The state’s only new confirmed case of COVID-19 overnight is a 19-year-old woman who travelled overseas.
It brings WA’s total cases to 551 but only 43 remain active, including 15 from the plagued Artania cruise ship and two from interstate.
Fourteen COVID-19 patients are in metropolitan hospitals, including four in intensive care.
The WA government on April 29 announced a COVID-19 hygiene training assessment, which will be compulsory for the state’s 70,000 hospitality workers.
Anyone employed at a cafe, bar or restaurant, all of which are currently restricted to takeaway and delivery orders, must complete the free course before the establishments can reopen.

“I know the first question will be ‘Does this mean cafes and bars and restaurants are all about to reopen?’ No, it doesn’t,” he said.
“We still have to accept the medical and health advice in that regard.
“But we want to make sure that when they do reopen, we have the best and safest and healthiest environment available, and staff are protected and customers are protected as well.”

Schools began term two on Wednesday, with cleaning increased throughout the day as well as staggered starts, breaks and meal times to reduce contact.
