The number of active cases dropped from seven on Friday morning, the Department of Health confirmed in a tweet.

Nearly 20,000 people sought tests for the virus on Thursday.

State and federal leaders plan to meet on Friday at the National Cabinet to plan the next stage of the pandemic response.

They will receive a report from Department of Prime Minister and Cabinet secretary Phil Gaetjens looking at how Australia will live with coronavirus after the vaccine has been made available to all Australians this year.

When the national cabinet last met in February, the leaders agreed to create a new taskforce, led by Mr Gaetjens and his state and territory counterparts to advise leaders "about consistent and coordinated COVID-19 responses across jurisdictions in the new risk environment".

"The new taskforce will consider the changed risk indicators associated with new strains of the COVID-19, alongside the strength of risk responses to date and in the future, including most significantly the impact of the vaccine rollout commencing in late February," Scott Morrison said in a statement following the last meeting.

NSW Premier Gladys Berejiklian has already signalled she wants the measurement of success against the virus to change from a goal of zero cases, to a goal of keeping people out of hospital.

It's a change of mindset that may be hard for some states, who have favoured quick lockdowns and closed borders after less than a handful of cases.
