Trigg Island is a low wave-washed rocky islet that forms the northern boundary of the long Swanbourne to Trigg beaches. This northern part of the Perth coast was only developed in the 1950s, with the Trigg Island Surf Life Saving Club being established in 1954. In its first two years of operation it rescued 47 people from the more hazardous surf at this end of the beach.
The large surf club and adjacent restaurant is located 100 m south of the island, and has extensive car parks to either side. A watch tower also fronts the club, while Western Australian Surfing has its headquarters immediately south of the club house. The beach to the south of the club is called South Trigg. The surf club patrols the northern 1.5 km of the beach including the infamous Blue Hole, a permanent rip that runs out on the south side of the island, and has been the scene of many rescues. Furthermore, like adjoining South Trigg and Scarborough beaches, waves are higher along Trigg Beach, and the continuous bar is more likely to be cut by rips and rip channels, making this one of the most hazardous beach in the Perth region.
