Withers, born Georgette Lizette Withers in India in 1917, was best known for being in Alfred Hitchcock's "The Lady Vanishes" and TV's "Within These Walls," the BBC reported. She also was the first non-Australian to be named an Officer of the Order of Australia (1980) and was appointed a Commander of the Order of the British Empire in 2002.
The British actress, who died Friday, began acting at 12 and starred in more than 40 films. Her last role was in the 1996 Australian film "Shine," the Sydney Morning Herald said.
Withers was raised in Britain and moved to Australia in 1958 with her husband John McCallum, who died last year.
"I think it's the end of a golden era with the two of them passing now, and in particular Googie," said John Frost, "Wicked" producer.
