Rex Dupain was introduced to photography at an early age. When he was four he won a Kodak instamatic camera and in 1969, at 15, he won first and second prizes in the Sydney Royal Easter Show photographic awards. He went on to study painting and drawing at the National Art School and received a Master of Fine Art from the University of New South Wales. His paintings have been exhibited at galleries around Australia and are included in private collections internationally.

In 1995 Rex returned to working in black and white photography. His photographs have appeared in exhibitions, fine art catalogues, private and corporate collections, magazines, newspapers and postcards.

Rex's work features Australian photographs encompassing his experiences both in his local hometown Sydney and as far as the outer reaches of Arnhemland. Rex has continued the iconic tradition begun by his father, Max Dupain, and his images such as 'Sunbaker' 1937. Rex, like his father, looks to Sydney life and beach culture for inspiration but with a fresh eye, forever searching for what embodies today's surf and beach addiction in Australia. Several images were included in 'Federation', a National Gallery of Australia exhibition currently touring the country.

'Rex Dupain sees the concrete platforms of the Bondi promenade as a showcase for modern flâneurs and voyeurs, their manners and social identity. The watchers on the promenade are as interesting as the surfers or sunbakers, and his photograph captures the excitement and energy of the interaction between watching and being seen' Federation: Australian Art and Society, National Gallery of Australia, 1901-2001p.164.
