Dive briefing

AI-generated

This advanced wreck in open water reaches 28 metres at its deepest. Today's forecast shows a raw wave height of 0.6–1.0 metres and a period of 3.7–4.5 seconds, with sea temperature 21.3–21.5°C. The site rating is poor: conditions start decent in the morning but deteriorate during the ride-home window, which will affect your day.

Divers commonly log Napoleon wrasse, yellow spotted trevally, sixband angelfish, and longfin batfish here, along with groupers, giant trevally, and snapper species. You'll be diving an exposed site on open sand, so plan your boat window carefully and brief your team on the expected sea state change as the day progresses.
