Wellington Caves: A Journey Through Ancient Geology and Paleontology
The Wellington Caves region serves as a profound window into Australia's prehistoric past. Long before European arrival, the area was known to the Binjang mob of the Wiradjuri people, who called the caves Mulwang. Local tradition may have associated these subterranean spaces with a mythological spirit named Koppa. While direct evidence of the Wiradjuri entering the caves is absent, their knowledge of the entrances is well-documented.
The first European visual record of the site dates back to 1826, when artist Augustus Earle painted the entrance of what is now called Cathedral Cave, depicting Aboriginal people gathered around a fire.

Key Facts
- Indigenous Name: The Wiradjuri people referred to the caves as Mulwang.
- First Written Record: Provided by explorer Hamilton Hume in 1828.
- Major Fossil Finds: Remains of the Pleistocene-era Diprotodon and giant kangaroos.
- Reserve Status: Declared a natural reserve in 1884 to prevent vandalism.
- Cave Network: There are currently 26 known caves within the reserve.
Early Exploration and Paleontological Discoveries
Following the early visits by those associated with Lieutenant Percy Simpson's settlement (1823–1831), the caves became a focal point for scientific discovery. In 1830, local magistrate George Ranken discovered fossilized bones of a giant kangaroo and a Diprotodon—a large, herbivorous mammal from the Pleistocene period (the epoch preceding the current Holocene) characterized by teeth specifically adapted for grazing.
Ranken later collaborated with Sir Thomas Mitchell to collect a vast array of bones. The caves had functioned as a natural trap for fauna, preserving a biological record that Mitchell presented to the Geological Society of London in 1831. This legacy of research continued into the late 19th century, most notably through the work of Gerard Krefft, Curator of the Australian Museum, who conducted extensive excavations in 1866 and 1869.
The Evolution of Tourism and Mining
To protect the site from frequent 19th-century vandalism, the caves were declared a natural reserve in 1884. Shortly after, in 1885, organized tours of Cathedral Cave began under the management of the first caretaker, James Sibbald. The discovery of Gaden Cave in 1902, which was developed for visitors in 1909, further expanded the site's appeal.
The region also saw brief industrial use. Between 1914 and 1918, a phosphate mine operated on-site. Although the venture removed 6,000 tons of rock, the actual phosphate yield was limited. These mine passages remained dormant and collapsed for nearly 80 years until they were reconstructed and reopened for public tours in 1996.
Modern Speleology and Mapping
Since the late 1950s, the Sydney University Speleological Society (SUSS) has been instrumental in expanding the known boundaries of the reserve. Through speleology (the scientific study of caves) and specialized cave diving, SUSS members have mapped and discovered many of the 26 known caverns.
Significant modern discoveries include McCavity Cave and a subterranean lake located beneath Limekiln Cave. Additionally, the society successfully rediscovered Anticline Cave, which had previously been buried beneath the Wellington Caves Caravan Park.

Frequently Asked Questions
Who were the first people to know of the Wellington Caves?
The Binjang mob of the Wiradjuri people inhabited the region and called the caves Mulwang, associating them with a spirit named Koppa.
What is a Diprotodon?
The Diprotodon was a large, herbivorous mammal from the Pleistocene period. Its fossils, found in the caves, show teeth that were well-adapted for grazing.
How many caves are currently known in the reserve?
There are 26 known caves in the reserve, many of which were discovered or mapped by the Sydney University Speleological Society.
Was there ever mining activity in the caves?
Yes, a phosphate mine operated from 1914 to 1918, removing 6,000 tons of rock before closing. These passages were later reopened for tours in 1996.
When did public tours of the caves begin?
Organized tours of Cathedral Cave began around 1885, following the appointment of James Sibbald as the first caretaker.
