More than 60 tonnes of sand has been dumped in the middle of Perth, bringing the beach to the city this summer.
Paddling pools, mini beach huts, deckchairs and colourful umbrellas will set the scene at the Perth cultural centre when the pop-up beach is launched tonight.
An initiative by the Metropolitan Redevelopment Authority, the venue will celebrate summer in the city with a program of events well into January.
MRA executive director of place management Veronica Jeffery said the innovation was a way to activate space and draw people into the centre.
"It's about bringing something new and exciting into an existing space and creating new interest," she said.
"With all our pop-up initiatives throughout the city we want to promote Perth as an ever-changing place where new experiences can be had all the time."
The venue will feature live entertainment, beach beats and retro movies on the big screen - diving in with classic 1950s film Gidget tonight.
Next Friday brings the return of the Illuminates Festival, with pop-up night markets for food, gifts and all things Christmas.
Ms Jeffery said Perth's newest beachside venue would be serviced by pop-up bars and food vendors and provide a relaxed atmosphere for anyone looking to enjoy a summer night in the city.
"It will have a real 1950s, retro feel and will be a place where you can come and relax after work or come with friends for a chilled evening in the city," she said.
The pop-up beach will be in place until January 19 before the Perth Fringe World Festival starts.
