Western Australia is set to double its international arrivals cap to 530 people per week when 70 per cent of the eligible population is fully vaccinated.
The state is expected to surpass the milestone on November 20.
Currently, 66.8 per cent of the population is fully vaccinated.
All international arrivals must quarantine for 14 days in a state-run facility at their own expense.
Returning travellers will be subject to regular mandatory testing during and after their quarantine period.
