Western Australia Premier Mark McGowan expects to receive updated advice on reopening its borders to Victoria and NSW this week, as both states continue to stack up more days without a locally acquired COVID-19 case.
Victoria has already reached WA's criteria of 28 days without community transmission to qualify for eased border rules, while NSW has now gone 22 days without a locally-acquired infection.
Mr McGowan has been steadfast about not rushing into a decision, nominating the recently reopened NSW-Victoria border as a reason to take stock.
"NSW is not at 28 days yet and they have an open border with Victoria so we will just be risk-averse," he told reporters on Sunday.
"I know some people want to rush on this, but the vast majority of people just want to be cautious and careful and we will continue to be cautious and careful."
He expects to make further announcements during the week once briefed on the latest health advice by WA Chief Health Officer Andy Robertson.
"Clearly with NSW and Victoria, you've got to be careful," he said.
"They have had some of the worst COVID experiences in Australia. We want to make sure we are completely sure that it is the right time to change the border arrangement before we do so."
Under the current arrangement, travellers from Victoria, NSW and South Australia are required to quarantine for two weeks upon arrival in WA.
The bubbling border pressure came as a 42-year-old man was arrested and charged for breaching self-isolation in Perth after arriving from Adelaide almost two weeks ago.
The man was granted a permit to enter WA for work purposes and landed at Perth airport on November 16.
After being granted permission to relocate to Northbridge on Saturday from his initial Cannington base, police found him at a nearby licensed venue after a public tip-off.
He was charged and refused bail ahead of facing Perth Magistrates Court on Sunday.
Meanwhile, WA reported a solitary case of COVID-19 on Sunday among a returned traveller in hotel quarantine.
