Victoria on high alert as NSW covid outbreak breaches border.
Two new positive cases detected in a Melbourne family returning home from NSW with red zone permits and two members from a NSW removalist crew traveling through Victoria and SA also testing positive.
The cases come after Victoria recorded its 12th day of no locally acquired cases.
Victoria Police Acting Deputy Commissioner Michael Grainger says an extra 90 officers have been sent to the border on top of the 260 operating there since last week.
