Nock began studying piano at 11. He attended Nelson College for one term in 1955. By the age of 18, he was performing in Australia. He headed a trio that toured England in 1961 and then attended Berklee College of Music. He was a member of Yusef Lateef's group from 1963 to 1965.
During 1968–1970 Nock was involved with fusion, leading the Fourth Way band. After a few years he became a studio musician in New York (1975–1985) and then returned to Australia.
He currently lives in New South Wales where he teaches at the Sydney Conservatorium of Music and performs with both his trio and big band. Nock recorded Duologue, a live date, with saxophonist Dave Liebman in 2004.
