Origins and early success (2018–2024) In August 2018, the Western Melbourne Group was one of the eight teams that the
FFA had accepted in the official bidding phase, as part of the new expansion process. Four months later, the bid's success was announced, along with the bid from
Macarthur FC. Western Melbourne played home games at
Kardinia Park in
Geelong for its first two seasons, while building its stadium and training centre in
Tarneit, with completion expected in 2021. On 11 January 2019, Western Melbourne Group announced
John Anastasiadis as senior assistant coach for the club's debut season. On 24 January 2019, the consortium announced that
John Hutchinson would also join the club as an assistant coach. On 31 January 2019, Western Melbourne made its first player and marquee signing
Panagiotis Kone ahead of its inaugural season. On 12 February 2019,
Socceroos defender
Josh Risdon became Western Melbourne's first Australian signing. On 13 February 2019, it was announced that the club would be called
Western United Football Club after a public vote was held through the
Herald Sun newspaper. The club's colours of green and black were also chosen via the same public vote. In May 2019, Western United announced partnership with sports brand
Kappa. Two months later, the club unveiled their inaugural jerseys for their first season in the
A-League, featuring green and black stripes. On 2 June 2019 the Director of Football for Western United, Steve Horvat presented Geelong representative players with their kits for the 2019 Country Championships. Horvat additionally announced the club would set up a Geelong-based academy by 2021. On 28 May 2022 they became A-League champions, defeating defending champions Melbourne City in the
2022 A-League Men Grand Final. Their Grand Final win saw Western United became just the second expansion side ever to win the A-League Championship, the quickest expansion side to win the championship, the first team since to triumph in their first grand final appearance since Brisbane Roar in 2011, and one of just two teams to have won the championship after finishing outside the top two, with Melbourne Victory first achieving this feat in 2018. The 2022–23 A-League season saw Western United become the first A-League champion in 6 years to fail to qualify for the A-League finals, with the club finishing the season in 7th place on 32 points, with a final tally of 9 wins,5 draws and 12 losses. In October 2023, it was announced that Western United had been given approval from the Wyndham City Council to play home A-Leagues matches at their training ground, the Wyndham Regional Football Facility, in the 2023–24 A-League season, with the venue to serve as Western United's temporary home stadium until the
Wyndham City Stadium is completed. The 2023–24 A-League season started promisingly for Western United, with the club recording a 2–1 win over Melbourne City at AAMI Park. However, this was followed by a run of 6 consecutive losses, with this losing run halted with a 2–1 win over Brisbane Roar. Western United eventually finished the season in 11th place, their worst league finish to date, ensuring that the club missed finals for the second straight season.
Ownership challenges and financial uncertainty; hiatus (2025–26) Debts and wind-up On 1 May 2025, it was reported that the club was subject to a player registration ban by
FIFA, effective until the January 2027
transfer window. Media reports indicated that this was due to a dispute with former player
Aleksandar Prijovic. On 2 May, the club's owners announced that KAM Melbourne would acquire a majority stake in the club, subject to the approval of
Australian Professional Leagues and
Football Australia. Later that month the club was served with breach notices by both their men's and women's teams over unpaid wages. with liabilities exceeding assets by more than $55 million, and a deficit of more than $12m for the preceding period. By this point the proposed KAM Melbourne takeover had not eventuated and then they formally pulled out on 27 August. On 29 August, the club's
parent company WMG Football Club Limited was
placed in liquidation, after a
Federal Court order.
Suspension of license On 8 August, the First Instance Board of Football Australia determined that Western United had failed to meet the criteria to hold an A-Leagues license. The renewal of the club's license was rescinded, with the club subsequently ejected from both Australian Professional Leagues (APL) competitions – the A-League Men and the A-League Women. Appeal by the club followed, with the Football Australia appeals body set to rule on it on 25 August 2025. On 2 September, Football Australia's Appeals and Entry Control Body (A&ECB) adjourned its decision on the matter of Western United's licence until 9 September. The decision received harsh criticism from the PFA president
Beau Busch, who described it as a "let down [of players] by governance failures and false promises". On 10 September, the A&ECB determined that the club's appeal had to go to a new hearing, and in the interim the previous licence withdrawal has been set aside. == A-League Women ==
