/AFL pre-season competition

The pre-season competition was established from the Australian Football Championships Night Series in 1988. The Night Series had been a competition featuring VFL, SANFL, WAFL and minor states representative teams which had been staged partly in the pre-season and partly during the premiership season, generally finishing in July; but, it had reduced in size and importance until 1987, when only VFL teams were involved and the competition was finished by the end of April. In 1988, the competition was moved entirely into the pre-season, and became the VFL Pre-season Cup. The pre-season competition is generally considered to be of equivalent importance as both the AFC Night Series and the VFL Night Series (1956–1971), and records relating to the three competitions are often combined.

Between 1988 and 1999, the competition was run as a simple knock-out tournament in which the winning teams moved through to the next round and losing teams were eliminated. Before there were sixteen teams in the AFL, the previous season's top-ranked teams (either the premier or both grand finalists) were advanced directly to the second round; after Fremantle entered the league as the 16th team in 1995, all teams began in the first round. In 1992, the competition introduced the Michael Tuck Medal for the best player in the grand final.

After criticism that the knock-out format limited the preparation of the losing teams, a round-robin format was introduced in 2000. The sixteen teams were split into groups of four, each playing three pool matches with the winner of each group advancing to the knockout semi-final stage. The public reaction to the change was mixed, as the atmosphere at some of the pool games was noticeably flat compared with previous years. The competition reverted to the straight knock-out format in 2003, and retained that format until 2010.

In 2011, the pre-season competition expanded to eighteen teams with the addition of the Gold Coast Suns (which joined the day premiership in 2011) and the Greater Western Sydney Giants (which joined the day premiership in 2012). Over the following three years, the first round of the pre-season competition was staged with six pools of three teams, with each group playing a round-robin of half-length lightning matches on the same day at the same venue. The format from that point was:

• In 2011, the winner of each of the six groups, and the two teams with the next-best records, advanced to an eight-team knock-out tournament of full-length games.
• In 2012 and 2013, all teams then played two pre-scheduled full-length games, giving each team a total of four matches (two lightning matches and two full-length matches). The teams with the best two records over the four matches then faced off in the Grand Final.

Since 2014, the competitive aspect of the preseason was abandoned altogether, and replaced with a series of discrete practice matches spanning a three-to-four-week period prior to the home-and-away season. This format features no ranking or overall winner. It does retain some of the experimental features of the former competition, including the super goal. Since 2021, the series has been known as the AAMI Community Series.

Most games during the pre-season competition, including the final, were night matches. Normal games were typically played slightly short of full-length (quarters lasting 17½ or 18 minutes plus time-on instead of the normal 20), and with an extended interchange bench of six or eight players to offer less physically demanding conditions for the pre-season games. Lightning matches, when they were played from 2011 until 2013, were played over two-halves of 20 minutes plus time-on. Extra time was played to resolve drawn knock-out games.

Since 2003, pre-season matches have featured the super goal as a scoring option. The super goal, which scores nine points, is awarded for a goal kicked from beyond the 50-metre arc.

Particularly in the 21st century, the pre-season competition was used to trial rule changes before they are introduced into the premiership season. Among the notable rule trials were:

2003

• Three points for a deliberate rushed behind.

2005

• After a behind is scored, no requirement to wait for the goal umpires to finish waving their flags before kicking out. (Has been introduced into the premiership season)
• A larger centre circle.
• Four field umpires
• Umpires coming in 10m from the boundary line to throw in the ball.
• Play on if the ball hits the goal post and bounces back into the field of play.

2006

• Play on called for backward kicks, except when that kick takes place within the attacking team's forward 50m.

2007

• Video replay umpire for goals. Ability for goal umpire decisions to be overruled by video umpire.
• All nine umpires able to pay free kicks (includes boundary and goal umpires) (Trialled only in Melbourne vs Hawthorn Round 1 NAB Cup 2007)
• Play on called for backward kicks, only in the defensive half of the field.
• Kick must travel 20m to be paid a mark.

2008

• Eight players on the interchange bench, only 16 interchanges permitted each quarter.
• 2.5m x 6.5m "no-go" area around the centre bounce, where players are prohibited before and during the bounce until the umpire clears the area.
• Centre bounces only at the start of a quarter and after goals, ball is thrown up otherwise. (Has been introduced into the premiership season)

2009

• If the ball is hand-passed or kicked for a rushed behind the opposition receives a free kick (Introduced into the premiership season in 2009 AFL season)

2010

• Players can determine if there is an advantage in play (has been introduced into the premiership season)

1990

Essendon vs Fitzroy (Feb.28) was the first VFL/AFL match to be decided using extra-time – the Bombers getting home by a goal in overtime then winning their next two matches to claim the title.

1993

Problems with new turf at Waverley Park forced the relocation of three matches – Melbourne v Collingwood (Feb.17) was moved to Princes Park, whilst Essendon v Brisbane (Feb.27) and Footscray v Fitzroy (Feb.28) were moved to Kardinia Park.

A record night series/pre-season Grand Final crowd of 75,533 fans saw Essendon defeat Richmond.

1997

The Grand Final was held at the MCG to capitalise on Grand Prix weekend in Melbourne, the first time it had been played away from Waverley Park. A near-record crowd of 74,786 watched Carlton defeat Geelong.

1998

Pre-season football was played outside Australia for the first time, with Brisbane defeating Fremantle in Cape Town, South Africa (Feb.22) followed by Melbourne defeating Sydney in Wellington, New Zealand (Mar.1).

2000

Carlton and Collingwood played the earliest pre-season match in history, with a one-off match called the "Millennium Challenge" played on the evening of 31 December 1999 at the MCG and counting towards the preseason competition. The game was sparsely attended.

2001

The final was played for the first time between two non-Victorian teams, and consequently the match was played outside Victoria, at Football Park in Adelaide.

2006

A new rule was introduced to determine the venue of the pre-season Grand Final. The team scoring the most goals in the first three rounds would host the title match. If two teams were tied after the semi-finals the number of super goals kicked would act as a tie-breaker.

Trophy

2007 NAB Cup trophy won by the Carlton Football Club

The design of the trophy for the pre-season competition has varied greatly over the years.

When it was the Wizard Home Loans Cup it was affectionately known by fans as the "Wizard Wok" due to the shape of it being like a wok.

More recently it has taken the more traditional trophy shape.

Although many clubs and coaches (especially the wealthier clubs) do not take the pre-season competition seriously and use the competition as a chance to test young and inexperienced players, the preseason competition proved reasonably popular with spectators. The competition's Grand Final could draw more than 60,000 spectators to the Melbourne Cricket Ground, and usually drew more than 40,000 to Docklands Stadium or Football Park (both of which had a capacity of around 55,000)
