Chris Dawson, 70, was arrested on a warrant and hauled before a Queensland court on Wednesday nearly four decades after his wife was last seen alive.
The 70-year-old was arrested on the Gold Coast on Wednesday morning and taken to Southport Police Station.
A podcast about the disappearance of a young mother in Sydney 36 years ago has led to the arrest of her husband after new witnesses came forward with fresh evidence about the case.
Dawson is a former first grade rugby league player turned high school teacher.
Comm. Fuller said two additional witness statements had been taken since April, but would not comment on the significance of that evidence.
Fuller said in a press conference that New South Wales' unsolved homicide squad began re-investigating Lynette Dawson's disappearance since 2015, but new interviews from the podcast "helped [them] tie pieces of the puzzles together".
Fuller said authorities have not located Dawson's body, and that finding her remains is "not crucial to finalising the matter", but maintained "we certainly won't give up on that search".
Police have spoken to Lyn Dawson's family this morning, who are "relieved".
He's been refused bail and will appear at Central Local Court today.
"A team of dedicated detectives has been investigating this case over the past three years", Det Supt Cook said.
The family of Chris Dawson has released a statement, defending him.
Former student Robyn Wheeler was vice-captain of the school and has given detectives information about the alleged abuse
He'll be charged with murder later today.
But his arrest yesterday on the Gold Coast was a sudden development of case that has never been far from the headlines during the 37 years that have passed since Lyn's disappearance.
Police are reportedly looking into chartering their own flight to get Mr Dawson back to NSW.
He has said that she abandoned the family for a religious group, the BBC reported.
"It's my understanding that there were two additional statements that were a by-product of the media and the work that the media has done".
"We have sold homicide before without identifying the body", he continued.
Police, who have conducted several digs at the Dawson's Bayview home in Sydney to find Lynette's body, said they have amassed "an enormous amount of evidence".
Sydney couple Chris Dawson and Lyn Dawson (nee Simms) married in 1970 when they were both 21 years old.
"We have to also ensure Chris gets due process".
However, prosecutors have previously said there was insufficient evidence to lay charges.
"For it to finally happen it nearly doesn't seem real yet to me".
