A-League Men#Squad formation and salary cap

A national round-robin tournament existed in various forms prior to the formation of the A-League, with the most notable being the National Soccer League (NSL). The formation of the NSL came after Australia's qualification for the 1974 FIFA World Cup, which led to discussion of a national league, with 14 teams eventually chosen to participate in the inaugural season of the NSL in 1977.{{cite book | title=The World Game Downunder | publisher=Australian Society for Sports History | date=2006 |editor1=Hay, Roy |editor2=Murray, Bill | location=Melbourne | page=120 | isbn=0975761668}}

Under the guidance of the then-governing body, the Australian Soccer Federation (later Soccer Australia), the NSL flourished through the 1980s and early 1990s but then fell into decline with the increasing departure of Australian players to overseas leagues, a disastrous television deal with the Seven Network and the resulting lack of sponsorship.{{cite web | url=https://thefootballsack.com.au/2013/05/ch7-broadcast-football-prepare-your-fallout-shelter.html | title=Ch7 broadcast football: Prepare your fallout shelter | work=The Football Sack | date=24 May 2013 | access-date=3 November 2023 }}{{cite web | url=http://www.theroar.com.au/2011/04/19/a-brief-history-of-the-nsl-part-iv/ | title=A brief history of the NSL: Part IV | work=The Roar | date=19 April 2011 | access-date=9 April 2013 | archive-date=2 July 2018 | archive-url=https://web.archive.org/web/20180702122254/https://www.theroar.com.au/2011/04/19/a-brief-history-of-the-nsl-part-iv/ | url-status=live }} Few clubs continued to grow with Sydney Olympic, Perth Glory, and the newly established Adelaide United the exception in a dying league.{{cite web | url=http://www.sydneyolympicfc.com/history/origins | title=Origins | publisher=Sydney Olympic Football Club | access-date=9 April 2013 | archive-url=https://web.archive.org/web/20130419083514/http://www.sydneyolympicfc.com/history/origins | archive-date=19 April 2013 | url-status=dead}}{{cite web|url=http://www.footballaustralia.com.au/howe-opinion-display/History-against-the-Wanderers/61310 |title=History against the Wanderers |work=footballaustralia.com.au |publisher=Football Federation Australia |date=21 February 2013 |access-date=9 April 2013 |author=Howe, Andrew |url-status=dead |archive-url=https://web.archive.org/web/20140411063031/http://www.footballaustralia.com.au/howe-opinion-display/History-against-the-Wanderers/61310 |archive-date=11 April 2014 }}{{cite web | url=http://www.theroar.com.au/2013/02/25/wanderers-help-lay-some-ex-nsl-ghosts-to-rest/ | title=Wanderers help lay some ex-NSL ghosts to rest | work=The Roar | date=25 February 2013 | access-date=9 April 2013 | archive-date=2 July 2018 | archive-url=https://web.archive.org/web/20180702122311/https://www.theroar.com.au/2013/02/25/wanderers-help-lay-some-ex-nsl-ghosts-to-rest/ | url-status=live }}

By June, 20 submissions had been received and a month later 12 consortiums sent in their final bids for the eight spots.

The round is part of a partnership with Destination NSW, and was introduced after the Grand Final decision was reversed in October 2023, one year into its original 3-year stretch after severe fan backlash.{{cite web|url=https://www.abc.net.au/news/2023-10-18/a-leagues-scrap-controversial-grand-final-decision-introduce-mag/102989960|title=A-Leagues scrap controversial Grand Final decision in favour of Unite Round|website=ABC News|date=18 October 2023}}

After Adelaide United player Josh Cavallo became the first openly gay top-flight male footballer in October 2021, the A-League partnered with A-League Women to stage a single Pride men's and women's doubleheader during the 2021–22 season.{{cite web | last=Lynch | first=Joey | title=Australia's A-Leagues launch first Pride round | website=ESPN.com | date=7 February 2023 | url=https://www.espn.com.au/football/story/_/id/37636165/australia-leagues-stage-first-pride-round-february | access-date=7 March 2024}}

