10.05am: Mr Davis asked witness Kerry-Anne Walker whether her friend Allison Baden-Clay suffered from depression.
"She suffered from depression, yes," Ms Walker said.
"After her children were born, she told me she suffered from post natal depression."
However, Ms Walker said Allison had been well the past couple of years.
"She was in a very good state of mind before she went missing," she said.
"There were a few occasions where she mentioned she would take her anti-depression medication.
"Maybe twice in a 10 year period.
"She became more withdrawn. She didn't initiate any catch ups as she had prior."
Mr Davis said Ms Walker, in her statements to police, had suggested that the bouts of depression were due to her troubled relationship with her husband.
"I felt that at the time," she said.
"But you're not a psychologist," Mr Davis said.
