The pair were later exonerated at a 1987 royal commission, but Chamberlain remained bitter.
After divorcing, remarrying, earning a PhD in education, becoming a teacher and writing several books, he still lamented the case as a "gross injustice".
"It was one of the worst perversions of justice and forensic science in Australian history," he said in 2014. "We had gone as babes in the woods. A Catholic lawyer described us as lambs to the slaughter.
"We had lived by the credo that if you have done nothing wrong, you have nothing to fear. It was dead wrong."
He believed the time Lindy spent behind bars had damaged her.
In 1990 the couple's marriage fell apart - Michael going on to marry Ingrid Bergner in 1994, with whom he had daughter Zahra in 1996.
Lindy Chamberlain also remarried, becoming Lindy Chamberlain-Creighton.
Despite the charges against the Chamberlains being cleared, a coronial inquest in 1995 delivered an open verdict. The fourth inquest into the case, in 2012, ruled that a dingo was responsible for Azaria's death.
The was what the first inquest, back in early 1981, had also concluded, and what the Chamberlains had steadfastly said since Lindy yelled those infamous words: "That dingo's got my baby."
The disappearance of Azaria prompted one of Australia's longest-running and most polarising legal sagas.
Despite the 2012 verdict, Chamberlain said he still had plenty of questions he wanted authorities to answer.
"I have peace and gratitude in my heart that Azaria's spirit now lies rested, and I have gratitude and peace in my heart because justice has been done for us," Chamberlain said in 2012, when releasing his book Heart of Stone: Justice for Azaria.
"But why did this happen to us? Why did it take so long? And why were there consistently a whole lot of mistakes made? It was systemic; it just wasn't one or two. It wasn't isolated and I have to ask the question, was it by accident?"
Chamberlain had three other children with Lindy - Reagan, Aidan and Kahlia as well as Zahra.
