The 2020 edition of the Formula One race was cancelled at the last minute as the pandemic took hold and this year’s Melbourne round was shifted from its traditional season-opening spot to Nov. 21.

Australia’s borders are still effectively closed, however, and the requirement for anybody entering to quarantine for 14 days looks set to remain in place until the end of the year, at the earliest.

“We’re deeply disappointed that for a second consecutive year, both MotoGP and Formula One fans won’t be able to see the world’s best riders and drivers compete at the wonderful Phillip Island and Albert Park circuits,” Australian Grand Prix Corporation Chairman Paul Little said in a statement.

“We appreciate the challenge Australia faces with current international travel restrictions and the importance of vaccinations … We will work tirelessly to deliver these iconic events in 2022.”

Formula One chief executive Stefano Domenicali expressed his disappointment but said he was confident that a 23-race calendar could be maintained for this season.

“We have a number of options to take forward to replace the place left vacant by the Australian Grand Prix,” he said.

“We will be working through the details of those options in the coming weeks.”

MotoGP organisers have moved the Malaysia Grand Prix forward by a week to fill the gap left by the Australian race on Oct. 24 as well as adding a second Portuguese round, the Algarve Grand Prix, to the calendar on Nov. 7.

Race organisers had been in negotiations with Australian authorities for an adjustment to the quarantine policy, which made the races logistically impossible given the Formula One and MotoGP teams were competing in other countries on Nov. 7.

Victoria’s Sports Minister Martin Pakula said it was possible that situation might have improved by October but the government was not able to make a commitment on that now.

Pakula was confident that the country’s vaccine roll-out, which has been one of the slowest in the developed world, would be accelerated to the extent that restrictions would not impact the Australian Open tennis tournament in January.

The Grand Slam was held earlier this year after the players agreed to quarantine for two weeks in hotels but indications are that they would not be prepared to do so again.

“I’m very confident that the Australian Open will proceed,” Pakula told reporters.

“It may not sound like a lot, but we would expect the difference between November and January to be quite profound.” (Reporting by Nick Mulvenney in Sydney, editing by Peter Rutherford)
