Old Faithful is a rock wall and pinnacle formation off Camden Haven that has earned its reliable-sounding name through consistent, dependable diving over the years — a large cave at the base of the pinnacle is the site's headline feature, its interior supporting a genuine sponge garden that ranks among the better macro diving spots in the wider Port Macquarie and Camden Haven area. That sponge garden is significant enough to support the rare and much sought-after eastern blue devil fish, a species that draws dedicated fish-spotters and photographers specifically to sites known to hold it, making Old Faithful a worthwhile target for divers building a life list of unusual Australian reef fish. Beyond the cave and its macro life, the site supports jewfish schools moving through the open water around the pinnacle, along with a general scattering of pelagic visitors typical of this offshore reef cluster, and starfish and nudibranchs add further interest for divers with a slower, close-focus diving style.

The site's depth range of ten to twenty-five metres keeps it within solid recreational limits while still offering enough vertical structure to feel like a genuine pinnacle dive rather than a flat reef. As with the neighbouring Yabbies and Mermaid Reef, Old Faithful is a calm-weather, special-trip site rather than a daily fixture, and it rewards patient, detail-focused divers more than those chasing big-animal drama, with the eastern blue devil fish sighting typically the highlight any visiting diver hopes to tick off. Photographers hoping for the blue devil in particular should ask the skipper how recently it was last seen before committing gas and time to a thorough search of the cave.

Boat only, from the Camden Haven/Laurieton ramp or a Port Macquarie charter, in the same offshore pinnacle cluster as Yabbies and Mermaid Reef.

This stretch of coast is exposed to easterly and south-easterly swell with limited natural shelter; charters want under about 1.5 m swell and moderate wind to run safely. Visibility is best in autumn and early winter after a run of settled weather and drops noticeably after East Coast Lows and river flood outflows.

Descend onto the pinnacle's upper section around 10 m and work down to the large cave at its base, exploring the sponge garden along the way for the rare eastern blue devil fish and nudibranchs, then check the open water for jewfish schools and passing pelagics before ascending.

Scuba Haven (Port Macquarie) — regular boat dives, year-round, weather permitting.