On 24–26 February 2023, both the A-League Men and Women's competitions staged their first-ever Pride Round, the first occasion in which the leagues had "come together to recognise and promote inclusion for the LGBTQIA+ community". Part proceeds from ticket sales across all of the round's fixtures were donated to Pride Cup. In 2024, the Australian Professional Leagues (APL) announced the continuation of the round, as well as providing inclusion training to all players and key stakeholders. The A-Leagues would be collaborating with the PFA and Pride Cup, who would help to deliver the training. The annual Pride Cup double-header between Adelaide United and Melbourne Victory would take place in March, and several men's and women's teams would celebrate by engaging community groups and using indicators such as rainbow corner flags, armbands, special Pride kit and/or rainbow socks.{{cite web | title=The 2024 A-Leagues Pride Celebration is this week: Everything you need to know | website=A-Leagues | date=3 March 2024 | url=https://aleagues.com.au/news/a-league-pride-celebration-fixtures-details-dates/ | access-date=7 March 2024}}

The top six clubs at the conclusion of the regular season progress to the finals series. The finals series culminates to the A-League grand final, where the winner is crowned A-League champion. The club that wins the grand final is presented with the A-League Champions Trophy.

The finals series consists of six teams who are placed by rank, as determined at the end of the regular season. The finals series runs over four weeks. In the first week of fixtures, the third-through-sixth ranked teams play a single-elimination match, with the two winners of those matches joining the first and second ranked teams in two-legged ties played over two weeks. The two winners of those matches meet in the grand final. This method was initially adopted for the 2021–22 season.{{cite web|url=https://www.a-league.com.au/news/extra-finals-adds-drama-202122-isuzu-ute-a-league-season|title=Extra finals adds to drama for 2021/22 Isuzu UTE A-League season|work=A-League|date=29 October 2021|access-date=30 October 2021|archive-date=30 October 2021|archive-url=https://web.archive.org/web/20211030023755/https://www.a-league.com.au/news/extra-finals-adds-drama-202122-isuzu-ute-a-league-season|url-status=live}}

Up until 2022, between the two grand finalists, the team that finished higher on the ladder at the conclusion of the regular season hosted the grand final. The only exception to this was if the FA deemed that team's home ground to be an inappropriate venue. For example, in 2008, Central Coast Mariners (as the higher-placed team) hosted the grand final against the Newcastle Jets at Sydney Football Stadium, due to FFA deciding that Central Coast Mariners' home stadium, Central Coast Stadium with a capacity of 20,000, was too small for the event.{{cite news | url=http://news.smh.com.au/sport/sfs-to-host-aleague-grand-final-20080212-1rrl.html | title=SFS to host A-League grand final | work=The Sydney Morning Herald | date=12 February 2008 | access-date=9 June 2013 | archive-url=https://web.archive.org/web/20131017184255/http://news.smh.com.au/sport/sfs-to-host-aleague-grand-final-20080212-1rrl.html | archive-date=17 October 2013 | url-status=dead}}

Most A-League Men clubs have teams in the A-League Youth competition, which runs in conjunction with the A-League Men as a national youth developmental and reserve league. All players in the youth teams are between the ages of 16 and 21 as of the start of the calendar year for each new season, while four over-age players from each of the senior teams also allowed to be selected. In addition, the A-League Women operates as the top division of women's league with affiliations to the men's competition.{{cite web|url=http://www.footballaustralia.com.au/InsideFFA/default.aspx?s=insideffa_newsfeatures_newsitem&id=22966 |title=Women in a league of their own |date=28 July 2008 |publisher=Football Federation Australia |url-status=dead |archive-url=https://web.archive.org/web/20131203151814/http://www.footballaustralia.com.au/InsideFFA/default.aspx?s=insideffa_newsfeatures_newsitem&id=22966 |archive-date=3 December 2013 }} However, the A-League Youth has not been resumed since the COVID-19 pandemic.

