UPDATE: Popular tourist hotspots in the South West have been listed as new COVID exposure sites.
Areas of concern include the Busselton Pier and Information Center and the Cape Naturaliste Lighthouse.
Meelup Beach car park in Dunsborough has also been added, as has Eagle Bay.
Cowaramup and Gracetown also have gas stations and parking lots on the list.
Exhibition dates vary from December 21 to December 30.
All sites require people to monitor for symptoms unless otherwise advised by the Department of Health.
Late Sunday afternoon, other exhibition sites were also added to the list. Latest exhibition sites include Spudshed Spearwood, BP Kardinya and several Murdoch University buildings.
The Mekan Chargrill and Kebabs in Myaree has also just been listed. Anyone who was there on December 30 between 1:15 p.m. and 2:15 p.m. should get tested immediately.
It comes a day after a backpacker was arrested in Margaret River after flouting quarantine instructions.
The accused attended the Perth Mess Hall event and had to self-isolate for 14 days.
The man and his girlfriend were arrested by police on Tanah Marah Road and quarantined at the hotel.
Police Commissioner Chris Dawson said a number of Perth Mess Hall revelers ignored instructions.
“As we know there were over 400 people at the Perth Mess Hall and not all of them came forward of their own free will,” he said.
Premier Mark McGowan had said some of them even turned off their phones and tried to avoid police and contact tracers.
Others added fake phone numbers and contact details and could not be traced.
Police are still looking for a number of close contacts linked to the backpacker who sparked the Perth Delta outbreak before Christmas.
Although the virus has spread in the South West, Mr McGowan has not enforced restrictions in the region.
Only Perth and Peel are subject to mask mandates and closures of nightclubs and festivals.
