Perth and Peel residents will know by today whether the mask mandate will be lifted or if it's here to stay.
It comes after a household contact of an infected quarantine hotel security guard tested positive to COVID-19 on Thursday, sparking fears the rule of mask wearing indoors could be extended.
WA Health has released 13 more exposure sites including an Aldi, Repco and the Commonwealth Bank in Kwinana and Kmart and the Lottery kiosk at Rockingham Shopping Centre.
People who have visited those sites on the specified dates and times are asked to monitor for symptoms and if they do get symptoms, to get tested and isolate.
