Premier Peter Gutwein has declared parts of Queensland as high risk due to that state's snap lockdown.
Mr Gutwein said he had been briefed on the developing situation in Queensland and the Tasmanian Government was reacting accordingly.
"Up until this point we have been managing Queensland on a hotspot basis, where we had 27 hotspots declared high risk, and if people had travelled there at a certain time they were not allowed entry, and anyone from Tasmania who had visited those locations was placed into quarantine," Mr Gutwein said.
He said two Queenslanders were in hotel quarantine and two people who had visited hotspots were in hotel quarantine.
"In line with Queensland's announcement that as of 5pm today they will be having a three day lockdown, Tasmania will, effective immediately, be putting in place a high risk classification on those five locations, Brisbane, Logan, Moreton Bay, Ipswich and Redlands," he said.

"What that means, if you are in one of those local government areas now you cannot travel to Tasmania. If you do arrive in Tasmania, you will be placed into hotel quarantine for a period of up to two weeks.
"This will remain in place for the next three days and we will obviously take public health advice on when that will be lifted."
Mr Gutwein said they would be guided by Queensland authorities.
He said any Tasmanian returning from any of those five local government areas would need to quarantine and Public Health would provide further details on quarantine requirements.
