Australia Cup

The Australia Cup (currently known as the Hahn Australia Cup for sponsorship reasons) is the national soccer knockout cup competition in Australia. This annual competition is organised by Football Australia (known as Football Federation Australia until 2020).

The Australia Cup comprises teams from the top division, A-League Men (known as simply the A-League before the 2021–22 season), as well as those from lower tiers in the Australian soccer league system. Teams enter in progressive stages, with qualifying rounds culminating with the competition proper, starting with the Round of 32. Each of the regional, state or territory-based member federation is granted a team allocation for entry into the main competition, joining clubs from A-League Men.

Initially, all A-League Men's teams entered at the Round of 32. From 2021 to 2025 following further expansion of the league, only the top eight or nine teams entered at the Round of 32, while play-offs were conducted between the four lowest-ranked teams for the final two qualification slots. From 2026, all Australia-based A-League clubs enter at the Round of 32, with New Zealand-based A-League clubs (Wellington Phoenix and Auckland FC) omitted from the competition.

Since 2021, the winner of the competition also qualifies for one of the play-off spots for the following years' AFC club competitions (the AFC Champions League for 2022, the AFC Cup for 2023–24, and the AFC Champions League Two from 2024–25 onwards).

Since the Australian soccer league system provides no promotion and relegation mechanism between the first and lower divisions, part of the competition's appeal stems from the fact that it is the only way that A-League Men and lower-tier clubs can play formal competitive matches.

Adelaide United are the most successful team with three titles. Newcastle Jets are the defending champions after defeating Heidelberg United in the 2025 final for their first Australia Cup title.
