Tasmanians have used the Check In TAS app upwards of 11 million times ahead of a deadline for businesses and venues to implement the service which is set to see infringements issued.
To date 28,000 business in Tasmania have registered for the app while the state government continues its push to get the remaining about 12,000 venues to join the plight.
Applications for businesses to register for the app first opened on November 26 last year with the app available for public download from December 1.
"28,000 businesses and venues across Tasmania have adopted [the app] now, have it in practice and are encouraging and assisting their customers and patrons to check in whenever they come to those businesses," cabinet minister Roger Jaensch said.
"There is a requirement now for a wider range [of businesses to use the app] ... we're encouraging them, providing information and support and making it as easy as possible for businesses to take it up."
Mr Jaensch said while a leeway period existed ahead of the end of July deadline for the expanded range of businesses to implement using the app, penalty notices would be issued to non-compliant venues or customers who did not follow the new directions.
He said the overarching necessity for the app was to keep Tasmania on top of COVID-19 as interstate areas battled with outbreaks where daily recorded cases remained out of control.
NSW recorded 105 locally acquired cases on Sunday while Victorian cases jumped into double figures over the weekend.
Three deaths related to the virus were recorded in NSW through the week.
"[The Check in TAS app] is one of the tools we have ... as we watch the coronavirus develop and evolve in Victoria and New South Wales and elsewhere," Mr Jaensch said.
"It's a great reminder to us probably of when, not if, coronavirus will turn up in Tasmania again and how we need to be prepared to be able to limit the risk of wider scale lockdowns and disruptions to our lifestyles and our businesses."
It has been 341 days since Tasmania recorded a case of COVID-19. In the meantime snap border closures have been enforced based on state Public Health advice, and information from national cabinet gatherings acted on.
Mr Jaensch said the government was ensuring any Victorian travellers in Tasmania were abiding by the rules by "putting up lots of information", advertising and doing media.
"People who have entered the state from other places will have made some declarations about their travel arrangements to there is the capacity to do some follow up," he said.
"But over and above anything else we're relying on the good faith and the good will of Tasmanians to follow the instructions in the interest of keeping themselves and their fellow Tasmanians safe."
Stopping short of endorsing members of the public to dob in COVID rule breakers, Mr Jaensch said if anyone observed someone doing the wrong thing they should help to ensure they knew the most up to date public health advice.
