Great, milky tides surge into Yawuru Nagulagun Roebuck Bay Marine Park, drowning meadows of seagrass, submerging sandbanks and slabs of oxblood sandstone, and washing away cars carelessly parked on intertidal mudflats. The fast-rising currents swallow the hapless vehicles and regurgitate their rusted carapaces up and down the Dampier Peninsula.
This region is subject to one of the world's largest tidal fluctuations – a phenomenon which carries with it a rich brew of nutrients and the superfluity of marine life subsisting on them. Among the most unusual of these creatures is the Australian snubfin dolphin, a species largely unknown – even among those who live here.
