Sarah Spiers disappeared the night of Australia Day. The state claims the wife was living with her parents at the time, and rejected an offer from Mr Edwards to go watch some fireworks.

The first wife couldn't remember when she went to her parents, whether it was in December 1995 or January 1996, and could not recall the fireworks invitation being linked to Australia Day.

Mr Yovich is now asking about the second Warnbro address the man moved to after leaving the couple's Huntingdale home.

This evidence has become confusing as the man's addresses for his two Warnbro houses are not the same as what the first wife said. The first wife said she had a baby at the second address, but the man is claiming that address was a place he moved into "much later".

"That was when [the first wife] vanished if you like ... when I came home from work and everything was gone," he said.

He's agreed he was living at a Warnbro address with a pool when his daughter was born.

The first wife recalled being at the Warnbro house with the pool when she rang Mr Edwards to tell him she was pregnant.

The pair didn't move into the house until September 1996, according to Alinta Gas records, despite the first wife claiming she told Mr Edwards about the baby early on in her pregnancy, around April or May 1996.

The timing is relevant as the state is claiming Mr Edwards found out about the pregnancy in the days before Jane Rimmer was murdered on June 9, 1996.

This witness has been excused.
