The first major sporting event in Australia to be affected was the 2020 Australian Grand Prix, which was cancelled on 13 March 2020 after McLaren withdrew when a team member tested positive for COVID-19. This was also enforced on the support races which included the 2020 Melbourne 400, which was the second round of the 2020 Supercars Championship to be cancelled. The 2021 Australian Grand Prix was postponed from its original March date to November to allow for the easing of travel restrictions. On 6 July 2021, it was cancelled for the second consecutive year due to "restrictions and logistical challenges" related to the pandemic.