In response to the debate about the development of a new professional second division, the Australian Championship has been proposed to support the A-League, with the aim to avoid the American franchise-based system and to put in line with European football leagues.{{cite web|url=https://www.espn.com.au/football/australia-aus/story/4441281/football-australia-adds-national-second-tier-to-football-pyramid-in-calendar-restructure|title=Football Australia adds national second tier to football pyramid in calendar restructure|first=Joey|last=Lynch|publisher=ESPN|date=30 July 2021|access-date=24 September 2021|archive-date=24 September 2021|archive-url=https://web.archive.org/web/20210924162722/https://www.espn.com.au/football/australia-aus/story/4441281/football-australia-adds-national-second-tier-to-football-pyramid-in-calendar-restructure|url-status=live}}

{{Further|List of A-League Men clubs}}{{A-League 2024–2025 map}}

The league is currently contested by 13 teams: eleven from Australia and two from New Zealand. A total of 16 teams have competed at some stage in the league's short history. Only four of these clubs – Adelaide United, the Brisbane Roar (as the Queensland Lions), the Newcastle Jets, and the Perth Glory – existed before the A-League was formed in 2004. Gold Coast United, the New Zealand Knights, and the North Queensland Fury have formerly competed in the league.

Unlike most leagues from across the world, there is no system for relegation and promotion of teams. The A-Leagues system thus shares some franchising elements with most other professional leagues in Australia, Major League Soccer, Canadian Premier League, and other major Northern American-based sports leagues.

{{Main|Expansion of the A-League Men}}

While making a relatively modest start to ensure future stability, both the FFA and the soccer media indicated significant interest in expanding the league. The eight foundation clubs had exclusivity clauses for their respective cities valid for five years, but this did not exclude teams from other areas joining the league.

Before the introduction of the A-League, FFA chairman Frank Lowy speculated that he hoped to expand the league into other cities, mentioning Canberra, Hobart, Wollongong, Geelong, Bendigo, Cairns, Ballarat, Albury–Wodonga, Launceston, Christchurch, Auckland, Sunshine Coast and possibly Darwin and later Singapore.{{cite web | url=http://www.a-league.com.au/default.aspx?s=newsdisplay&id=601 | title=ASA announce several significant initiatives | publisher=Australian Soccer Association|date=22 March 2004 | archive-url=https://web.archive.org/web/20060909222618/http://a-league.com.au/default.aspx?s=newsdisplay&id=601 | archive-date=9 September 2006}}{{cite web | url=http://www.a-league.com.au/default.aspx?s=newsdisplay&id=629 | title=A-League launch speech by FFA chairman Mr Frank Lowy AC | date=13 November 2004 | publisher=Australian Soccer Association|archive-url=https://web.archive.org/web/20060912075020/http://www.a-league.com.au/default.aspx?s=newsdisplay&id=629 | archive-date=12 September 2006}}{{cite news|first=Paul |last=Osbourne |title=Chief talks up Townsville |url=http://www.foxsports.com.au/story/0,8659,20081770-5000940,00.html |work=Fox Sports |date=10 August 2006 |access-date=6 February 2007 |archive-url=https://web.archive.org/web/20070312010117/http://www.foxsports.com.au/story/0%2C8659%2C20081770-5000940%2C00.html |archive-date=12 March 2007 |url-status=live }}{{cite web | url=http://au.fourfourtwo.com/news/119653,gippsland%E2%80%99s-aleague-call.aspx | title=Gippsland's A-League Call | work=Australian FourFourTwo | date=4 January 2010 | access-date=22 December 2012 | last=Ormond | first=Aidan | archive-date=22 September 2012 | archive-url=https://web.archive.org/web/20120922144755/http://au.fourfourtwo.com/news/119653,gippsland%E2%80%99s-aleague-call.aspx | url-status=dead }}

There are several key rivalries and local derbies that have formed in the A-League, including:

"Melbourne Derby" – Melbourne City v Melbourne Victory

The two Melbourne clubs first met on 8 October 2010 in a lively game at AAMI Park in front of 25,897 fans. Melbourne City (known at the time as Melbourne Heart) came out on top with a 2–1 victory.{{cite web|url=http://www.melbourneheartfc.com.au/default.aspx?s=aleague_newsdisplay&id=35811|title=Heart Claim Inaugural Derby Win|date=8 October 2010|url-status=dead|archive-url=https://web.archive.org/web/20110220210913/http://www.melbourneheartfc.com.au/default.aspx?s=aleague_newsdisplay&id=35811|archive-date=20 February 2011|publisher=Melbourne Heart}} A significant narrative in derby history is the role of Melbourne Victory as a more successful club both on and off the field, having joined the A-League five years earlier than City. The rivalry is one of the most intense and well respected in the A-League, producing noticeable atmosphere and some of the largest attendances in the league.{{cite web|title=Melbourne Derby: Does Victory v.

