After days of uncertainty, Western Australia will reopen its borders to NSW.
WA is scheduled to open up to NSW and Victoria from Tuesday, dropping the 14-day quarantine requirement for travel from those states.
However, an outbreak of coronavirus in NSW, Premier Mark McGowan took the weekend to receive further test results.
No locally acquired cases have been detected after a Sydney quarantine hotel cleaner caught the virus at work.
Another potential threat emerged over the weekend when two German travellers managed to avoid quarantine upon landing in Sydney and instead boarded a flight to Melbourne.
The pair have since tested negative to the virus and NSW police have accepted responsibility for the bungle, which forced the entire plane into self-isolation.
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 is significant for many Australians separated from loved ones with Christmas around the corner.
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.
