Victorians will be unable to enter Tasmania without an exemption from midnight tonight.
Premier Peter Gutwein also announced on Wednesday Tasmania would also not be reopening its border to Victoria on July 24, when the state was set to reopen to other jurisdictions.
"Victorians will not be allowed to travel to Tasmania. Anyone who spent time in Victoria in the 14 days prior to travel will not be permitted either," Mr Gutwein said.
"The only exemption will be Tasmanians returning home and they will have quarantine requirements."
Mr Gutwein said Tasmanians returning to the state who had spent time in Victoria in the previous 14 days would have to quarantine in a hotel.
In other news:
Mr Gutwein said Victorians arriving without an exemption letter would be told to go home.
"They will be turned back at their own expense," he said.
Mr Gutwein said exemptions to travel to Victoria and back to Tasmania on compassionate reasons would be unlikely to be granted in the short term.
People transiting through Victoria from other jurisdictions will be able to do so provided they do not leave the airport, Mr Gutwein said.
A further update in terms of travel into and out of Tasmania will be made on Friday.
