Born in Perth, Western Australia, Harris was a champion swimmer before studying art. He moved to England in 1952, where he started to appear on television programmes on which he drew the characters. He also began a musical career initially with the piano accordion. He wrote the famous song "Tie Me Kangaroo Down, Sport", and when performing in Canada he introduced his popular routine Jake the Peg. He often uses unusual instruments in his performances: he plays the didgeridoo, has been credited with the invention of the wobble board, a rhythmic percussion instrument, and was associated with the Stylophone, a small electronic keyboard instrument.
From the 1960s he has become a popular television personality, presenting shows including Rolf's Cartoon Club, Animal Hospital and various programmes about serious art. In late 2005 he painted an official portrait of Queen Elizabeth II, which was the subject of a special episode of Rolf on Art.
