When veteran curator Nathan Pharaoh found a box of old slide films while working at the Braidwood Museum, he knew he had stumbled upon something special.
The box was filled with a "well-categorised" and "nationally significant" collection of photographs that had likely never seen the light of day.
Containing 1100 slides, which were donated to the museum by Braidwood resident David Jones in 2023, the collection included images of the Central Desert, the tree burial traditions of the Warlpiri people in the Northern Territory, the Queen's 1963 visit to Alice Springs, and glimpses of Canberra and Adelaide more than 60 years ago.
The photographer is known to be Mr Jones's uncle, John 'Johno' Jackson. Beyond the name, he remains a mystery.
With the collection was fast deteriorating, Mr Pharaoh and the Braidwood and District Historical Society turned to crowdfunding for help to digitise the 35mm Kodak slides.
"There was an algae bloom developing and the plastic slides were deteriorating quite rapidly," Mr Pharaoh said.
Following an overwhelming response, the 63-year-old slides, many on the verge of total destruction, were sent to Melbourne for high-resolution digital restoration.
The stunning results arrived two weeks ago.
"It is a complete journey of someone spending considerable time in the Central Desert in 1963," Mr Pharaoh said.
Among the standouts are shots of the Bangtail Muster and the Alice Springs Show from the mid-1960s, featuring First Nations elders and Afghan cameleers.
Jackson's camera also chronicled daily life in the Northern Territory, capturing scenes of work, leisure, and transport alongside rock art and sacred places of worship.
Most notably, the mysterious Braidwood photographer captured rare images of the Warlpiri people in the Central Desert, including Kantirirri, the traditional and sacred practice of tree burial.
"The images are quite special," Mr Pharaoh said, a curator on leave from the National Museum of Australia, deeming the revived photographs "secret and sacred".
Because some of these Northern Territory photographs hold immense cultural and historical significance, they cannot be made public. The curator has since contacted Warlpiri elders regarding the findings.
The photographer had written notes and beautifully categorised the slides into a wooden box found.
Despite these developments, photographer John 'Johno' Jackson remains an enigma.
"He was a resident of Braidwood and nothing more is known about him. He may have worked for the mining department," Mr Pharaoh said, pointing to various photographs of mining operations and the inauguration of the Ord River Dam Project in Kimberley by then-Prime Minister Robert Menzies in July 1963 taken by him.
While the Braidwood Museum team's research into Jackson's identity has hit a brick wall, his remarkable camerawork speaks volumes.
His legacy is set to deepen, with the recent discovery of a second box containing another 1000 photographic slides from the same Braidwood photographer.
