Gravely ill Aussie underworld figure says he'll reveal secrets to police

A seriously ill former underworld figure says he'll make a deal with authorities to reveal where 10 bodies are buried. 

Charlie Quinlan, 55, is gravely ill in hospital, but says he wants legal protection before he talks to authorities about things he knows from his days as an underworld figure in Australia. 

His lawyers have said they will accept a deal with police if Mr Quinlan reveals information. 

Mr Quinlan last month told 7 News from a hospital bed that he knows where 10 bodies, including two retired police officers, are buried - a secret he says has been "eating away" at him for 15 years.

He claims Outlaws bikie boss Sidney Collins is buried at Tabulam in northern New South Wales, while the other nine bodies are believed to be in the Crookwell area in the state's south. 

Mr Quinlan would not say if he was involved in the killings unless he was promised immunity first.

NSW Police said the details of the deal were still being finalised.
