Northern Territory

Australia’s last frontier and epitome of the American Wild West, the Northern Territory (NT). Not a lot is known about the cave diving potential of the Northern Territory, though there are extensive karst areas, just as there are in northern QLD and the Kimberleys of northern WA. Tolmer Falls is the kind of place that is hidden away in little oases around the Top End of Australia. There is good potential for new cave systems with diveable passage to be discovered.

It is intended that these pages become a repository for all information relating to the diveable caves in the NT, including descriptions, photos, video clips, maps and site access data-sheets. Please email TrimixDivers (use the email lighthouse) if you want more info, have additional information to share or want to be involved with future trips or expeditions.
