Engelbrecht Cave – East

Meet the site

Engelbrecht Cave is the cave dive under a city: the doline sits in the middle of Mount Gambier on Chute Street, and its two flooded passages run east and west beneath houses and the Jubilee Highway. The site is named after Carl Engelbrecht, a German settler who in 1885 turned a nearby flour mill into a whisky distillery and used the cave for waste disposal. It was explored by canoe in 1864, bought by council in 1929, sealed in 1940, investigated by divers in 1964, cleaned up by the Lions Club in 1979, heritage-listed in 1995 and, since 2024, opened for guided dry tours with a café, viewing platforms and toilets.

The East passage is the Cave-rated half. From the lake it runs roughly 70 m, with a maximum depth of about 8 m, along a low, flat, silty passage that leads to an inner air chamber with its own lake, plus side passages and two further sumps of roughly 10-20 m each. It is shallow, intimate and relatively short, and the challenge is not depth or distance but silt: the floor lifts at the slightest disturbance, and the ceiling is close enough that trim and frog kicks are essential. Divers enjoy surfacing in the inner air chamber – an eerie, still room far from daylight beneath the town.

For newly rated CDAA Cave divers it is one of the most useful sites in the region: close to accommodation and fills, simple key access, fixed hours of 8 am-8 pm, and a passage that rewards good technique. Beyond the East passage lies the Advanced Cave-rated East Extension, which has its own row and rules, and the West passage is covered separately.
