The Australian Open is known as the “Happy Slam” for its convivial atmosphere but the coronavirus has cast dark clouds over this year's build-up and could cause more chaos during the next fortnight, AFP reports.

It will be an Australian Open like no other, with attendances reduced by half and social distancing, mandatory mask-wearing and sanitising stations around Melbourne Park. Officials will be wary of further problems from Covid-19, which ruined the tournament's run-up and caused grumbling from players and Melbourne residents alike.

Tournament director Craig Tiley, who has faced complaints from players over quarantine, and public anger over the Covid risk of flying in competitors and officials from abroad, said he was prepared to order a further halt if necessary. “If we have to go through this again, we'll go through this again.”
