During the final, some Sydney United fans sung Za dom spremni (a fascist chant used by the Ustaše in Australia honouring the fascist and genocidal Ustaše movement founded by Ante Pavelić), booed the Welcome to Country, performed salutes commentators characterised as Nazi salutes, and waved flags associated with the extreme far-right Ustaša movement such as the HOS flag and the flag of the WW2 Nazi puppet-state of the Unabhängiger Staat Kroatien.
