Mandurah is Western Australia's second-largest city and one of the fastest-growing, sitting on the Peel Inlet and Harvey Estuary about 75 km south of Perth. The estuary system is the city's defining feature — a large, calm body of water that supports the dolphins which are commonly seen in the canals and waterways threading through the suburbs. Crab fishing is a local obsession, and blue manna crabs are caught in season throughout the estuary.
The city has a long surf beach on the ocean side and a sheltered waterfront along the estuary, with a reasonable concentration of cafes and restaurants around the Mandurah Foreshore. It's primarily a residential city for people who commute to Perth by train, but the dolphin tours and the estuary landscape make it a pleasant half-day excursion from the capital.
