On Tuesday, Victorian premier Daniel Andrews announced that 10 Melbourne postcodes will go back into lockdown after a recent spike in coronavirus cases.

Now, the NSW government has revealed Victorians from affected hotspot suburbs will face fines of up to $11,000 – and up to six months’ jail time – if they enter the state.

The penalties were shared by NSW health minister Brad Hazzard on Wednesday.

“Victorians ... from those hotspots are not welcome in NSW. We’re sorry. It’s not something we want to do, but it’s something we must do for our safety,” Hazzard said

The same penalties will apply to NSW locals entering Victoria’s hotspots.

“The message to NSW residents is: don’t go to Victorian hotspots,” Hazzard said. “Just don’t go.”

Stage-three restrictions will be reimposed on affected Melbourne suburbs from 11.59pm on Wednesday evening, and will remain in place until at least July 29.

Residents will only be permitted to leave their homes to shop for food and other supplies, to exercise, to study or work (for those who cannot do so from home), and for compassionate reasons.

“Regular police patrols, both in these zones and outside them, will make sure people are abiding by the restrictions,” Andrews said.

The postcodes affected by the new restrictions are:
