Geologist, Biologist, Oceanographer, Conservationist and man of vision. Founder of Arkaroola - Mt. Painter Wildlife Sanctuary and Tourist Resort 28 years ago. Reg died in Scotland but his ashes were scattered over the crest of Mt. Painter, his favourite mountain, on the 29th December 1994.
In 1946 at Ediacara, he made the world's first discovery of the earliest living animal fossils (630 million years old). Most will remember Reg as a brilliant scientist, warm and fun loving.
Thirty years ahead of his time, he practised eco-tourism long before the word was invented. He was an inspiring leader of his profession and that of the petroleum industry. He lives on in the crystals of Mt. Gee, in the dimples of the Quandong seeds, in the shadowy niches amongst the woven branches of last year's eagles nest, in the open palm of a brittle native Callitris Pine cone and the crumbling charcoal fabric of an enduring yacca. An inspiration to all, he is a part of Arkaroola as Arkaroola is a part of him. His spirit is at peace. He is free where he belongs with a lone eagle as his guardian.
He gave generously. He expected nothing in return we shall miss him forever.
Griselda, Margaret, and Douglas Sprigg. January 1995.
