Tasmania is on track to open to low-risk coronavirus states and territories in late October, with a call on New South Wales to be made early next week.
The island state already plans to reopen to South Australia, Western Australia, Queensland, the Northern Territory and Australian Capital Territory on the 26th.
Premier Peter Gutwein announced on Tuesday a decision on NSW would likely be made on the 19th.
"We are continuing to monitor the situation in NSW closely," he said after a recent cluster in south west Sydney.
"They are very low numbers in a large population base but we've taken the view... that we should wait another week (before deciding whether to reopen)."
Tasmania will remain closed to Victoria until at least December 1.
All travellers from low-risk states and territories will have to undergo temperature checks when they arrive in Tasmania.
The state was the first jurisdiction to shut its borders and last recorded a COVID-19 case about two months ago.
