Perth nightclub owners are accusing the McGowan government of double standards after a vaccination backflip at last night's AFLW Derby.

Three days ago, the Dockers website was reminding fans over the age of 16 to provide proof of their double dose vaccination.

Nightclub owner Chris Patton from the Butterfly Club called the move "double standards".
He says the decision to remove proof of vaccination for 5,500 fans is unfair, when his industry has been impacted by its introduction.
"Northbridge has just been a ghost town, the people coming out are just confused, the legislation is just not clear enough that you need to be double vaxxed," he said.
"We're turning away one out of four or three people cause they're single vaxxed and you turn them away, their whole friend group leaves."
Infectious diseases expert Clay Golledge said the changing rules could see people "lose faith in the health advice".

A state government spokesperson told 9News "the Perth Cup is a different event to an AFLW match and took place a week ago under different restrictions and when the Delta backpacker outbreak was at a concerning stage."
There was one new case linked to the Perth cluster today, a close contact who has been isolating.
Further Omicron transmission in WA has been avoided for now, with 27 close contacts of the Hyatt Hotel case all testing negative.
