More than half of Australia's population is now banned from entering Tasmania, after the high risk classification of Greater Sydney by public health officials here was expanded to include all of NSW.
That state recorded over 100 new cases of coronavirus on Saturday and Sunday, with reports some are fleeing the Habour City lockdown to go to freer regional areas.
It's prompted the Premier to reimpose a hard border not seen since the start of the pandemic, meaning only those with an exemption will be allowed in.
"We have been through this before. None of us wanted to go back to a situation where we've got large parts of the country locked out of Tasmania," Peter Gutwein said.
The entire state of Victoria is also high risk, but it's hoped that won't last too long, with the snap 5 day lockdown there due to end on Tuesday.
16 new local infections have been recorded there in Sunday's daily figures - all linked to current outbreaks.
Deputy Director of Public Health Scott McKeown was visibly distressed while announcing the hard border to all of NSW and Victoria late yesterday.
"For a person to travel from that region...they will need to apply for permission to enter the state. We'll continue to monitor the situation and respond accordingly," Dr McKeown said.
