The Cod Hole, off Port Douglas, north of Queensland, is a popular place to
Scuba Diving in Australia

Peter Stone, author of “Diving Australia” says this is a magnificent dive. Here’s part of his story…

‘We could see the huge Potatoe Cod lazily cruising near the bottom. Although we were on the inside of the reef, the visibility was at least 30m. Soon after we anchored several Cod came to the surface, obviously in anticipation of what was to come. The first snorkellers in the water made a hasty retreat as we were warned that the cod can be rather aggressive – enthusiastic would be a better description. Skipper Barry May gathered up scraps of food kept from previous meals. We went down. The cod came in – at least 20 of them – all jostling and heaving to get to the bin. Geoff the divemaster, was knocked about unmercifully but we didnt mind to much as it made for excellent photography.’

Special tours are available to view this annual wonder, if you are lucky enough to get the timing
