About Bateman Bay
Mantas circle a series of cleaning stations on bommies in 10-15 metres of water, drawing reef cleaner wrasses to remove parasites. Encounters last as long as the divers stay still. Peak season is May through October when mantas aggregate in groups of up to a dozen. Reef structure is moderate but the marine megafauna access is the draw. Boat-only access via Exmouth charter operators.
