Rosie Batty told of killer dads: inquest

A doctor says she reminded Rosie Batty of the Farquharson boys and Darcey Freeman, children who were killed by their fathers, in the months before her ex-partner murdered her son.

Doctor Lisa Farlow said she raised the high profile cases, in which Robert Farquharson and Arthur Freeman killed without warning, during a consultation in July 2013.

But she said Ms Batty had been adamant her ex Greg Anderson would not harm their son, Luke Batty.

"It was just making her aware that the situation sometimes occurs and to be mindful of it," she told Victorian Coroner's Court on Tuesday.

"She was adamant Greg Anderson did not represent a threat to Luke, that he loved him."

Anderson killed 11-year-old Luke Batty with a cricket bat and knife on February 12 as they played together in the nets at the Tyabb oval after cricket training.

Anderson, 54, had multiple arrest warrants out for him at the time he killed his son and police shot him dead at the scene.

Dr Farlow said she was playing devil's advocate when she raised the cases to Ms Batty, not issuing a warning.

The inquest into Luke's death also heard from therapist Kate Perry, who said Luke had been suffering from the "chaos in his private life" in the lead up to his death.

She said she believed Luke felt his relationship with his father was a burden of sorts, but didn't fear him.

"He was living with a really hard reality," Ms Perry said.

Luke felt the burden of having to call his father and organise times to catch up with him, Ms Perry said.

She said Luke once said of his relationship with his father, "I think I'm the only thing he's living for."

The inquest continues.
