The Mandurah Estuary, also referred to as the Peel-Harvey Estuary system, is a large, sheltered waterway in Western Australia encompassing approximately 134 to 136 square kilometres of calm inland waters. This extensive area is characterized by its protected and generally placid conditions, making it suitable for paddlers of all ages and skill levels, including those using canoes, kayaks, and stand-up paddleboards. A notable feature for accessibility is the recent installation of an all-abilities paddle launch, which includes custom slipways and special seating to facilitate safe entry and exit for a wide range of paddlers. The overall experience is focused on nature and wildlife, with opportunities to observe abundant birdlife while exploring the river systems. Guided tours, including private kayak excursions and specialized photography-focused trips, are available, with some operating during sunrise. The estuary supports multiple recreational activities alongside paddling, such as crabbing, fishing, and boating, and areas are available for picnics. The water body's significant size and interconnected waterways suggest numerous potential routes for day trips.
