Tasmania is joining other states in declaring the Greater Brisbane area a Covid hotspot, in response to four new cases emerging in the Sunshine State, throwing holiday plans into disarray.
Greater Brisbane will enter a three-day snap lockdown from the close of business on Monday.
"Tasmania will, effective immediately, be putting in place a high-risk classification on those five locations: Brisbane, Logan, Moreton Bay, Ipswich and Redlands," said Premier Peter Gutwein on Monday morning.
"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 can be lifted."
One case has travelled to Gladstone in Central Queensland, while another two have crossed the border to Byron Bay.

"I didn't sleep last night, so I am very worried, I am very concerned," she said.
"We've done it before, we've got through this together, and I'm sure if everyone does the right thing we'll be able to get through it."
