The Mandurah Estuary and Peel Inlet cover an area twice the size of Sydney Harbour and are regarded as one of Australia's most spectacular playgrounds for boating, fishing and wildlife watching.
Mandurah is located less than an hour's drive or train ride south from Perth, making its 155 square kilometres of waterways easily accessible for a day trip or weekend break.
Take to the water by hiring a boat, houseboat, kayak, canoe or jet-ski, or hop aboard a cruise. A dolphin watching tour will also give you the chance to tick your bucket list - one of Australia's healthiest populations of wild dolphins can be found there.
Bird watchers will also delight in spotting some of the 130-plus species of birds that nest, breed and feed on the estuary.
The sheltered waters also provide a safe place to fish. Cast a line from the jetties or landings under the bridges to chase herring, sand whiting, bream and tailor.
Catch a meal of river prawns in early summer, fish for king prawns in autumn, or go crabbing during late summer and autumn to scoop the famous blue swimmer crab.
Or, for a bigger catch, join a deep sea fishing charter.
