Michael Chamberlain, who fought a long and bitter battle for justice after his baby daughter was snatched by a dingo at Uluru in 1980, has died.

The 72-year-old died in Gosford Hospital on Monday evening as the result of complications from acute leukaemia, a long-term friend told Fairfax Media.

Stuart Tipple, who was his friend and solicitor for decades, said on Monday that Dr Chamberlain had gone into a coma on Sunday night.
