The second man who came through South Australia has returned to Victoria and Mr Dawson said authorities were helping WA Police locate him.
About 18,000 people were allowed into WA from other states in the week leading up to the grand final, with 500 applications for G2G passes rejected.
WA’s Health Department and police were also notified at 1pm on Tuesday afternoon that a Russian Antonov aircraft en route to the state from Queensland had a positive COVID-19 case on board, believed to be a foreign military crew member.
All 21 people on the plane have been put in hotel quarantine for 14 days.
Mr Dawson said the third emerging COVID-19 threat was in a ship travelling from Singapore, the Cayman Island-flagged Stolt Sakura, which has 11 out of 22 crew members so far testing positive to the virus.
The ship left Singapore earlier in September with some crew members reporting COVID-19 symptoms on Sunday.
Mr Dawson said all the different COVID-19 threats were a demonstration West Australians needed to get vaccinated.
“If people in WA don’t think that COVID is going to get here and they don’t need to get vaccinated, they’re kidding themselves,” he said.
“You’ve got a foreign vessel coming in, a foreign aircraft coming in, and then Australians who we allege are breaking the rules. And they think that COVID is not going to get here.
“We’re living with such freedom that I’m certain is the envy of others, but that will very quickly evaporate if COVID arrives.
“At the moment we’ve got about four out of 10 people that have not yet received their first vaccination … don’t be like a lackadaisical and apathetic about this, you’ve got to get vaccinated. It’s our only way to get through this pandemic.”
