Ewart appeared in hundreds of Australian radio, theatre, film and television productions. To many thousands of Australians who grew up in the 1950s and '60s he will be remembered as 'Jimmy', boyishly cheeky co-presenter of the ABC Radio Children's Session, and in the title role of its long-running serial The Muddle-Headed Wombat.
He was well known for his role in the film Sunday Too Far Away, his ongoing role in the Australian TV series The Restless Years in 1980–81, and his lead role opposite Nicole Kidman in Bush Christmas.
