Waves are usually very low to calm at the shore. The beach itself is eroding into the backing pindan scarps and is backed by several seawalls and crossed by low rock groynes. At high tide the beach is narrow and awash, while at low tide it is fronted by tidal sand flats up to a few hundred meters wide. The township of Onslow, including the Bindi Bondi aboriginal community, back the beach, together with a road out to the creek.
