The friend who he was staying with has now also tested positive.
The 54-year-old man arrived in Perth from Shanghai, China, on April 3 and left hotel quarantine on April 17, after testing negative to COVID-19 on his Day 12 test.
He then stayed with a friend and her family in the Perth suburb of Kardinya and visited various locations including a restaurant, a swimming pool and a university college before flying to Melbourne on April 21.
Premier Mark McGowan said one of the people he had been staying with has returned a positive COVID-19 test, with health authorities still awaiting results from other family members.
Places of worship, pubs, clubs, bars, gyms, cinemas, entertainment venues, libraries and outdoor recreational facilities are shut down.
Cafes and restaurants can provide takeaway only.
Masks are mandatory for everybody over 12.
No visitors are permitted in hospitals or aged care. Weddings and funerals can go ahead, but with a 100-attendee capacity.
Residents living outside the restricted Perth and Peel regions are only allowed to enter to provide essential services or if they are returning residents.
“I encourage everyone to take part in the driveway dawn service again this year, and I will do that again,” he said.
“We will monitor this very closely here on and continue to assess the situation as more information comes to light.”
All passengers on board the flight the Melbourne man caught from Perth – Qantas flight QF778 – have been deemed close contacts and directed to self-isolate for 14 days.
It brings the total number of locally-acquired cases associated with the hotel outbreak to four.
The original pair that sparked an investigation by WA health authorities – a mother and her young child – tested positive on April 16 while still quarantined at the Mercure Hotel.
Mr McGowan said there were 16 others staying on that floor of the Mercure Hotel during the danger period, 13 of whom have so far returned negative test results.
The premier has requested Prime Minister Scott Morrison reduce WA’s international arrivals cap from 1025 a week to 512 a week for the next month.
