Chris Dawson has spent another night behind bars as authorities work to process his conditional release from a Sydney prison.
The 70-year-old, who is accused of murdering his wife Lynette in Sydney in 1982, was extradited from Queensland and charged with murder earlier this month.
The former rugby league player and teacher intends to plead not guilty to killing his wife who was 33 when she disappeared from Sydney's northern beaches in 1982.
Dawson's family, including his twin brother, came up with $1.5 million in real estate and other assets to post his bail on Monday.
But court and prison authorities had yet to process the complex release application late on Tuesday and he remained behind bars overnight.
He is expected to be released on Wednesday but must live with his wife on the Sunshine Coast in Queensland, report daily to a local police station and surrender his passport.
