WA has entered a five-day lockdown after recording a case of COVID-19

At an emergency press conference on Sunday afternoon, WA Premier Mark McGowan announced a male security guard aged in his 20s who had been working at Sheraton Four Points in the CBD had tested positive for COVID-19, and spent a number of days in the community.

He confirmed that returning travellers carrying both the UK and South African mutations of COVID-19 were quarantining at the hotel where the security guard worked, but did not reveal which strain the security guard had.

"The measures will start from 6pm this evening... I just urge people to be sensible and do the right thing.There is no need to rush to the supermarkets. They will not be a shortage of toilet paper or other goods. You will be able to go out and shop for essentials over the course of this week. I urge everyone to remain calm and to act responsibly." - WA Premier Mark McGowan, speaking on Sunday.

All residents must stay home unless for four activities: shopping for essentials, attending to medical or healthcare needs, exercising within their neighbourhood or working if unable to do so remotely.

Schools will remain closed for another week. They had been due to resume today.

WA had gone nearly 10 months without a virus case in the WA community.
