Tregrosse Reefs features a dramatic wall that drops from recreational depths into the deep ocean. Divers can explore the reef structure between 5 and 30 metres, with an average depth of 18 metres. The site is accessible only by boat and is suited for intermediate divers. Visibility typically ranges from 15 to 30 metres, though it can reach significantly further. Currents are generally mild, but divers should be aware of potential surge near the wall. The habitat supports a variety of reef fish and invertebrates typical of the Coral Sea region. Proper decompression planning is essential due to the extreme vertical scale of the wall.

With visibility potentially hitting 100 metres, it is easy to drift deeper than planned while tracking the wall, so set a hard turn pressure and stick to it. Confirm local dive operator availability before making the trip, as facilities are not guaranteed on site.
Trips depart from Townsville at the Fuel Wharf, Mariners Drive, Breakwater Marina or Magnetic Island at the Nelly Bay Ferry Terminal.