"The Original Rivalry" – Adelaide United v Melbourne Victory

The rivalry stems from the traditional cross-border rivalry between sporting teams from South Australia and Victoria but was strengthened by multiple incidents in the 2006–07 season, such as the confrontation between Melbourne Victory captain Kevin Muscat and Adelaide United coach John Kosmina.{{citation needed|date=August 2019}} The two clubs contested the 2007 and 2009 A-League Grand Finals, with Melbourne winning the 2009 Grand Final 1–0 against a 10-man Adelaide United side. The two clubs were also involved in the first and only occasion in the A-League during the 2008–09 A-League season, where they both finished on the top of the ladder equal on both points and goal difference.

"Sydney Derby" – Sydney FC v Western Sydney Wanderers

The derby was contested for the first time in the 2012–13 season with the introduction of the second Sydney-based club, Western Sydney Wanderers, into the league. Sydney FC grabbed bragging rights by winning the first derby 1–0 at Parramatta Stadium,{{cite web|url=http://www.footballaustralia.com.au/aleague/matchcentre/matchreport/Western-Sydney-Wanderers-FC-v-Sydney-FC-Hyundai-A-League/2613|title=Del Piero does it again|date=20 October 2012|publisher=A-League|url-status=dead|archive-url=https://web.archive.org/web/20130403055626/http://www.footballaustralia.com.au/aleague/matchcentre/matchreport/Western-Sydney-Wanderers-FC-v-Sydney-FC-Hyundai-A-League/2613|archive-date=3 April 2013}} however Western Sydney Wanderers won the return match at Allianz Stadium 2–0.

"The Big Blue" – Melbourne Victory v Sydney FC

This match is so named because blue is the main colour of both teams' playing kits, and is also Australian slang for a fight or a contest.{{cite encyclopedia | title=Blue | encyclopedia=The Macquarie Essential Dictionary | publisher=The Macquarie Library Pty Ltd | year=1999 | pages=81}} The rivalry has emerged as a result of a number of spiteful encounters between the teams in recent years, and due to the longstanding rivalry between Sydney and Melbourne, Australia's two largest cities. The teams have competed against each other in three grand finals; in 2010 & 2017, with Sydney winning 4–2 on penalties after a 1–1 draw on both occasions and in 2015, with Victory winning 3–0.{{cite web|url=https://www.a-league.com.au/match/melbourne-victory-v-sydney-fc-a-league-17-05-2015/796853|title=Victory outclass Sydney FC in Grand Final|date=17 May 2015|access-date=23 April 2019|first=John|last=Greco|archive-date=6 January 2016|archive-url=https://web.archive.org/web/20160106070639/http://www.a-league.com.au/matchcentre/Melbourne-Victory-v-Sydney-FC/796853|url-status=live}} In 2010, Sydney FC won the A-League Premiership on the final day of the season by defeating Victory 2–0. A Big Blue match is traditionally played on Australia Day each year.

"The F3 Derby" – Central Coast Mariners v Newcastle Jets

The two teams' stadiums are just one hour apart, and the derby was intensified when they competed against each other for the premiership in the 2007–08 A-League season and eventually met in the Grand Final, which was won 1–0 by the Jets.

In January 2017, Football Federation Australia unveiled their new A-League logo which formed part of a wider rebranding branding of the A-League and its subsidiary competitions, the W-League and Youth League. The logo design was "inspired by soccer's three outstanding features – atmosphere, diversity and unity" and has colour alterations tailored to each of the 12 A-League clubs.

It was the inaugural logo of the league. The two-toned ochre colours represented the sun, earth and desert while the 'glow' emanating from the centre of the logo depicted the playing season's spring and summer time span. The eight 'A' figures that made up the ball shape represented the eight foundation clubs of the league.{{cite web |title=Logo signals refreshing new era |url=http://www.a-league.com.au/default.aspx?s=newsdisplay&id=616 |work=A-League.com.au |publisher=Football Federation Australia |date=1 November 2004 |access-date=19 December 2006 |archive-url=https://web.archive.org/web/20060912080024/http://www.a-league.com.au/default.aspx?s=newsdisplay&id=616 |archive-date=12 September 2006 |url-status=dead }}

