Late on Thursday night contact tracers published 13 new potential exposure sites.
On Sunday morning between the backpacker’s visits to Northbridge nightclubs, Geisha Bar and Connections authorities also say he visited Thai eatery Bangkok Brothers.
Before his big night on Saturday the man visited several shopping centres and liquor store locations in Perth’s northern suburbs.
He also went on a lunchtime shopping expedition on Friday with a range of Perth CBD shops added to the list including JB HiFi at Enex 100 and the Vans shoe store in the Murray Street Mall.
In a statement, WA health said it was working to identify contacts and confirm more exposure sites.
Premier Mark McGowan said that casual contacts would be in the hundreds.
Early testing suggests the man has Delta variant.
The case has thrown Mr McGowan’s hopes of a normal Christmas in Perth into disarray with the Premier announcing the closure of major events and a mask mandate for indoor venues up to next Tuesday.
“We’re closing down all the music events … the Ice Cream Factory and various places, we’re saying over the next four days they won’t be happening,” Mr McGowan said.
Close contacts will have to isolate for 14 days and casual contacts must get tested and isolate until a negative result is returned.
Testing clinics were inundated with people on Thursday afternoon and Mr McGowan warned people to expect lines again on Friday.
The backpacker had been in Australia since early 2020.
