There have been 13 upsets known as 'Cupsets' since the 2014 edition of the Australia Cup where a local Member Federation team has defeated an Isuzu UTE A-League outfit.
Adelaide City recorded the first Cupset after a 1-0 win over Western Sydney Wanderers at Marden Sports Complex, while the most recent was also achieved by a South Australian side when Campbelltown City overcame Macarthur FC 2-1 in the 2023 Round of 32.
A remarkable three cupsets occurred in 2022 - the most in any campaign - with Sydney United 58 FC responsible for two of them on its way to reaching the Cup Final.
