Tidbinbilla Nature Reserve

Tidbinbilla Nature Reserve is a 54.5 km2 protected area, on the fringe of Namadgi National Park. Tidbinbilla is a short drive from the capital city of Australia, Canberra, in the Australian Capital Territory.

The nature reserve consists of a large valley floor, the Tidbinbilla Mountain and the Gibraltar range. The sides of the valley are steep and relatively undisturbed. The lower slopes of the valley are partly cleared and have a significant history of Aboriginal and European use. Tidbinbilla Mountain is believed to have been used for Aboriginal initiation ceremonies. The word 'Tidbinbilla' is Aboriginal in origin and comes from the word Jedbinbilla – a place where boys become men.

Known sites of Aboriginal significance at Tidbinbilla include the Birriagi Rock Shelter, which is the oldest Aboriginal site within the Australian Capital Territory. Bogong Rocks is a shelter where the oldest evidence of Aboriginal occupation was found at a bogong moth resting site.

The nature reserve is classified as an IUCN Category II protected area. It is the traditional Country of the Ngunnawal people.

Indigenous history
Aboriginal people have inhabited the Tidbinbilla area since antiquity. Archaeological digs at Birrigai, over the hill from Tidbinbilla, found the earliest evidence of the use of fire, dated at 20,000 years old. This was at the time of the last ice age. Excavations at Hanging Rock has dated occupation of that site to some 16,000 years.

The name Tidbinbilla is derived from the Aboriginal word 'Jedbinbilla' meaning a place where boys become men. The last corroboree, an Australian Aboriginal dance ceremony, held at Tidbinbilla was circa 1904. There are aboriginal rock paintings to be found at Gibraltar Peak in a small cave.

European history
There are over 100 years of European occupancy within the nature reserve. Nil Desperandum and Rock Valley Homestead are both pise rammed earth buildings built in the 1890s. Both buildings were built by George Green and George Hatcliff. Nil Desperandum is a historic four-roomed residence alongside Hurdle Creek first occupied by Henry French Gillman. The remains of a commercial camellia plantation and the best preserved eucalyptus distillery in the ACT are also nearby.

The Rock Valley Homestead was occupied by the Green family. Nil Desperandum was later occupied by George Greens daughter Elsie Jane and her husband Eric Blewitt from the early 1930s to the early 1950s when Eric was killed drenching a horse.

Both Nil Desperandum and the Rock Valley Homestead buildings were severely damaged during the 2003 Canberra bushfires. Nil Desperandum has since been rebuilt in its original condition and design with the kitchen extension but not the enclosed side verandah that the two brothers John Douglas (Doug) & Cyril Leslie (Ned) both slept in.

History of the nature reserve
In 1936 about 8.10 km2 were set aside as a public reserve. In 1939 a koala enclosure was built by the Institute of Anatomy. The government acquired additional land to establish a national park and fauna reserve in 1962, extending the national park to 36.29 km2. Tidbinbilla was later expanded again to its current size.

In 1966 the park saw the appointment of park ranger and later manager, David Kerr. He developed many of the bush walking tracks, enclosures, water fowl areas and roads throughout the park. Under his management the Cape Barren goose enclosure and conservation scheme was developed which has significantly contributed to the survival of the endangered species. In 1969 the first wildlife displays were created. David oversaw the importation of Victorian koalas to the park, the establishment of kangaroo enclosures and the creation of the water fowl areas. Many of the picnic areas enjoyed by generations of visitors were established under his management. David left Tidbinbilla in 1970 to oversee the foundation of Namadji National Park.

In 1971 the nature reserve was officially gazetted.

The Tidbinbilla Nature Reserve is located adjacent to the Canberra Deep Space Communications Complex, part of the NASA Deep Space Network.

1988 saw one of the world's first international TV satellite linkups "World Safari" be broadcast from Tidbinbilla's kangaroo enclosure. The ABC linked up with fellow broadcasters across the globe in a live natural history program, which was an idea from David's daughter, Fiona Kerr.

In 2003, bush fires devastated the nature reserve with many of the koala population being lost to the fires. The Manager's Residence was also lost and there was damage to the Heritage listed Rock Valley and Nil Desperandum homesteads.

On 7 November 2008, the nature reserve was added to the Australian National Heritage List as one of eleven areas constituting the Australian Alps National Parks and Reserves.

Since 2011, Tidbinbilla has taken the charge of breeding of the critically endangered Northern Corroboree Frog, the Southern Brush-tailed Rock-wallaby and the Eastern Bettong on behalf of the ACT Government. It has been successful in the endeavour over the years.

Fauna
Tidbinbilla Nature Reserve has a wide variety of bushwalks - ranging from 30 minutes to over 6 hours. It is a native habitat for kangaroos, wallabies, platypus, koalas, lyrebirds, emus, and other wildlife. Ninety-nine percent of the park was burnt out in the Bendora bushfire of 18 January 2003, resulting in the loss of countless numbers of wildlife. Of the captive animals, only one koala, six rock wallabies, five potoroos, four freckled ducks, and nine black swans survived the bushfire.
