The Australian Medical Association (AMA) has backed South Australia’s call to keep its borders closed throughout the worst of the COVID-19 pandemic as a second wave of cases grips Victoria.

The Victorian Government has extended its state of emergency and reinstated some restrictions as it grapples with its fifth consecutive day recording a double-digit increase in cases.

The AMA’s SA president Chris Moy threw his support behind SA’s approach to its borders, telling the ABC that Victoria has been a failed test case.

“They were complacent before the time they actually snuffed it out,” Dr Moy told the ABC.

The news from over the border has led to the SA government confirming that it will rethink its planned removal of Victorian travel restrictions, which are currently scheduled for July 20.

Meanwhile, increased security has been introduced at the Victoria-South Australia border as SA seeks to stave off a second wave of the virus here.

Dr Moy said that doctors in SA were worried by the idea of reopening the state’s borders when other states are seeing a surge in the virus’s spread.
