Australia reaches 100 casespublished at 05:00 Greenwich Mean Time 10 March 2020
However almost all of them - excluding three deaths - are pretty mild cases, says the nation's chief medical officer Dr Brendan Murphy.
He said over half of Australia's infected patients so far have recovered.
Australia has still only recorded one case of "community transmission", which happened in an outbreak in northern Sydney. That shut downs schools, an aged care home and is affecting a hospital.
"New South Wales and Sydney is still the significantly biggest part of our outbreak in Australia," Mr Murphy said.
Authorities say they're at the point where they're still fighting to contain the disease - so their focus is on returned travellers and people who have been in touch with confirmed cases.
