Mr Frydenberg defended his decision not to self-isolate after feeling unwell and undergoing testing for coronavirus.

He travelled to Riyadh in Saudi Arabia last month and said he recently came down with a sore throat and runny nose.

He was tested for coronavirus on Thursday and received news on Friday that he did not have COVID-19.

Mr Frydenberg told Sky News he followed the advice of health professionals.

"I had been in Riyadh just over two weeks before and so it was very much a precautionary measure I took," he said.

"The medical advice to me was not to go and self-isolate. I'm pleased the test came out negative."

The news comes after a federal politician tested positive to the coronavirus on Friday night.

Home Affairs Minister Peter Dutton is being treated at Royal Brisbane Hospital after returning a positive test and is preparing to be an inpatient for a fortnight per Queensland Health protocol.

On Saturday, Mr Dutton reported feeling better with a reduced fever.

He is expected to use his secure video-link to dial in to a National Security Committee meeting from hospital today.

Frydenberg test 'nothing to do' with Dutton

A spokesman for Mr Frydenberg said the Treasurer took a COVID-19 test on the day he and Prime Minister Scott Morrison unveiled the coronavirus economic stimulus package last Thursday.

The Treasurer went on a media blitz to sell the $17.6 billion package including an interview on the ABC's 7.30 on Thursday night, commercial television interviews the following morning and a radio interview with the ABC's AM program.

Mr Frydenberg's spokesman said the senior frontbencher received his test results on Friday afternoon.

"The Treasurer was tested for COVID-19 and the results were negative," a short statement read.

But Mr Frydenberg's office said "the testing had nothing to do with Minister Dutton", and the Treasurer was cleared before Mr Dutton revealed his condition.

Mr Dutton had attended a Cabinet meeting with the Prime Minister and his frontbencher colleagues in Sydney on Tuesday.

But the Home Affairs Minister said he only began to experience symptoms on Friday morning.

The country's chief medical officer, Brendan Murphy, said only people who had "close contact" with him in the 24 hours before he began to feel ill needed to get tested.

Plibersek self-isolates during test wait

The Opposition's education spokeswoman, Tanya Plibersek, has confirmed she was given medical advice to get a coronavirus test during the week too.

"I briefly attended a uni conference about a fortnight ago. I was informed on Thursday that a conference delegate may have had COVID-19," she said on Twitter.

"The medical advice was that I should self-isolate and have a test. That's exactly what I did. The test was negative."

Mr Frydenberg was in the ACT in the period after taking the coronavirus test.

According to the capital's COVID-19 advisory, people with symptoms who get tested for coronavirus should "remain in your home and do not attend work, school or any public places" while awaiting the test results.

New measures to come

New measures to try and stop the spread of coronavirus will be considered by senior government figures, as other countries take further steps to protect their citizens.

New Zealand has announced that anyone entering the country from midnight will be required to self-isolate for 14 days, with exceptions only made for small Pacific island nations that have no coronavirus cases.

Prime Minister Scott Morrison is meeting with state and territory leaders today, and will also hold talks with senior federal ministers about Australia's response to the virus.

Mr Frydenberg told Sky News that New Zealand's approach would be discussed.

"No options are off the table," he said.
