There are more than a dozen beaches just in the small area around the Labillardiere Peninsula alone, both north-facing and south-facing. If you look at them, there is a beautiful symmetry in their shape. ‘Catenary curves’ are the name given to a beautiful geometrical curve, and that is how beaches are shaped. This clearly demonstrates that there is a physical process going on related to the amount of energy, the type of material and so on, it is not just a random process.
Also the nearby rocks will shape the beach and its colour. A darker beach exists near a dolerite foreshore, for example. You can see this at the darker coloured East Cove beach just near the Fluted cape walk.
Not all beaches are sandy – we’ve got to get that message across too – there’s rocky beaches too, pebble beaches too, huge variety.
The two beaches on either side of the neck are both extraordinary in their own way, and highly contrasting in their ecology. Chuckle head, Little Fancy Bay, and Great Bay are also incredible. If you walk along that section of coastline, you can find a beach where millions of tiny shells have been deposited, so it’s a shell beach, and that’s relatively unusual in Australia.

It seems like such a simple question, “why does a beach have a curve on it?”. Yet even small beaches have a curve. This is because the energy of a beach is concentrated in the middle.
When a waves come in, there is an enormous amount of energy, but it loses that energy as it sweeps up the beach, dropping heavier particles first and then dropping the finer particles of sand.
Protecting beach birds is not just about focussing on where they might be when they’re breeding. Its about saying – “these birds occupy many beaches”.
There are two incredibly different coastal environments to the west and the east of the neck, as explained here by geographer and naturalist, Bob Graham
