Two Tasmanian women who breached a stay-at-home order after recently returning from Queensland have each been fined $778.50.
Anyone in Tasmania who has been in southeast Queensland since July 17 has been told to isolate amid a COVID-19 outbreak in the mainland state.
About 11,000 people are subject to the direction. They can only leave their home for a handful of essential reasons and must wear a mask when doing so.
A 39-year-old woman from northern Tasmania breached the order by attending a family gathering on Saturday, while a Launceston woman, 52, went to the shops without a mask.
Neither had been in a high-risk premises while in Queensland and the risk to the wider community is considered low.
Tasmania Police will continue to carry out targeted and random checks of those subject to the order.
A group of four Queensland tourists was warned earlier this week for trying to enter a national park when they should have been at home.
"The changing COVID environment with the Delta strain has presented significant challenges in mainland states and we need to ensure the community complies with directions," Inspector John Toohey said.
Tasmania has closed its border with southeast Queensland until at least 4pm on Sunday, with the stay-at-home order in place until that time.
The island state on Wednesday passed the milestone of having 50 per cent of its eligible population receive at least one COVID-19 vaccination.
It puts Tasmania above the national figure of about 41 per cent.
"Tasmania is leading he way, importantly there is still more work to be done," Premier Peter Gutwein told reporters.
More than a quarter of the state's eligible population has received two doses.
The state government will on Monday open up vaccines to people aged 12-15 who have an underlying medical condition or a disability.
