Career
Duncan has been climbing since 1988, guiding since 1994 and has climbed and guided on all seven continents. He started out on the crags and in the gorges of National Parks of Australia, then moved on to larger mountains around the world. He is one of few Australian mountaineers to have climbed and guided Mountain Everest and the equal first South Australian to summit.
He has also guided Cho Oyu successfully twice.
In New Zealand he has climbed technically hard (grade six) routes and is one summit away from completing all the 3000m peaks in New Zealand. He has also climbed the fabled Seven Summits and is one of only about a dozen guides to have led expeditions to all of the Seven Summits.
In 2006 Duncan worked with a group of young people with cancer known as CanTeen, guiding them to climb Mountain Kilimanjaro. He founded DCXP Mountain Journeys Pty Limited which he ran for over a decade guiding the seven summits including guiding Mountain Everest commercially and summiting Mountain Everest three times.
Other destinations included the Kokoda Track in Papua New Guinea which his company DCXP guided thousands of Australian Trekkers over between 2003 and 2010.
In 2010 Duncan sold DCXP to Katie Sarah, also a seven summiter, and shifted back into the field of geology and became the Managing Director of the public company Endeavour Discoveries Limited. Endeavour is a mineral exploration company based in South Australia exploring for base and precious metals such as Nickel and Gold in South Australia and the Northern Territory. In 2011 he became the Chairman of Endeavour Discoveries Limited.

The HDFA has raised over A$$100,000 in its first year and built a boarding school in Nepal with some of the proceeds in the remote Kanchenjunga region of East Nepal.
