Australia has advised all of its overseas citizens wishing to return home to do so immediately due to coronavirus disorders.
"The more countries close their borders or introduce travel restrictions, the more complex and difficult overseas travel becomes," the Ministry of Foreign Affairs and Trade said in updated guidelines published on its website on Tuesday.
"You may not be able to return to Australia if you planned to."
Australia has already asked citizens not to go abroad.
The updated advice was issued after Prime Minister Scott Morrison met with leaders to discuss tightening restrictions on public meetings.
The government has banned gatherings of more than 500 people, but several heads of state are pressing for the ban to be extended to any event involving more than 100 people.
Morrison representatives did not immediately respond to requests for comments.
As of Monday, Australia has requested that anyone arriving from overseas must isolate themselves for 14 days.
It has stopped taking more stringent measures, such as closing schools or curfewing. The measures are expected to further limit tourism.
The Sydney Opera House, a national symbol, said it would suspend all performances until the end of the month.
The Australian Fashion Week, the Splendor in the Grass music festival, all Cricket Australia games and the World Surf League were canceled because the number of coronavirus cases exceeded 400. Despite Australia, which is lagging behind other countries in terms of coronavirus cases, officials are becoming increasingly concerned about the exponential growth of infections.
New South Wales, the most populous state, saw its highest rate of infection so far in one day on Tuesday. Tourism accounts for 3% of the Australian economy.
Minister of Tourism Simon Birmingham said the government planned "to do everything we can" to help tourism companies and left the possibility of a bailout for Qantas Airways Ltd and rival Virgin Australia Holdings.
Qantas announced on Tuesday that international capacity will be reduced by around 90% by at least the end of May.
Virgin announced profound capacity cuts last week. The Australian financial report said Australia would offer refunds and waive excise duties – measures worth $ 715 million ($ 430 million) to help the industry. "We will recover," said Birmingham.
"We will get out of the corona virus and we need to make sure that our tour operators, tour attractions, all of our critical tourism infrastructures and businesses are able to take part in this recovery as soon as possible. Get people back to work and we get money that flows back through our economy. "
Parliament will meet next week to adopt a proposed $ 17.6 billion stimulus package. However, the number of elected officials returning to Canberra for in-house meetings will be reduced by 40% to reduce the likelihood of the virus spreading.
The central bank, which cut interest rates to a historic low earlier this month, has also pledged additional support.
It was announced on Monday that new measures will be presented on Thursday as more liquidity is pumped into the system.
Speculation is widespread Thursday's announcement would include an RBA rate cut to 0.25% off-cycle and unconventional policy measures.
Treasury Secretary Mathias Cormann said the expected global downturn will be felt the hardest by the poorest Australians. "The Australians, who will lose their jobs in the coming weeks and maybe months, will need adequate support so that we can return stronger and better on the other hand," he told the Australian Broadcasting Corporation on Tuesday.
