In 2021 most of the usual tournaments were either relocated to Melbourne Park or not held at all, as a result of international and domestic travel restrictions imposed by the COVID-19 pandemic. The 2021 ATP Cup was moved to Melbourne Park but cut to 12 teams, whilst two WTA tournaments (the Gippsland Trophy and Yarra Valley Classic) and two ATP tournaments (the Great Ocean Road Open and Murray River Open) were held at the park in the lead-up to the 2021 Australian Open. An additional WTA tournament, the Grampians Trophy was later added for players who had to undergo strict quarantine measures upon arrival in Australia, serving as preparation for the Australian Open. Two other WTA tournaments, the Phillip Island Trophy and Adelaide International, were staged in the last week and week after the Open. All of the new alternative tournaments except one (sans Adelaide) take place in Melbourne Park but are named after various places in the state of Victoria.
