Check In TAS app changes come into effect July 7 to improve COVID-19 contact-tracing

As of July 7, people will need to check in using the Check In TAS app as soon as they enter a business or location where mandatory check in is required.

Previously, check in was only required after a person had been at a business or location for a minimum of 15 minutes. But now, no matter how long a person stays, they must register their visit for potential contact tracing.

More changes would come into effect later this month, when the list of locations where check in was mandatory expands to include accommodation.

Hotels, motels, serviced apartments, hostels, boarding houses, caravan parks, campsites and camping areas, bed and breakfasts and short stay accommodation, except where the premises is the persons' residential premises, will be added to the list of locations from July 31.

Tourism Industry Council Tasmania chief executive Luke Martin said the tourism industry was receptive to the changes.

"I think the industry is trying to be very responsible in doing the right thing," he said. "I've had no operators, certainly in the tourism space, give me any push back in using the Check In app."

Mr Martin said it was in the industry's interest to lead by example.

The new rules would also apply to workers, but they would only need to check in once a day.

It comes a week after Premier Peter Gutwein announced checking in would be mandatory at supermarkets, shopping centres and big box retailers such as Bunnings.

Other premises included in the new mandatory check in rules were libraries, child care centres, schools, residential aged care facilities, hairdressers, vets, mobile food vans and stalls, and markets and fairs.

Minister for Small Business Jane Howlett said Tasmanian businesses had so far embraced the process.

"It's important that we do everything we can to keep Tasmanians safe and this includes strengthening our ability to track and trace should a COVID-19 case be detected in Tasmania," she said.

Mr Martin said he did not think the changes would cause any more of a burden on businesses.

More than 21,000 venues and events had registered for the app as of last week, and it had been downloaded more than 570,000 times.
