The Check in TAS app will no longer need to be used at a majority of state venues from 6pm, Premier Peter Gutwein has announced.

These venues include cafes, supermarkets, restaurants, retail centres, shops, schools, hospitals and aged care facilities.

Mr Gutwein said check-in requirements would remain in place at bars, pubs, clubs, gaming rooms, casinos, hotels and licenced venues for the time being.

He said the need to check-in to these venues would be reviewed over the next two to four weeks.

"And we'll also be looking at other restrictions, including masks in that period as well," Mr Gutwein said.
