Trigg, WA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Trigg is a relaxed beachside suburb of Perth, in the City of Stirling, named after Henry Trigg, who served as Superintendent of Public Works for the Swan River Colony in 1842. Land here was first taken up in 1877, though the suburb did not begin to develop in earnest until the late nineteen-forties, when its streets were named after early residents and local pioneers. The suburb is best known for the ocean. Trigg Beach is one of Perth's favourite spots for surfing and bodyboarding, with a reliable break that draws board riders year round, while the calmer waters of Mettam's Pool to the north are a popular place to snorkel. A coastal nature reserve and the shady, family-friendly Clarko Reserve add to the appeal of this breezy stretch of coast.
