Several new low-risk exposure sites have been identified in Perth and the South West.
It comes after three local cases were reported on Monday, which were the same cases announced on Sunday afternoon.
"Two are linked to the Cockburn cluster and the third is a known close contact of a previously reported case," a WA Health Department spokesperson said.
"One of three local cases was not in quarantine for their entire infectious period.
"Contact tracers are working with this case to determine potential exposure sites."
New exposure sites include the RAC Karri Valley Resort in Beedelup, the visitor centre, IGA and Coles in Margaret River and the Mammoth Cave in Forest Grove.
People who visited these exposure sites should monitor for symptoms and get tested if symptoms develop.
