MotoGP's Grand Prix of Australia, which was set for October 24 at Phillip Island in Melbourne, has also been cancelled.

It marks the second year in a row that the F1 race has been cancelled due to COVID-19 after the 2020 event was called off on the race weekend after staff members from McLaren Racing tested positive for the virus.

The Australian Grand Prix was set to take place from November 19 to 21.

Australian Grand Prix Corporation chairman Paul Little said he was "deeply disappointed" in a statement.

"We appreciate the challenge Australia faces with current international travel restrictions and the importance of vaccinations," said Little.

The 2021 race was set to open the season on March 14, but it was postponed due to travel restrictions at the time.

Before its cancellation, it was set to be one of the last races of the season, and was set to be followed by the new Saudi Arabian Grand Prix and the Abu Dhabi Grand Prix.

Australia requires visitors to quarantine for 14 days.

F1 chief executive Stefano Domenicali said a 23-race season would still be possible despite the cancellation.

"While it is disappointing we won't be racing in Australia this season, we are confident we can deliver a 23-race season in 2021 and we have a number of options to take forward," said Domenicali.

The 2019 Australian Grand Prix was won by Finland's Valtteri Bottas of Mercedes.

Dutch driver Max Verstappen of Red Bull Racing is the leader of the World Drivers Championship by 32 points after nine races.

Australia is the fourth nation to have a race cancelled following the Chinese, Canadian and Singapore Grands Prix.
