Meanwhile, a 20-year-old man from China has become a 10th Queensland coronavirus case. The man, who had travelled to Dubai for at least two weeks before entering Australia, is in a stable condition in isolation in the Royal Brisbane and Women's Hospital.
He was living in the Brisbane suburb of Toowong with a male housemate, who is now being assessed for the disease.
The new case brings the number of cases in Australia to 34. Fifteen were the early cases among a Wuhan tour group. Ten cases are from the Diamond Princess cruise ship.
The other nine are made up of six in arrivals from Iran in recent days, two transmitted locally including a Sydney medic and the sister of an Iranian returnee, and the latest case from China via Dubai.
This week, Attorney-General Christian Porter spelled out his powers to force people into treatment and isolation and to ban events.
The Biosecurity Act allows authorities to declare a "human biosecurity control" over someone who has been exposed, Mr Porter said. They could then be forced to disclose information about contacts and be forced to stay at a specified place, including detention.
Mr Porter said people were familiar with that power at airports but should now prepare for it to be used at hospitals and medical centres, where people could be forced to undergo decontamination.
For a fever clinic were people recover after the acute phase, relatives might be prevented from entering or leaving, and relatives or medical staff might be required to do through contamination, he said.
"What is likely to happen is that people will find that there will be more refinements on them coming and going into places particularly medical facilities.
"People are used to walking into hospitals in Australia and emergency department rooms, without necessarily having to go through a decontamination or being questioned.
"It may be that, as this disease does roll through the Australian community that those type of circumstances will change, and there'll be greater controls on people's coming and going to certain places where the disease is prevalent."
He also foreshadowed "particular requirements and things that we would be very wise to do before we come and go from childcare or schools".
A "human health response zone" can also be declared to stop people going to schools, shopping centres, work or other places.
But he stopped shot of telling people not to shake hands.
On Monday, NSW Health Minister Brad Hazzard said Australians should cease shaking hands to avoid the virus spread.
Mr Porter said he had a team going through all the laws that would need to be activated for the first time at scale in Australia to ensure the necessary powers were in order.

The government used its Biosecurity Act powers to restrict the movement of Australians on board the Diamond Princess cruise ship. The ship was declared a human health zone, giving Australian authorities the power to handle the return and quarantine of passengers.
"It's very important for all Australians to understand that there are powers ... that they may never have experienced before at all or on any scale and which may become necessary to use in the months ahead," he told parliament on Monday.
There were just over 90,300 confirmed cases globally on Tuesday morning, according to the Johns Hopkins University real-time monitor. The biggest outbreaks have occurred in China (80,026), South Korea (4335), Italy (2036) and Iran (1501).
There have been 3085 deaths: China (2912), Iran (66), Italy (52) and South Korea (28).
By Tuesday morning, 135 people had been tested in Canberra, all negative.
Mr Hunt said more than 10,000 coronavirus tests have been carried out in Australia so far, with 33 people returning positive results.
They include 15 linked to China, who have all cleared the virus, and 10 people who became infected after travelling on the Diamond Princess cruise ship in Japan, before being evacuated to Australia.
Of the 10 aboard the ship, six have now cleared the virus and have been allowed to go home. One of the 10 was James Kwan, 78, the first Australian to die from the virus. His wife is also infected and she remains in hospital.
Chief health officers from all states and territories will meet on Tuesday to discuss ongoing containment and response strategies, as Australians were urged to limit physical contact.
