Karst is a topography formed from the dissolution of soluble carbonate rocks such as limestone, dolomite, and gypsum. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. More weathering-resistant rocks, such as quartzite, can also occur, given the right conditions.
The Kanangra-Boyd National Park is a protected national park that is located in the Central Tablelands region, west of the Southern Highlands and Macarthur regions, in New South Wales, in eastern Australia. The 68,660-hectare (169,700-acre) national park is situated approximately 180 kilometres (110 mi) south-west of Sydney and is contiguous with the Blue Mountains National Park and the Nattai National Park. The park was established in 1969.
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet. A cenote is a type of sinkhole that exposes groundwater underneath. Sink and stream sink are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock.
A subterranean river is a river or watercourse that runs wholly or partly beneath the ground, one where the riverbed does not represent the surface of the Earth. It is distinct from an aquifer, which may flow like a river but is contained within a permeable layer of rock or other unconsolidated materials. A river flowing below ground level in an open gorge is not classed as subterranean.
Camooweal is an outback town and locality in the City of Mount Isa, Queensland, Australia. The locality is on the Queensland border with the Northern Territory. In the 2021 census, the locality of Camooweal had a population of 236 people.
Formed in 1956, the Australian Speleological Federation Inc. (ASF) is the national body representing those interested in the protection and sustainability of Australia's cave and karst environments. It has approximately 850 members across 28 constituent bodies throughout all Australian states and territories.
The Wombeyan Caves are caves that have formed in marble, in the Wombeyan Karst Conservation Reserve, New South Wales, Australia. Wombeyan Caves is a tourist attraction and local holiday area, as well as a reserve for endangered species, such as several species of wallaby, bird, possum, and wombat.
The Jenolan Caves are limestone caves located within the Jenolan Karst Conservation Reserve in the Central Tablelands region, west of the Blue Mountains, in Jenolan, Oberon Council, New South Wales, in eastern Australia. The caves and 3,083-hectare (7,620-acre) reserve are situated approximately 175 kilometres (109 mi) west of Sydney, 20 kilometres (12 mi) east of Oberon and 30 kilometres (19 mi) west of Katoomba. Dating back to 340million years ago, it is the oldest known and dated open cave system in the world.
Buchan is a town in the east Gippsland region of Victoria, Australia. The town is situated adjacent to the Buchan River, in the Shire of East Gippsland, upstream from the river's junction with the Snowy River. At the 2011 census, Buchan and the surrounding area had a population of 385. The town is most well known for the limestone Buchan Caves.
The Victorian Speleological Association Inc. (VSA) was created in 1967 by the merger of the Victorian Cave Exploration Society (1957) and the Sub Aqua Speleological Society (1960). It is a member of the Australian Speleological Federation (ASF) which is in turn part of the International Union of Speleology. The Association aims to explore and chart the extensive cave systems in Victoria (Australia) and elsewhere, represent the interests of Victorian cavers to the relevant authorities and to encourage the preservation of caves in their natural state. There are over 800 caves in Victoria, many of them on private property. In addition to its exploration, campaigning and conservation work the Association's members oversee recreational expeditions underground for the general public.
The Nambung River is a river in the Wheatbelt region of Western Australia, 170 kilometres (106 mi) north of Perth. The river drains an area between the towns of Cervantes and Badgingarra. In its lower reaches the Nambung River forms a chain of waterholes in the Nambung Wetlands where it disappears underground into a limestone karst system 5.5 kilometres (3 mi) from the Indian Ocean.
Agnes Milowka was an Australian technical diver, underwater photographer, author, maritime archaeologist and cave explorer. She gained international recognition for penetrating deeper than previous explorers into cave systems across Australia and Florida, and as a public speaker and author on the subjects of diving and maritime archaeology. She died aged 29 while diving in a confined space.
Little Blue Lake is a water-filled sinkhole (“cenote”) in the Australian state of South Australia located in the state's south-east in the locality of Mount Schank about 20 kilometres (12 mi) south of the municipal seat of Mount Gambier. It is notable locally as a swimming hole and nationally as a cave diving site. It is managed by the District Council of Grant and has been developed as a recreational and tourism venue.
Fossil Cave (5L81), formerly known as The Green Waterhole, is a cave in the Limestone Coast region of south-eastern South Australia. It is located in the gazetted locality of Tantanoola about 22 kilometres north-west of the city of Mount Gambier, only a few metres from the Princes Highway between Mount Gambier and Millicent. It is popular with cave divers and is notable for being both a unique paleontological site and the "type locality" for very rare crustaceans which to date have been found only in caves and Blue Lake in the Mount Gambier region.
The Cliefden Caves is a heritage-listed geoheritage site in Mandurama, Cowra Shire, New South Wales, Australia. The caves comprise Ordovician fossil localities, limestone caves, a spring and tufa dams, and a site where limestone was first discovered in inland Australia.
Cave diving is underwater diving in water-filled caves. The equipment used varies depending on the circumstances, and ranges from breath hold to surface supplied, but almost all cave diving is done using scuba equipment, often in specialised configurations with redundancies such as sidemount or backmounted twinset. Recreational cave diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves planned decompression stops. A distinction is made by recreational diver training agencies between cave diving and cavern diving, where cavern diving is deemed to be diving in those parts of a cave where the exit to open water can be seen by natural light. An arbitrary distance limit to the open water surface may also be specified. Despite the risks, water-filled caves attract scuba divers, cavers, and speleologists due to their often unexplored nature, and present divers with a technical diving challenge.
