A Brisbane man has been cleared of the deadly coronavirus as health professionals prepare to greet passengers arriving into Sydney from the epicentre of the outbreak.
A number of Australians have been tested for the virus which has led to nine deaths from more than 440 cases in China.
Cases have also been confirmed in Japan, Thailand and South Korea.
But Queensland Health on Wednesday confirmed a man who had been isolated after returning from visiting family in the Chinese city of Wuhan does not have the virus.
Australia's Chief Medical Officer Brendan Murphy says it's possible the virus will reach Australia, but insists the nation is equipped.
"It's quite possible we will get a case, but I think we are well prepared to respond," Professor Murphy told Prime Minister Scott Morrison during a briefing at the Department of Health's National Incident Room in Canberra.
Prof Murphy said Australia is ready to respond and isolate any travellers who are suspected of carrying the virus.
Biosecurity measures have been ramped up for flights arriving into Australia from China and Wuhan in particular.
The sprawling capital of central China's Hubei province is the epicentre of the coronavirus which is thought to have started in animals before spreading to humans.
The three flights Sydney receives from Wuhan each week will be closely monitored, starting on Thursday when biosecurity staff at Sydney Airport will assess any arrivals who feel unwell.
The crack team will include four NSW Health doctors and nurses experienced in public health and infection control alongside virology experts from Westmead Hospital and elsewhere.
The team will wear masks and gloves when examining anyone with symptoms, NSW Health protection executive director Jeremy McAnulty told reporters in Sydney.
"If it looks like they may have an infection ... we can arrange for testing and management of that person right away," Dr McAnulty said.
Experts at Westmead Hospital can rapidly diagnose patients although if someone is very unwell they could be taken to a hospital closer to the airport.
Dr McAnulty says identifying potential carriers at the airport is "not foolproof by any means" because people who've been exposed to the virus may not display symptoms for days.
Chinese authorities say they have a deep understanding of the coronavirus and medicines have been distributed across the country.
Australia's foreign affairs department says anyone travelling to Wuhan should "exercise a high degree of caution" while in the city.
Health Minister Greg Hunt said authorities had powers to take those who may be suffering from symptoms directly to hospital.
"They do have the capacity because of the measures taken, to bring people directly to hospital if that were required," Mr Hunt told Sky News on Wednesday.
"But we expect that any passengers that do have issues will self-report because it's in their own interests."
