People entering Tasmania from Queensland hot spots have been warned they may be refused entry to the state or forced into hotel quarantine.
On Wednesday, Queensland identified three local government areas at risk of coronavirus transmission.
These are the local government areas City of Brisbane, City of Ipswich and Logan City.
Tasmanian director of Public Health Mark Veitch said any person who spent in these areas, or other affected regions, in the 14 days before travelling to Tasmania would need to seek approval to enter the state before travelling.
Those approved would need to spend 14 days in hotel quarantine at their own expense.
In other news:
Dr Veitch said those people who currently have essential traveller status or approval to complete quarantine at a Tasmanian residence, and who may have been in these three areas, will have their G2G application rejected.
Those people will have to re-apply and have their application assessed under new criteria.
Dr Veitch said anyone who has recently arrived in Tasmania from these areas before Wednesday should remain vigilant for respiratory symptoms and seek testing if symptoms arise.
G2G staff are currently working to contact people who may be affected by these changed conditions.
When applying for a G2G PASS to enter Tasmania, people must declare if they have been to one of the locations listed as an affected region or affected premises within the specified period.
For testing information call the Public Health Hotline on 1800 671 738.