In 2005, John O'Neill, FFA CEO commented during the unveiling of the A-League Trophy, "We have a new national league and we feel it is important to re-define the conventional view of a trophy to reflect this". Clive Solari of D3 Design explained the trophy's design, saying "We wanted our trophy concept to embody the historical significance of sport in a contemporary design. So we looked to history to see how great achievements have been rewarded across all types of games for thousands of years. The winners of the world's original sporting competition, the Olympic Games, were presented with a laurel wreath on their heads. We used this model as a basis for a unique, cutting-edge design – our trophy is a modern and versatile translation of the wreath. The winners can hold it above their heads as a symbol of success".{{cite web|title=New A-League trophy revealed|url=http://theworldgame.sbs.com.au/news/647980/new-a-league-trophy-revealed|work=The World Game|publisher=Special Broadcasting Service|access-date=27 February 2014|archive-url=https://web.archive.org/web/20140302222201/http://theworldgame.sbs.com.au/news/647980/new-a-league-trophy-revealed|archive-date=2 March 2014|url-status=dead}}

The A-League match-day squad includes the typical 11 players, and five substitutes of which one must be a goalkeeper. Prior to the 2013–14 season, just four substitutes including one goalkeeper were allowed to be named in the starting line-ups for the teams.{{cite web|title=A-League increases available substitutes to five|url=https://www.sbnation.com/2013/8/15/4624170/a-league-substitutes|author=Orr, Michael|work=SBnation.com|date=15 August 2013|access-date=30 May 2014|archive-date=31 May 2014|archive-url=https://web.archive.org/web/20140531105800/http://www.sbnation.com/2013/8/15/4624170/a-league-substitutes|url-status=live}}

An squad must comprise a minimum of 20 players with a maximum of 26, subject to several limitations. Within the squad, there can be a maximum of five "foreign" or "Visa" players, from outside Australia (and New Zealand, in the case of Wellington Phoenix), that hold a temporary working-visa. Three players in the squad must also be under 20 years of age. In addition to these three under 20 players, clubs are allowed to sign an additional three youth players onto full-time contracts at a lower pay rate than the rest of the squad.{{cite news | url=https://www.smh.com.au/sport/a-league/open-slather-as-clubs-push-for-squad-quotas-to-be-scrapped-20120129-1qo1l.html | title=Open slather as clubs push for squad quotas to be scrapped | work=The Sydney Morning Herald | date=30 January 2012 | access-date=23 August 2013 | archive-date=2 March 2012 | archive-url=https://web.archive.org/web/20120302125751/http://www.smh.com.au/sport/a-league/open-slather-as-clubs-push-for-squad-quotas-to-be-scrapped-20120129-1qo1l.html | url-status=live }}{{cite web|url=http://www.pfa.net.au/index.php?id=81|title=A-League Collective Bargaining Agreement 2008–2013|publisher=Australian PFA|date=2 May 2010|access-date=19 January 2011|archive-date=19 April 2010|archive-url=https://web.archive.org/web/20100419210857/http://www.pfa.net.au/index.php?id=81|url-status=live}}{{cite news | url=http://www.dailytelegraph.com.au/sport/soccer/a-league-salary-cap-to-rise/story-e6frey4r-1111113393772 | title=A-League salary cap to rise | work=The Daily Telegraph | date=23 April 2007 | access-date=11 February 2011}} The A-League had initially proposed that the quota of five visa players per A-League club be reduced to four in the 2015–16 season, with the limit of four possibly become "3+1", which means three imports from anywhere and one from Asia (following regulations in the AFC Champions League).{{cite web | url=http://www.couriermail.com.au/sport/football/reducing-the-aleague-imports-to-four-will-only-help-the-development-of-our-young-australian-players/story-fnk6pqhe-1226855909589 | title=Reducing the A-League imports to four will only help the development of our young Australian players | work=The Courier-Mail | date=15 March 2014 | access-date=15 June 2014 | author=Moore, Craig | author-link=Craig Moore | archive-date=16 March 2014 | archive-url=https://web.archive.org/web/20140316140941/http://www.couriermail.com.au/sport/football/reducing-the-aleague-imports-to-four-will-only-help-the-development-of-our-young-australian-players/story-fnk6pqhe-1226855909589 | url-status=live }} However, after opposition to the proposal by both players and managers, the move was placed on hold.{{cite news | url=http://www.foxsports.com.au/football/a-league/a-league-chiefs-are-set-to-backflip-and-not-reduce-visa-spots-for-next-season/story-e6frf4gl-1227195813689 | title=A-League chiefs are set to backflip and not reduce visa spots for next season | work=Fox Sports | date=24 January 2015 | access-date=16 February 2015 | author=Davutovic, David | archive-date=26 March 2023 | archive-url=https://web.archive.org/web/20230326140240/https://www.foxsports.com.au/football/a-league/a-league-chiefs-are-set-to-backflip-and-not-reduce-visa-spots-for-next-season/story-e6frf4gl-1227195813689?nk=995308bb944d520bc9cc639b95b60832-1679839359 | url-status=live }}

