Genome sequencing is underway to determine the variant. WA Health has not released any new exposure sites yet.

In recent weeks, both the Delta and Omicron variants have been passed down locally in Perth through three known sources: a Queensland backpacker with Delta (23 cases), and a hotel security guard (3 cases) and Tasmanian traveler with Omicron (2 cases) .


A handful of interstate truck drivers have also transmitted the virus locally in recent weeks, but authorities claimed the risk of continued transmission associated with those cases was low and gave few details about the infections when questioned.

The mysterious case is the first in WA that cannot be linked to a known cluster since April 2020 and indicates that there is undetected transmission in WA.

It comes as Health Secretary Amber-Jade Sanderson said Tuesday it was likely that Omicron was spreading in WA, with other states recording tens of thousands of cases a day.

A second local case was registered overnight and is linked to the Hyatt Hotel’s security cluster, which now ranks three. The person was identified as a close contact and has been in quarantine during his contagious period.
