An Irish woman who killed her fiance in Sydney told a judge he would punch strangers, bite her body all over and accuse her of sleeping with other men.

Cathrina Cahill said she could not look at other men while with David Walsh, nor could she look in the mirror when driving as there might be a male driver behind.

If she did, Mr Walsh would say: "I hope you got a good look, slut."

Cahill (27) was giving evidence at New South Wales Supreme Court at her sentencing hearing for the manslaughter of Mr Walsh (29), who was stabbed in the neck at their home last year.

The couple shared the property in Padstow, Sydney, with two other Irish people.

Cahill, from Wexford, was originally charged with murder, but the crown accepted her plea of manslaughter due to the abnormality of her mind at the time. Asked about the death, she said: "There is not a day goes by when I don't think about David's family. I loved him so much.


"He told me no matter what I did I would never get away from him and if I ever got with anybody else he would make my life hell."

She said he blocked people from her Facebook account, deleted texts and phone numbers and was convinced she was having an affair with her boss.

He would come to her work and make a gesture, which she demonstrated, of running a finger across his throat, she said.

Cahill told of a string of incidents when Mr Walsh punched men, including his friend, Paul Mulligan, who arrived to stay.

"I was in my bedroom and David started accusing me of being with Paul Mulligan, which was totally untrue," she said.

"David came out and just hit Paul." Mr Mulligan left.

The court heard Cahill was with a female friend at a hotel when a man started talking to the other woman

"David came in and hit the guy so hard he landed on the floor," she said. "He said, 'He won't look at my missus again'."

She said Mr Walsh punched holes in the house walls, threw a bottle through a TV and "would constantly break things".

He would grab her face "and constantly bite me - that was his thing", she said.

The hearing will continue next Friday.
