Lancelin, north of Perth Western Australia, is a small tourist and fishing town with a permanent population of about 650 people which swells to about 2,500 during holiday periods. Holiday activities include surfing, windsurfing, kitesurfing, fishing, sandboarding and 4-wheel driving on the famous white sand dunes.  Although initially a holiday and camping place during the 1940's, it has now become an important base utilised by the crayfish or lobster industry. Dolphins regularly appear in Lancelin Bay to entertain visitors with their acrobatic displays. The offshore islands are conservation reserves where the inhabitants include colonies of sea lions.
