The 2023 Australia Cup was the tenth season of the Australia Cup, the main national soccerknockout cup competition in Australia. Thirty-two teams contested the competition proper, with the winner qualifying for the 2024–25 AFC Champions League Two.
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 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 2022–23 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.
