Tasmania has downgraded Greater Brisbane to low risk but has kept 10 Sydney local government areas at medium risk.
Those in the Greater Brisbane area can freely enter Tasmania without quarantining for 14 days.
Premier Peter Gutwein also announced some changes to allow parts of Greater Sydney to enter the state.
Residents in the 10 Greater Sydney areas will be required to quarantine for 14 days upon arrival in Tasmania.
The 10 areas of Greater Sydney are: Blacktown, Burwood, Canada Bay, Canterbury-Bankstown, Cumberland, Fairfield, Inner West, Liverpool, Parramatta and Strathfield.
Both changes come into effect from 12:01 on Friday morning.
