Husband of Australian woman missing since 1982 to spend week behind bars following murder charge

The husband of Sydney mother-of-two Lynette Dawson, who's been charged with her murder almost 40 years ago, will spend at least a week behind bars before applying for bail.

Chris Dawson, 70, faced Sydney Central Local Court via video link today charged with the murder of his wife on Sydney's northern beaches in early 1982. The court heard Dawson intends to plead not guilty.

His barrister, Greg Walsh, told the court the matter was "quite big" and asked that a bail application be set down for December 14.

Dawson, a former professional rugby league player and teacher, arrived in Sydney this morning after being extradited from the Gold Coast.

Fresh statements from at least two witnesses led to his arrest in Queensland yesterday morning.

The new evidence helped police "tie pieces of the puzzle together", NSW Police Commissioner Mick Fuller said yesterday.

Some of the additional material surfaced as a result of The Australian newspaper's investigative podcast The Teacher's Pet.

Ms Dawson was 33 when she went missing in 1982 leaving behind two young daughters.
