Courage was the main armour that Lindy Chamberlain-Creighton had relied on for the past three decades that her family lived in fear and anxiety following the mysterious disappearance of her infant daughter Azaria back in 1980.

Millions of Australians were convinced that Mrs Chamberlain-Creighton had a hand in the unfortunate demise of her own daughter and her subsequent conviction in 1982 elicited applause and approval from a nation that was collectively aghast by such a grisly crime.

And more insults rained on her family as Mrs Chamberlain-Creighton won exoneration from the Royal Commission five years later, which effectively ended her lifetime prison-term but failed to take away the miseries she carried until this Tuesday this week.

Yesterday, Elizabeth Morris, Deputy Coroner for the Northern Territory, officially ruled that the Chamberlain had nothing to do with Azaria's death.

Ms Morris said that strong forensic evidences laid out for probers what really happened while the Chamberlains were camping out at Uluru: "A dingo or dingoes entered the tent, attacked Azaria and dragged or carried her from the area."

Her findings Ms Morris stressed, corroborated the assertions of the Royal Commission when it decided in favour of Mrs Chamberlain-Creighton basing on careful assessment of circumstances and evidences surrounding the case.

"In considering all the evidence I am satisfied the evidence is sufficiently cogent and excludes all other reasonable possibilities defined (as to) what occurred," the NT Deputy Coroner was reported by The Age as saying on Tuesday.

At the same time, Ms Morris offered her "sincere sympathy over the death of your dear and loved daughter Azaria," stressing that her apologies may not be enough to alleviate the sufferings of the Chamberlains.

All those seemed to have disappeared as Mrs Chamberlain-Creighton told reporters immediately after the decision was handed down that she was "relieved and delighted to come to the end of this saga."

The NT coroner's affirmation of her earlier exoneration only proved that "you can get justice even when you think all is lost."

Part of that justice is the turnaround summoned by some personalities to express their regret for joining the bandwagon of hatred for the Chamberlains while the case was still raging.

One of them was broadcaster Wendy Harmer, who admitted yesterday in her blog that she's one of the millions in Australia that had prejudged that Chamberlains.

"I am truly sorry for your loss ... and thank you for your forbearance and patience in the face of my blind ignorance and cruelty," Ms Harmer wrote on her blog.

In an interview with ABC today, Mrs Chamberlain-Creighton lauded the courage displayed by Ms Harmer and all the others who admitted that they've brought unnecessary sufferings to her family.

"Good on her, she's only the second one ever to do so in the media," Mrs Chamberlain-Creighton told ABC in acknowledging that Ms Harmer indeed apologised to her family and was of the few media people to do so.

"I think they have a huge amount of courage to admit that they were wrong," she stressed.
