The draw for the first round of the Australian Open was originally supposed to take place 3pm local time (04:00 GMT) but was delayed by one hour and 15 minutes.
Prime Minister Scott Morrison held a news conference at 3:45pm, although he declined to comment on when a decision regarding Novak Djokovic would be made.
The nine-time champion has remained the draw - despite uncertainty over whether he will be deported - and is set to face fellow Serb Miomir Kecmanovic.
Elsewhere, Britain’s former world number one Andy Murray has been drawn against Nikoloz Basilashvili - whom he beat in the Sydney Tennis Classic quarter-final this week.
Meanwhile, Spanish sixth seed Rafael Nadal will begin his tournament against unseeded American Marcos Giron.
The rest of the draw
British men’s number one Cameron Norrie will face American Sebastian Korda.
Dan Evans - who is set to face Aslan Karatsev in the Sydney Classic semi-final tomorrow - will take on Belgium’s David Goffin.
Daniil Medvedev, who lost out on last year’s final to Djokovic, will play Swiss Henri Laaksonen.
