Details

Club dive with St George Underwater Centre.

Entered water on north-eastern corner of island and headed to the south wall. Swam along the south wall for a while and then back along the wall.

At around 36 minutes into the dive the alarm for housing leak detector came on indicating there was water in the housing. I signalled to Bobby that it was time for an emergency ascent and we headed back to the edge of the island as quickly as possible. Fortunately, the camera did not get wet but I have to work out why the housing leaked.
