It comes after the Department of Education's recent audit on every DoE owned building, to collect data on heating, cooling and ventilation.

However, Mr Willie called for "greater transparency" and wanted to the data to be publicly released.

"I think the government should be transparent with all Tasmanians on how they're going to keep students and staff safe in our schools," he said.

"Nobody will be surprised that many of our school buildings are older and may not be designed for adequate airflow or to be COVID safe.

""Delta doesn't discriminate based on age and it's vital our state is prepared if or when the virus enters our borders."

Minister for Education Sarah Courtney said improving ventilation was just one measure the state government was looking at to minimise the risk of COVID-19 in educational settings, in addition she cited extra site cleaning and identifying opportunities for outdoor learning.

Tasmania's border will reopen to fully vaccinated and COVID-negative people from all states and territories on December 15 provided 90 per cent of eligible Tasmanians are vaccinated.

The latest modelling for Tasmania estimates there could be more than 51,000 positive cases of COVID-19 and 87 deaths within six months of the borders reopening.

"With the Premier saying that delta will come to Tasmania, safety and preparedness in our state schools will be critical," Mr Willie said.

"Ventilation and air purifiers are one fundamental way the government can help reduce the risk of COVID spreading in schools.

"Other states have been quick to install purifiers and fix other ventilation issues but aside from a Department of Education audit, we still don't know what necessary upgrades have been undertaken in Tasmanian schools."

Ms Courtney said the data from the recent audit was in the process of being analysed and each room would be examined on an individual basis to asses extent of heating, cooling, and ventilation in place.

"We will continue to work closely with Public Health and schools on this matter, and will take all action necessary to ensure the safety of our children," she said.
