Western Australia is increasingly likely to proceed with reopening its borders within days after fears of a NSW coronavirus outbreak were allayed.
Premier Mark McGowan will reveal his decision on Monday, having taken the weekend to receive further test results from NSW.
No locally acquired cases have been detected after a Sydney quarantine hotel cleaner caught the virus at work.
WA is scheduled to open up to NSW and Victoria from Tuesday, dropping the 14-day quarantine requirement for travel from those states.
Another potential threat emerged over the weekend when two German travellers managed to avoid quarantine upon landing in Sydney and instead board a flight to Melbourne.
The duo have since tested negative to the virus and NSW police have accepted responsibility for the bungle, which forced the entire plane into self-isolation.
“It’s certainly not the gold standard,” Mr McGowan said, referencing a phrase used by NSW counterpart and political adversary Gladys Berejiklian to describe her state’s handling of the pandemic.
“It obviously shows that COVID is a risk and that’s why we continue to have a controlled border to ensure we can protect people into the future.”
Travellers from NSW and Victoria have been blocked from entering WA for almost nine months unless they went into quarantine and, until recently, secured exemptions.
The decision on whether to proceed with reopening the NSW border will be significant for many Australians separated from loved ones with Christmas around the corner.
It comes at a time when the federal government is urging Australians to travel across the nation in an attempt to help the struggling tourism industry.
The McGowan government is also set to review health advice this week regarding travel to and from South Australia, which remains subject to hard border restrictions after experiencing a cluster of locally-acquired cases.
