Tasmania will downgrade all of Queensland to "low" COVID-19 risk from Wednesday, allowing travel without quarantine between the two states.
Only Queensland travellers who have been in a listed "high-risk" premises will still face restrictions.
The COVID outbreaks on the mainland have led Tasmanian health authorities to ban travellers from Victoria, New South Wales, the ACT and anyone from the Northern Territory who has been in Greater Darwin and Katherine.
Only returning Tasmanian residents and anyone deemed an essential traveller can receive a G2G pass to enter the state from those jurisdictions.
Premier Peter Gutwein said Tasmania remained "under constant threat" from the Delta strain of coronavirus.
He said the ban in place for those coming from NSW would "remain in place for the foreseeable future".
Travellers cannot drive through NSW at all
Mark Veitch, the director of Public Health, said even people who "drive their car through New South Wales" would be deemed to have been in a high-risk area by Tasmanian authorities.
That means Queensland travellers hoping to avoid quarantining will not be able to drive through NSW, even just with stops for fuel, in order to reach Tasmania on the Spirit of Tasmania ferry.
Those who attempted it would be "required to go into hotel quarantine, if indeed you are allowed into Tasmania at all", Dr Veitch said.
Dr Veitch said the "worst-affected" area of Dubbo was of concern due to the region "very quickly reaching well over 100 cases", pointing to the "very mobile population".
Mr Gutwein also said attendees at Sunday's AFL fixture between St Kilda and Fremantle at Blundstone Arena would be required to wear masks.
He said teams and staff would be regularly tested and leave after the match is completed.
