Blue Devil Cave at Bass Point is a shore dive featuring a small cave system and surrounding reef. Divers can explore depths ranging from 3 to 22 metres, with visibility typically between 9 and 13 metres. The site is sheltered from most winds, resulting in mild currents. The cave creates an overhead environment, and surge can be present near the entry and exit points, which may be challenging during high tides. Marine life recorded at the site includes Eastern blue devilfish, wobbegong sharks, wrasses, sea hares, sea stars, snails, and nudibranchs such as Jorunna Nudibranch and Clown Doris.

Visit between June and November for the best chance of spotting blue devilfish, which are more reliably present in the cooler months. Surge can push you around near the cave entrance, so time your entry between sets and keep a hand free to steady yourself on the way in.
Access is via the shore entry point known as "The Gutter" in the Bass Point Reserve, south of Shellharbour. Park in the designated car park and walk across the grass and rock platform to the entry point. The cave is approximately a 150-metre swim from the entry.
