About Gouldens Sinkhole
Gouldens Sinkhole is a limestone freshwater sinkhole in South Australia used for cave-training dives by qualified divers and students. It is a surface-entry training site with cold thermocline layers, sparse freshwater life, and a tightly controlled booking process, so the site is better understood as a disciplined overhead-water exercise than as a casual recreational lake dive.
