Chief Nursing and Midwifery Officer Alison McMillan said while an outbreak in Queensland is being monitored "very closely", she didn't think there was a need to change the requirements of politicians travelling from the state.

Queensland recorded two new cases on Sunday that were linked to the Brisbane Youth Detention Centre, with a total of nine cases now associated with that cluster since a worker was diagnosed with the virus on Wednesday.

"I don't believe there is any need at this point in time to do anything further for the politicians returning from Queensland," Ms McMillian told reporters in Canberra.

"I would suggest they are already here."

Many Victorian MPs including Treasurer Josh Frydenberg were forced into 14 days of quarantine so they could attend parliament this week.

Meanwhile, Labor is expected to focus on the aged care crisis that has stemmed from the pandemic in parliament this week.

The national COVID-19 death toll has topped 500, with many new fatalities again coming from the aged care sector in virus-hit Victoria.

A further 11 deaths in Victorian aged care facilities were reported on Sunday out of a total of 17.

It takes the state's toll to 415 and the national total to 502.

Victoria also reported 208 new infections on Sunday, the first time above the 200 mark in three days.

Victorian chief health officer Brett Sutton said although the daily case numbers were "jumping around", he expected they were on a downward trajectory.

"We're not going to see 300 and 400 again (cases) in Victoria under my watch at least," he told reporters.

NSW recorded four new cases, including a hotel security guard who worked at Sydney's Marriott Hotel.

Western Australia recorded one new case, an interstate traveller who had returned from overseas and tested positive while in hotel quarantine.
