McCallum passed away on Wednesday (03Feb10) at a nursing home in Sydney. No other details about his death were released as WENN went to press.
The Brisbane-born TV guru began his career as an actor, training in London and going on to star in numerous roles on the stage both in the U.K. and in his native Australia.
He later moved on to roles in TV and film, before stepping behind the camera to write, direct and produce.
McCallum famously created 1960s TV hit Skippy the Bush Kangaroo, which became a global success, and worked on a string of movies including 1982 war picture Attack Force Z - which gave starring roles to then-unknown actors Mel Gibson and Sam Neill.
In 1971 McCallum was made a Commander of the Order of the British Empire (CBE) for his services to drama and theatre, and he was later named an Officer of the Order of Australia (AO) in 1992.
McCallum is survived by his wife Googie and children Joanna, Nicholas and Amanda.
