Les entered the Camera Department in the UK as a Clapper Loader, and after 7 years progressed to Focus Pulling then eventually to Cameraman–a steady progression up the ranks which allowed him to acquire his skills as he went. Moving to Sydney in 1982, Les continued as a freelance Cameraman, setting up his own Production Company.

From 1999, he spent five years as a lecturer at AFTRS. Since then, Les has returned to the freelance market and continued lecturing in Cinematography.
