Coastline features[edit]

The coastline is approximately 24 kilometres (15 mi) long. Bays, points, reefs and smaller islands along this coastline are extensively named.


The named hills of Rottnest are Oliver Hill, Radar Hill and Mount Herschel, and the main lighthouse of the island is known as Wadjemup Lighthouse.

Named lakes[edit]

Wells and bores[edit]

The island is very limited in water supply and considerable numbers of bores have been sunk to keep water supply available.[4]

In 1976, Philip Playford's Geological Map of Rottnest[5] identified wells, abandoned wells, and bores on the island. The following is only a select list of the full range.

West end[edit]

  • Radar Hill just east of Cape Vlaming had Radar Station Well and was designated "abandoned".

South coast[edit]

  • Parker Point between Salmon Bay And Porpoise Bay, had Parker Point Bores as "abandoned", closer to Tree Hill the well and bore were active.
