The Australian Open could be held as late as April as reports surface event planning has been thrown into chaos.
The Victorian Government's position is set to be that players arriving from overseas would not be allowed into the country until January 1 giving players a handful of days after quarantine to prepare for the event.
Premier Daniel Andrews could not be certain when the tournament would be held.
"This is not a simple thing, to have many hundreds or indeed potentially well more than 1000 athletes and others who support them, media, being here for a very important event," Andrews told reporters on Saturday.
"It has to be done safely, it has to be done right. I am very confident we will have an Australian Open in the early part of next year.
"The exact timing of it, the exact arrangements we put in place, they are not settled yet and as soon as they are I will be more than happy to share it with you."
