Pellowe Reef

Pellowe Reef is a small isolated reef located close to the edge of the continental shelf. For this reason, access to the reef is weather dependent and best visited on fine weather days. The reef drops away to 30 metres very quickly in places, providing some spectacular diving. 

This reef offers divers an exciting wall dive and swim throughs. The majority of the dives will be in depths between 5 to 30 metres. Being closer to the continental shelf increases the possibility of large pelagic fish species along with the more regular sightings of chevron barracuda and nudibranchs.
