A Coles Express, Pizza Hut, 7 Eleven service station and KFC are among the locations that have been added to the COVID-19 public exposure sites list in Perth, as contact tracing continues.

The Perth and Peel regions still have some restrictions in place, including the use of masks in public, after a hotel quarantine security guard and two of his housemates contracted coronavirus.

Western Australia did not record any new cases overnight, either in the community or in hotel quarantine.

The Health Department said it was able to add some locations to its list of places visited by confirmed cases, as well as refine details for others, following further contact tracing and a review of CCTV footage.

New locations under the public exposure sites:

7 Eleven service station, 102 Princess Rd, Balga, April 28 from 7.45pm to 8.15pm
KFC Whitfords, 7P Cromer Grove, Hillarys, April 29 from 10.40pm to 11.15pm
