Pines Cave, AustraliaPines Cave is the most frequently dived cave in Mount Gambier, Australia. The cave is so called as it is located in the middle of a pine forest, next to an unsealed road, and at one time had single pine tree growing inside. The pine tree was cut down and the remains of the stump can be found by divers in the main cavern zone, after having fallen into the water and down the slope. The cave has deep passages, including a recently discovered chamber, which together doubled its volume. The cave has a small surface lake which quickly opens up to a large sloping chamber, with tunnels heading off in most directions, some having over 200 meters penetration from the surface, and up to 43m deep.
