Western Australia will ease restrictions for people arriving from Victoria and NSW as the nation's COVID-19 case numbers continue to fall.
From next Monday, Victorian arrivals - who remain subject to tight exemption criteria - will no longer be required to enter hotel quarantine at their own expense.
They will instead be allowed to self-isolate at a suitable premise for 14 days.
People in NSW will also no longer be subject to tighter exemption criteria than those in other states.
"This is a positive step forward for our nation," Premier Mark McGowan said on Tuesday.
"We can make these adjustments to our border controls because of the positive results we have recently seen over east."
Victoria recorded 10 new cases and seven deaths on Tuesday, while two new cases were recorded in NSW.
Entry to WA from Victoria will remain limited to transport or freight and logistics workers, some politicians and military personnel and health workers.
They will continue to be tested upon arrival and on day 11 of their quarantine period.
Mr McGowan says he is still not prepared to set a date for reopening the hard interstate borders despite the continued decline in cases.
"We're not going to do so until we're completely sure we get the health advice that is completely safe," he said.
He confirmed the health advice remained that the hard borders should not reopen until the eastern states recorded 28 days of zero community transmission.
There has been no community spread in WA for almost six months.
The government has also launched a new G2G Now app allowing people in quarantine to check in and provide police with their location.
Mr McGowan says it will reduce the need for physical police checks and deliver certainty as a greater number of people enter self-quarantine.
