Supercars officials will scramble to re-schedule the cancelled Melbourne round, but more events could be in jeopardy as the coronavirus spreads.
Teams at Albert Park are packing up after the Australian Formula 1 Grand Prix was called off because of the global health pandemic.

It left Supercars officials with no other option but to follow suit following a member of McLaren's F1 team testing positive for coronavirus.

"Supercars will continue to adhere to government health advice and act to ensure the health and safety of our fans and our people remains our primary focus."
With the next round at Symmons Plains in Tasmania three weeks away, those races could be held without fans or not at all.
On Friday, Australia's chief medical officer told state and federal leaders that gatherings of more than 500 people should be cancelled.
