Янчеп: История и современность прибрежного пригорода Перта.

Yanchep is an outer coastal suburb of Perth, Western Australia, north of the Perth CBD. It is a part of the City of Wanneroo local government area. Originally a small crayfishing settlement, it was developed by entrepreneur Alan Bond in the 1970s for the 1977 America's Cup. The area covers the urban centre of Yanchep as well as Yanchep National Park in its entirety.

Yanchep is bounded to the north west by Two Rocks and to the south by the rural localities of Eglinton, Carabooda and Pinjar. The non metropolitan Shires of Gingin and Chittering surround Yanchep's northern and eastern boundaries. West of Yanchep is the Indian Ocean. For a suburb it is extremely large, covering over and taking up almost the entire northern and north eastern portion of the City of Wanneroo. Despite this, Yanchep's urban concentration is almost entirely located in an enclave generally centred around the intersection of Marmion Avenue and Yanchep Beach Road, near the coast.

For thousands of years prior to the arrival of Europeans, the Yanchep area was inhabited by the Indigenous Australian Noongar people, and was a noted hunting site. The name Yanchep was adapted from the Noongar word "Yandjip", or "Yanget", which is their name for the bulrush reed that is common in the wetlands of the area. Following British settlement, the land now occupied by Yanchep was being used as a sheep station. In 1970, Alan Bond bought approximately of land at Yanchep and Bond Corporation developed designs for "Yanchep Sun City" a future satellite city of over 200,000 residents. The first houses in the area were built in 1972, and the marina at nearby Two Rocks was built as part of the same project two years later. However, sales of homes in the area had already slowed down by 1974. In 1977, the project was bought out by Tokyu Corporation after Bond Corporation began experiencing financial difficulties. In the Western Australian State Government's "Directions 2031" urban expansion plan, Yanchep was once again highlighted as a future satellite city and major metropolitan centre. The Smorgon family is developing the north coastal area Capricorn Beach as a planned development. On 11 December 2019, a fire that started in Yanchep burnt over several days through about 14,000 ha across Two Rocks and into the Shire of Gingin. Approximately 6,000 homes were saved, with only one being lost. The original Yanchep petrol station, owned by local Yanchep residents, was destroyed in the fire. The once thriving small business has been referred to as an icon of old Yanchep.
