WA will introduce a hard border with Queensland from midnight after a highly contagious UK coronavirus strain was detected in Brisbane.
The change will come into effect from 12.01am on Saturday, WA Premier Mark McGowan announced on Friday.
“We cannot sit back and wait and watch. Given the number of contacts and potentially affected locations… we need to move fast,” he said.
People who have recently arrived in WA from Queensland will be allowed to return home, Mr McGowan said.
Queensland travellers coming to WA after midnight will only be allowed in if they have a special exemption.
Around 1,400 people from Queensland on nine flights are expected to land in Perth on Friday.
Mr McGowan said they will be tested and required to go into quarantine.
