Major Leslie James (Les) Hiddins AM (born 13 August 1946 in Brisbane, Queensland), aka "The Bush Tucker Man" is a retired Australian Army Officer and war veteran, who is best known for his love and knowledge of the Australian bush. Hiddins is recognised by his distinctively modified Akubra hat and big grin.
Hiddins did two tours of duty in Vietnam between 1966 and 1968, the first as a forward scout in the infantry. In 1987 he was awarded a Defence Fellowship to research survival in northern Australia. He was the principal author of the Australian Army's Combat Survival manual (1987) and was awarded Member of the Order of Australia (AM) in 1987.
This research turned into the TV series The Bush Tucker Man. The series involves Hiddins driving around in a Land Rover Perentie, then in later episodes a Defender 110 with his trademark hat, finding and describing native Australian bush food or "Bush Tucker". Hiddins appeared in two ABC TV series of Bush Tucker Man, and the series Bush Tucker Man - Stories of Survival. He also appeared in the TV documentaries Pandora - in the Wake of the Bounty and The Batavia. His other publications are Bush Tucker Man - Stories of Exploration and Survival (1996), Bush Tucker Man - Tarnished Heroes (1997), Explore Wild Australia with the Bush Tucker Man (1999), Bush Tucker Fieldguide (2002). In 2000 Hiddins published four books specifically for children: The Coral Coast, The Top End, The Tropical Rainforest, and The Living Desert. He has released two CD-ROMs, From the Rainforest to Cape York Peninsula and From Arnhem Land to the Kimberley Ranges. The National Museum of Australia in Canberra has a Bush Tucker Man display with some of his original bush gear.
As a part of this research, Hiddins was introduced to the Kakadu plum (Terminalia ferdinandiana) by the Aborigines, who had used the plant for thousands of years. He sent the fruit to be analysed, and it was found to have the highest concentration of Vitamin C of any known natural substance in the world.
Hiddins retired from the Army in 1989 with the rank of Major but continued to serve with the Army Reserve until 2001, working with Indigenous Australian communities in northern Australia.
Hiddins and the Chain of Ponds Winery released the distinctive Bush Tucker Man wines in 2002.
Since 2001, Hiddins has been at the forefront of establishing wilderness retreats for war Veterans. "Pandanus Park", the flagship for these retreats, is a parcel of Normanby River frontage on "Kalpowar Station", adjoining Lakefield National Park in Cape York Peninsula.
On 28 March 2008 Hiddins was awarded an Honorary Doctorate of Science by James Cook University’s Faculty of Science, Engineering and Information Technology:
"in recognition for his outstanding and distinguished contribution to Australia and the northern Queensland community through his work on the ABC TV series Bush Tucker Man, his time in the defence force (including two tours of duty) where he worked with indigenous communities and establishing a bush retreat in Cape York for Vietnam veterans to enjoy." 
In 2009, Hiddins is enjoying his retirement, still bringing the Aussie bush to others through re-runs globally of the Bush Tucker Man series.
Ray Mears made a BBC programme about and with him, shown on BBC Two in June 2009 as part of his Ray Mears Goes Walkabout series.
