Cottesloe Beach Pylon, Heritage pylon at Cottesloe Beach, Australia.

The Cottesloe Beach Pylon is a concrete tower standing in the surf off Cottesloe Beach, square in plan and tapering slightly toward the top, with a white coating over its faces. It rises from the sand and rocks near the shore, and at low tide its base is exposed.

Built in 1936, the pylon is the surviving remnant of a shark-net scheme for Cottesloe Beach that was abandoned before the net was finished. It was entered on the State Register of Heritage Places in 2003. The concrete shaft has since become a fixed mark on the beachfront.

The pylon has served for decades as a reference point for beachgoers and has become a symbol of local community connection. People gather here, take photos, and use it to orient themselves while exploring the shoreline.

The structure is clearly visible from the shore and can be viewed from the beach, with especially good views during low tide conditions. Access to the immediate area is straightforward for swimmers and beachgoers without any special requirements.

The pylon was originally part of an ambitious shark protection fortification plan that was abandoned before full completion. This unfinished story makes it a curious remnant of an era that later opted for different safety methods.
