An international ship carrying 16 crew members suspected of having COVID-19 has docked in Fremantle.
A Health Department statement said a plan for the management of the vessel would be made after test results were received on Tuesday.
Bulk carrier Ken Hou, which is sailing under the flag of Panama, came from Thailand, not Indonesia like previous COVID-infected ships.
Thailand has been scrambling to curb the spread of the Delta strain of COVID-19 in the community since April after faring reasonably well compared to other Asian countries during the earlier months of the pandemic.
The country surpassed one million cases last week, with authorities reporting almost 20,000 new infections and 240 deaths on Friday. To date, almost 10,000 Thai people have died from the virus.
“It’s different to the other ships we’ve experienced but we’re currently dealing with that issue,” Mr McGowan said on Sunday.
“We’ll assess her in Fremantle when she gets here, but we’ll do everything we can to keep our state safe.”
International ships have long been a blight in the McGowan government’s COVID-19 strategy.