Although A-League clubs have restricted salaries (salary cap), the league since its inception allowed clubs to have two "marquee" players whose salaries are exempt from the cap, plus a number of other 'exemptions' or 'allowances' to incentivise clubs to spend in specific areas. Guest players are also excluded for up to a maximum of 14 league matches.{{cite web|title=Sweeping changes to A-League cap unveiled|website=MSN|url=https://www.msn.com/en-au/sport/football/sweeping-changes-to-a-league-cap-unveiled/ar-BBlD3CO?ocid=mailsignout|access-date=11 August 2015|archive-date=8 December 2015|archive-url=https://web.archive.org/web/20151208040643/http://www.msn.com/en-au/sport/football/sweeping-changes-to-a-league-cap-unveiled/ar-BBlD3CO?ocid=mailsignout|url-status=live}} From the 2008–09 season, A-League clubs have been permitted a junior marquee player; one that is under the age of 23.

Commencing in the 2015–16 season, players who have played at their club for 5–10 years will be covered by a "loyalty player allowance", allowing up to $200,000 of their salary to be exempted from the cap. Additionally, clubs are now permitted a mature-age rookie whose wages are outside the salary cap.

The salary cap for A-League clubs is $2.1 million for the 2020–21 season, in the case for new clubs debuting, they were entitled to a $333,000 allowance thus increasing their salary cap to $2.433 million. Clubs must spend at least the salary floor which is $1.7 million. The salary cap applies to the 18 to 23 players that clubs have registered to their A-League player roster, the top 2 highest-paid players (Designated Players) don't count in the cap.

Players registered at a club for more than 4 consecutive years as a professional are considered as 'Loyalty Players' and have the following amounts exempt from a club's salary cap; Year 4 – 12.5%, Year 5 – 25%, and 5% increments after that up until a max of 50%. Teams can spend an unlimited amount on 4 U-23 Australian players who have come from the youth team, called 'Homegrown Players'. Teams can sign up to 9 U-20 players on minimum wage called 'Scholarship Players' who don't count in the squad unless they are one of the 3 U21's in the squad, any payments above the national minimum wage to these Players are included in the club's Salary Cap.{{cite web|title=Salary Cap System|url=https://www.a-league.com.au/salary-cap-system|access-date=25 December 2020|website=A-League|date=August 2017|archive-date=18 April 2021|archive-url=https://web.archive.org/web/20210418165238/https://www.a-league.com.au/salary-cap-system|url-status=live}}

As of the 2023–24 season, 15 different clubs have competed in the league, with eight having won the trophy, and eight winning at least one premier's plate. 6 clubs have won a Premiership-Championship double, a feat achieved 11 times in total.

The winner of the regular season tournament is dubbed the 'Premier' while the winner of the grand final is the season's 'Champion'. This differs from other football codes in Australia, where 'premier' refers to the winner of the grand final and the winner of the regular season is the 'minor premier'.

It was filmed at Bob Jane Stadium in Melbourne. Other campaigns include the "90 minutes, 90 emotions", which was used for two seasons from 2007 to 2009 and was accompanied by the music track "My People" from Australian act The Presets.{{cite news | url=http://au.fourfourtwo.com/news/58536,aleague-ad-hits-the-screens.aspx | title=New A-League ad hits the screens | work=Australian FourFourTwo | date=9 August 2007 | access-date=6 January 2008 | archive-date=4 March 2012 | archive-url=https://web.archive.org/web/20120304195338/http://au.fourfourtwo.com/news/58536,aleague-ad-hits-the-screens.aspx | url-status=live }}
