A former colleague of Lynette Dawson has claimed the mother was feeling very positive about her future just a day before she vanished.
Susan Strath said today she felt great about giving evidence in the murder trial of Chris Dawson after waiting more than 40 years to speak about Lynette's disappearance.
"I am here to see justice done… so let's hope that happens," Strath said outside court.

The pair worked together at a childcare centre inside the Warriewood shops on Sydney's Northern Beaches on what would be Lynette's last shift before she disappeared in January 1982.
Strath said Lynette confided in her about issues at home, including the troubled teenage babysitter moving in and being caught naked in the backyard pool.
She also claimed Lynette told her about Dawson leaving the family over Christmas in 1981 before reappearing a few days later.
Strath told the court she believed things had turned around after seeing the couple walk hand-in-hand following marriage counselling.
"I asked how did it go? And Lyn said, 'Oh it was really good, really positive and I am hoping we can move forward and work together'," Strath told the court.
The day after this conversation, Dawson alleges Lynette ran away.

Three years after Lynette vanished, Strath said she lodged a formal complaint with the NSW Ombudsman as she was concerned police had failed to investigate what she thought to be suspicious circumstances.
"I was never interviewed, no one ever came looking for her," Strath said outside court.
"I just said what's happened, what have the police done to look for my friend?"

Anna Grantham considered herself Lynette's best friend and also gave evidence during the trial today.
Grantham told the court of a time when Lynette agreed she could have been killed when Dawson allegedly grabbed her by the hair and pressed her face into the mud.
Dawson has pleaded not guilty to murdering his wife.
The trial continues.
