Percy Trezise AM (28 January 1923 – 11 May 2005) was an Australian pilot, painter, explorer and writer as well as, notably, a "discoverer" (it is not certain that the local indigenous people knew about themselves as this was before the Mabo Decision overturned Terra Nullius), documenter and historian of Aboriginal rock art. He was born in Tallangatta, Victoria but is associated especially with Far North Queensland and the rock art galleries of the Cape York Peninsula. He died in Cairns, Queensland.

Trezise was born in Tallangatta (northern Victoria), of Cornish descent,^[1] and attended a bush school followed by Albury High School. His interest in Aboriginal people began when he won a copy of the Red Centre written by Findlayson during his years at high school. During World War II Trezise served in the Royal Australian Air Force, surviving the crash of a Wackett trainer in August 1942.^[2] From 1956 he worked in northern Australia as an airline pilot for Ansett and the Cairns Aerial Ambulance. From the air he learned to identify areas likely to contain Aboriginal rock art, which he subsequently explored on foot. During the 1960s he regularly overflew Dunk Island attempting to locate the Aboriginal galleries mentioned by E. J. Banfield in his Confessions of a Beachcomber (1908) and later walked in to find them based on his aerial observations.

He was a friend of writer Xavier Herbert, artists Ray Crooke and Ron Edwards and a collaborator with Aboriginal artist Dick Roughsey in a series of children’s picture books.

Honours

In 1996, he was made a member of the Order of Australia. In 2004, he received an Honorary Doctorate of Letters from James Cook University, in recognition of outstanding service to the community of far north Queensland. An episode of Australian Story, "Set In Stone" (2014), was dedicated to Percy Trezise. Introduced by Australian of the Year, Adam Goodes, it focuses on Trezise's 50 year relation with Quinkan rock art that continues with his sons.^[3]
