A raft of restrictions are expected to be eased this weekend in Victoria, with one major change to test the state's COVID-19 response.

“Sunday is going to be an important day, we’re on track to make some significant announcements,” Premier Daniel Andrews said earlier in the week.

The government has already outlined a number of restrictions set to ease on Sunday, with a huge change seeing Melbourne residents allowed to travel to regional Victoria again.

Multiple health experts have said this will be the true test to see if Victoria can keep virus cases under control with more movement across the state.

Australia recorded another “doughnut day” on Thursday, with no new locally transmitted coronavirus cases across the nation in the previous 24 hours.

Federal Health Minister Greg Hunt confirmed the happy news on Thursday afternoon.

“The latest advice from the National Incident Centre is that Australia has once again recorded a zero community transmission day – this occurs at a time when the world has recorded its second highest daily global case numbers and sadly its highest daily loss of life,” Mr Hunt wrote on Twitter.

However, residents in western Sydney are being urged to get tested for coronavirus after traces of the virus were detected at a sewage pumping station in the area.

NSW Health confirmed fragments of COVID-19 were identified in samples taken on Wednesday from the sewerage system that drains parts of Leppington, Catherine Field, Gledswood Hills, Varroville and Denham Court.

“Symptoms like a runny nose or scratchy throat, cough, tiredness, fever or loss of taste or smell can all signal COVID-19,” a statement read.

“After testing, you must remain isolated until a negative result is received.”
