Looking north from Cape Peron, south of Perth
For residents of NSW's Greater Sydney used to distinctive sandstone headlands separating their beaches, the seascapes around Perth come as a surprise. That's primarily because much of Western Australia's coastline has been carved out of limestone, creating landforms quite unfamilar to 'east coasters'.
While the limestone outcrops can be attractive, especially around Point Peron, south of Perth, they lack the upstanding stature that 'east coasters' are used to.

Offshore islands just south of Point Peron
One of the most interesting feature of the limestone coastline are the offshore islands that in bygone days proved to be devastating natural hazards to sailing ships bound for Melbourne and Sydney that strayed too close to the mainland.
Limestone formation at Two Rocks, Perth's most northerly suburb
North of Perth's CBD, limestone landforms continue to dominate the seascape, including at Two Rocks, a rapidly expanding suburb that was originally named for its twin limestone outcrops.
Two Rock's man-made harbour provides shelter for local boats.
Anyone who visits Rottnest Island immediately understands why it is such a popular holiday destination for Perth-ites and Western Australians in general. Limestone comes into its own on Rotto as these photos clearly show.
