The number of confirmed cases of COVID-19 in Australia has soared over the past day, increasing from 1,098 Sunday morning to 1,479 Monday morning and then to 1,709 Monday afternoon.
In a rare practice, the Australian Health Department updated the number twice Monday.
Speaking at a press conference on Monday afternoon, Chief Medical Officer Brendan Murphy stressed the importance of social distancing to slow the spread of the virus, calling on Australians to "come down hard" on colleagues and friends who ignore self-isolation measures.
"This is the world of social distancing. This is a new way of us interacting with each other all of the time," Murphy told reporters in Canberra.
"Every single Australian who lands on our shore, whether it's from a cruise ship or a plane, or any other means of transportation needs to rigorously quarantine for 14 days now."
As of Monday morning there had been 135,000 tests for COVID-19 undertaken in Australia.
In a post on social media on Monday, Nick Talley, the editor-in-chief of the Medical Journal of Australia, announced that a further 500,000 testing kits that deliver results within fifteen minutes would arrive in Australia within a week.
According to an analysis of Department of Health data conducted by News Corp Australia on Monday, almost half of confirmed cases in Australia are people under the age of 49.
The two groups with the most number of confirmed infections were 25 to 29 and 30 to 34.
