Three new COVID-19 cases have been recorded in Western Australia as Premier Mark McGowan continues to resist reopening the interstate border.
The trio tested positive after returning from the UK, the Middle East and India respectively. One has been hospitalised and the other two are in hotel quarantine.
WA has become increasingly isolated in its refusal to even set a date for bringing down its hard border.
All other states and territories have committed to reopening by Christmas with the use of defined hotspots to mitigate potential outbreaks.
South Australia has committed to lifting its border restrictions with NSW from midnight on Wednesday, removing the requirement to isolate for 14 days.
The decision came after two weeks of no community transmission in NSW involving cases with an unknown origin.
Mr McGowan remains adamant that WA's border won't reopen until NSW and Victoria go 28 days without community transmission.
"Our measures are working. Keeping COVID out, having a hard border and getting our economy back up and functional within the borders is working," he said on Tuesday.
"The price is that you can't freely travel to the other states and I note other premiers are critical of that. But other premiers don't have our record.
"Other states have COVID outbreaks and have had them now for seven months. We haven't had any for five months."
Despite a steady stream of returning travellers testing positive, WA has not had any known community transmission since mid-April.
Mr McGowan has repeatedly pointed to serious outbreaks in Europe and the United States when asked to justify his hardline stance despite the number of domestic cases continuing to fall.
Queensland recorded no new cases of coronavirus on Tuesday while NSW had just two, both of whom were returned overseas travellers in hotel quarantine.
In Victoria there were 28 new cases with the state's 14-day rolling average and number of cases with no known source both down on the day before.
Queensland has added five more northern NSW councils to its border bubble while Tasmania is considering reopening to some states next month and the Northern Territory is offering interstate travellers incentives to visit the Top End.
