Mr Andrews said if community transmission rates continued to remain low and testing rates continued to remain high, the government would look to further relax restrictions from June 22.

He said from that date, indoor fitness and recreation facilities would open with up to 20 people in a space and up to 10 people in a group or activity at any one time.

Up to 50 people would be permitted in restaurants, cafes, galleries and museums, plus cinemas and theatres.

Mr Andrews urged people to be cautious and use common sense.

"By making these small sacrifices, we're each contributing to something much greater than ourselves," he said.

"Working from home means we can go away for the weekend. Staggering start times means our kids can start learning face-to-face. Keeping our distance means we can open cafes and restaurants. And by only seeing those you need to, if you need to, we can help keep our friends and families safe.

"Because we all have a part to play. And it's up to all of us to make this work."
