Groups of more than 10 people are no longer allowed to congregate in Tasmania in strict measures to curb the spread of coronavirus.
The order applies to public and private gatherings, Premier Peter Gutwein announced on Friday.
It will be made an offence from 6pm on Friday, with fines of up to $16,800 for those who don't comply.
"What I don't want to see this weekend, is groups of people congregating," Mr Gutwein said.
"We don't want to see backyard parties, we don't want to see parties in the park ... parties at the beach.
"There's no point in the measures we have taken to shut down businesses ... if on the weekend people decide what they'll do on a nice sunny day is take 20 people to the beach and have a few beers."
The ban will end "when the risk has been lowered", Mr Gutwein said.
Parents have been urged to keep their children home from school where possible from Monday.
"There is no increased health risk ... but I understand that parents are concerned and our teachers are anxious," Mr Gutwein said, adding schools will be open until the Easter break.
"Schools will remain open for the children of essential workers, for any parent who doesn't have the ability or support available to them to provide adequate supervision and learning support at home."
The state has already made April 6 to 9 student-free days, effectively cutting term one by four days.
Tasmania has recorded 47 virus cases, the latest five on Thursday night included two children, but none through community transmission.
All five people were passengers on the Ovation of the Seas cruise ship, which docked in Sydney last week, and were all in self-isolation before returning positive tests.
One person is aged in their 70s, with the other two in their 30s.
Mr Gutwein this week ordered all tourists to go home and implored anyone thinking of visiting the island state to stay away.
The Bass Strait ferry service, Spirit of Tasmania, has put on extra trips next week to help people return home.
