Fishery Beach at the very bottom of the Fleurieu Peninsula faces south west onto Backstairs Passage, one of the most perilous waterways in Australia.

If it’s not the 4 knot currents or claptopic seas then it’s the men in grey suits who prowl beneath the surface that make this part of our coastline unique.

But sometimes, just sometimes, it’s OK to dive here.
