Whyalla is an industrial town on the southern coast of Australia. Every year, for a few months between May and August, Giant Cuttlefish arrive and congregate in a patch of shallow water just out of town. This is the only known gathering of large numbers of cuttlefish, and the results are a unique spectacle not replicated anywhere else.
It’s not known how far they migrate, or why they choose that particular area, but they have appeared reliably every year, in tens of thousands, along the same few miles of coast. They gather to reproduce; those months are a continual melee of courting, fighting, mating, and the laying of eggs, all accompanied by an unending chorus of color changes.
How deep is the water?
The cuttlefish aggregate in 2-6 metres of water along a six kilometre stretch of the Point Lowly and Black Point. Perfect for snorkeling.
This peninsula is 20 kms north of the city of Whyalla. The aggregating sites are accessible from shore.
