Tourist cave in Mount Gambier. Dive begins in a small crescent of water which is often polluted by a nearby drain. Entrance restriction leads to a 90-metre long flooded passage which opens into a huge air chamber. Several other flooded passages run off making up roughly another 200 metres of passage in total. The main north-western passage ends in a small air chamber some 340 metres laterally from the entrance.
