Speaking to the Daily Mail, Tiley fears the freedom of travel will be "significantly challenged" at the start of next year but revealed he is coming up with a plan that could keep players in action Down Under through to mid-February.

After the Australian Open, which is due to be held from January 18 to 25 in Melbourne, players are scheduled to ply their trade in different parts of the world.

But should tournaments not go ahead due to the global health crisis, Tiley - who is also the tournament director of the Australian Open - said Tennis Australia could step in to provide more competitions.

"We are talking about the possibility of having a couple of events after the Australian Open," said Tiley.

"It's an open conversation right now with the tours.

"I am of the view that we are still going to be significantly challenged on freedom of travel and by lockdowns in February and March next year.

"It's about how it impacts the rest of the tour and if the tours and the players want it. If they do we would entertain it. It is on the table and they are looking at it.

"They are looking at what happens next season.

"We want to maximise playing opportunities and ideally we want everyone to play at least one event plus the Australian Open, but it could be more."

Players looking to play in Australia from January 1 are due to arrive in the country in mid-December ahead of a two-week quarantine period.

The Association of Tennis Professionals Cup is due take place in Brisbane, Perth and Sydney.

But Tennis Australia is reportedly considering moving all the tournaments to Melbourne which ended its 112-day lockdown on October 28.

There is also doubt over whether the Adelaide International will go ahead after the Adelaide 500 supercar race and the Santos Tour Down Under, part of the International Cycling Union World Tour, were cancelled in recent weeks.

Since the outbreak of coronavirus, Australia has registered 27,668 cases and more than 900 deaths.

But yesterday saw the states of Victoria, Queensland and New South Wales record no new cases.

"Right now the state borders are not open, they've been closed for more than six months," said Tiley.

"We need a guarantee that for instance, if you were playing in Brisbane and all of a sudden 100 new cases cropped up, would you then require a new two-week quarantine coming from there into Melbourne?

"We said from the beginning that if quarantine plans are approved across the states then we can play across the cities, otherwise we have to contract everything to Melbourne, because that's where everyone has to be in late January."

The US Open was staged behind closed doors in September before the rescheduled French Open went ahead in front of a limited number of fans.  

Tiley believes normality will not return at the four Grand Slams for another two years - even if a vaccine for coronavirus is found.

"I'm of the view that these current adjustments will last longer than we think," Tiley told The Daily Mail.

"We are already talking about different (Australian Open) scenarios for 2022.

"That's how we are managing our risks and our cash flow.

"Even if you had a vaccine in March it is still going to be challenging for half of next year."
