Chief Medical Officer Brendan Murphy says not enough is known about COVID-19 to provide a 12-month strategy on relaxing restrictions and that Australia would continue testing for the “foreseeable future”. Follow live.

How did it start?
The facility’s operator, Anglicare, learnt one of its employees tested positive for COVID-19 on April 11.
The female staffer worked six shifts despite displaying mild coronavirus symptoms.
It was not the first aged care home in NSW to have a confirmed coronavirus case, and Health Minister Brad Hazzard pleaded with workers in the sector to stay home if they were feeling sick.
On April 18, a 93-year-old man became the first COVID-19 death at the facility and there have been regular fatalities since.
What has happened since?
Mr Millard says the nursing home has become a “pseudo-hospital” since it began quarantining its residents, but for a time its resources were stretched.
At one point, more than 55 of its staff were on paid leave either because they contracted the virus or had been ordered to self-isolate at home.
The the state’s chief health officer Kerry Chant reported the carer who introduced the bug to the facility was “absolutely mortified” about the situation.
Mr Millard made desperate pleas to the Federal Government to help with staff shortages, and it has since been offered “unlimited workforce support” by the Commonwealth.
Mr Millard said the workforce was operating at an “extremely high level for a residential aged care facility” with almost two dozen registered nurses, 25 carers, 11 cleaners and other visiting medical specialists.
