The Tasmanian Government is "actively considering" bringing in a vaccine mandate for childcare and early learning workers, and will decide on further mandates for more public sector workers within a week.
The three largest employers in childcare in Tasmania are believed to have already brought in mandates for the staff.
The government has been carrying out a risk assessment on all public sector workforces, while private businesses have also been required to assess the need for mandates for workers, based on Occupational Health and Safety laws.
Premier Peter Gutwein said the public workforce matter would be determined next week.
"We will be finished that process by Wednesday of next week and we'll have more to say whether mandatory vaccination will sit or not across the public sector and government businesses," he said.
TT-Line workers who enter Station Pier in Melbourne are already subject to a vaccine mandate as per Victorian laws. This will be expanded to all TT-Line workers at Devonport to maintain "continuity".
Hydro workers who need to visit the site in Melbourne are required to be fully vaccinated.
More than 94 per cent of Tasmanians aged 16 and above had received the first dose of a vaccine, and 87.5 per cent have had the second dose. The state was set to reach the 90 per cent fully vaccinated mark by December 13 - two days before borders fully reopen to the mainland.
Mr Gutwein said there were concerns that some Tasmanians who had their first dose had not turned up for their second.
He outlined how only fully vaccinated Tasmanians would be able to visit or work at pubs, clubs or festivals where there was stand-up drinking and dancing from December 6.
"The world changes next week," Mr Gutwein said.
No further positive COVID cases have been detected from a Jetstar flight that arrived in Hobart on Monday morning, where a COVID-positive Tasmanian woman in her 40s travelled from Sydney.
She has since been moved from home quarantine to the Fountainside case management facility.
Eleven people were identified as contacts on flight JQ 721 and have been asked to isolate.
Public Health officials have been in regular briefings regarding the Omicron variant, and Tasmania tightened the rules for people who have been overseas since November 14.
Mr Gutwein said there was yet to be any changes to current advice.
Any Tasmanian returning from overseas will need to have a negative COVID test within 72 hours of arrival, be fully vaccinated and undertake quarantine, "regardless of what rules there are in other jurisdictions".
Public Health director Mark Veitch said he expected the global understanding of the Omicron variant - including its transmissibility and health impacts - to be much clearer in the coming fortnight.
