Borders to be shut for at least four more months: chief medical officer
By Dana McCauley
The nation's Chief Medical Officer says Australians should not expect international travel to resume for at least three to four months, saying the risk of importing coronavirus from overseas is too great.
Professor Brendan Murphy told a Senate inquiry into Australia's response to the COVID-19 pandemic that while it was "very hard to put a timeline on anything at the moment", opening borders would be the last stage of any easing of restrictions.

"I wouldn't be envisaging any material changes to border measures in that three to four months," he said.
"The international situation at the moment is such that any relaxation of border measures would be very risky and we just recommended to the national cabinet only a few days ago that we continue the very restrictive bans on people, basically Australians leaving the country, unless there are exceptional circumstances, or anyone except Australian citizens coming back, and then only when they are formally quarantined.
"They are extraordinary measures but the international spread of this virus is huge including to some countries where we know they're not ascertaining cases very well, including in our region."
Professor Murphy said Australia's status as an island nation had allowed it to implement border restrictions "more effectively than other countries" and that "our colleagues in the United States and the United Kingdom regret that they didn't do the same."
"We knew that the greatest risk of uncontrolled transmission was from imported cases," he told a Senate committee hearing into Australia's response to the COVID-19 pandemic.
"We had a huge amount of traffic from China, a very large number of flights."
Professor Murphy also rejected claims that the coronavirus may be spreading in Australia undetected, saying health authorities had expanded testing criteria weeks ago and the results showed it was "very unlikely" widespread community transmission was happening.
"In most jurisdictions, we are testing every single person who has acute respiratory illness," he said. "We would have found evidence of this."
This distinguished Australia from other countries, including in Europe where the coronavirus had spread through "potentially thousands" of people who did not realise they were infected during the winter cold and flu season.
Professor Murphy said he still believed the fatality rate of COVID-19 was about 1 per cent, despite higher figures overseas, saying this was due to low levels of testing meaning "they're not ascertaining cases".
He said Australia was aiming to emulate Taiwan's success in keeping infection numbers low through "aggressive contact tracing and isolation", but warned that there was always a risk of another outbreak.
"We have to be very aware that while we have only had seven cases in the last 24 hours, there is a permanent risk of further cases," Professor Murphy said.
"This is a highly infectious virus and it can take off fairly quickly."
