Western Australia could maintain border checks and tracking of anyone who enters the state even after the COVID-19 pandemic, Premier Mark McGowan says.
The premier revealed his hardline stance on Tuesday after casting an early vote in his Rockingham electorate ahead of the March 13 poll.
With WA's hard border regime leading to a dramatic fall in methamphetamine importation, Mr McGowan is not ruling out enforcing the continued use of the G2G tracking pass.
Such a move would further differentiate and potentially isolate WA from the rest of the nation.
"The police commissioner and I will continue to talk about what can be done to protect the state from the scourge of meth and other drugs and if necessary, we'll look at measures we can bring in should we be re-elected," he told reporters.
"It's actually been remarkable, the reduction in drug usage in Western Australia, and that's because of the measures we've put in place. And that is a good outcome."
Mr McGowan said health advice would continue to be the overwhelming deciding factor in whether to keep borders open or closed.
Travellers crossing the border at Eucla and Kununurra are already subject to vehicle checks to prevent them bringing in fresh fruit and vegetables.
"If staff are there checking for bananas, tomatoes and avocados, I don't think it's unreasonable to have other staff there checking and stopping meth, heroin and cocaine," he said.
"Meth is a threat to people's health and we've had a 25 per cent or thereabouts reduction in meth usage, so obviously some of the things we've put in place have worked."
WA reported no new COVID-19 cases overnight. Almost 3000 people have received their first dose of the Pfizer vaccine.
Travellers from Victoria are required to quarantine for 14 days upon arrival, a measure that will be reviewed by the chief health officer in coming days.
