The 2023 Australia Cup was the tenth season of the Australia Cup, the main national soccer knockout cup competition in Australia. Thirty-two teams contested the competition proper, with the winner qualifying for the 2024âÂÂ25 AFC Champions League Two.
Macarthur FC were the defending champions, but were eliminated by Campbelltown City in the Round of 32.
Sydney FC won its second Australia Cup after defeating Brisbane Roar in the final. This also resulted in qualification to the group stage of the AFC's 2024âÂÂ25 AFC Champions League Two competition.
A total of 32 teams participated in the 2023 Australia Cup competition proper.
A-League Men clubs represent the highest level in the Australian league system, whereas Member Federation clubs come from level 2 and below.
Member federation teams competed in various state-based preliminary rounds to win one of 22 places in the competition proper (at the Round of 32). All Australian clubs (other than youth teams associated with A-League franchises) were eligible to enter the qualifying process through their respective member federation; however, only one team per club was permitted entry into the competition. The preliminary rounds operate within a consistent national structure whereby club entry into the competition is staggered in each state/territory, determined by what level the club sits at in the Australian soccer league system. This ultimately leads to round 7 with the winning clubs from that round entering directly into the round of 32. Slot allocations were the same as the previous year.
The top eight placed A-League Men clubs from the 2022âÂÂ23 A-League Men season gained automatic qualification to the Round of 32. The remaining four teams entered a play-off series to determine the remaining two positions.
