Which rock star played the Australian bushranger Ned Kelly in a 1970 film?

One of the worst acting performances seen on camera.

Bonzodog, Ned Kelly wasn’t Irish his father was and a criminal transported to Australia from Ireland originally from Tipperary for stealing two pigs in 1841 and sentenced to 7 years

OzzysUndies, Ned Kelly was born in Australia, so wouldn't have had an Irish accent as is portrayed in the film
