Ex-AFL player Nick Stevens told his former girlfriend he was going to kill her and her dad, after smashing her face into a tiled kitchen wall.

He also caused grazing to her face on a separate occasion by pushing her head into the outside wall of a house, and pushed and kicked her when she threw wine at him during a fight.

The 37-year-old former Carlton and Port Adelaide player was on Thursday found guilty of 12 charges following attacks on a woman he was dating in 2012 and 2013.

A Ringwood Magistrate found Stevens guilty of five counts of assault, three counts of threatening to kill, one count of threatening to inflict serious injury and two counts of intentionally causing injury.

Stevens was also found guilty of one count of property damage after smashing the woman’s phone, but allegations he broke a window were dismissed.

Magistrate Nunzio La Rosa said he had to dismiss charges arising from some of the alleged incidents because of insufficient evidence, but he otherwise found testimony by the woman to be consistent and convincing.

“I was impressed with the complainant and the manner in which she gave her evidence,” Magistrate La Rosa said.

“I accept the complainant as truthful.”

Stevens had pleaded not guilty to a total of 31 charges.

During his trial, he said the woman made up the allegations of abuse to ensure he’d repay money he owned the woman, and that she also faked her injuries.

Magistrate La Rosa said some allegations, including a charge that Stevens threw a chair at the woman, could not be proven but he rejected the proposition her injuries were self-inflicted.

Stevens will return to court for a plea hearing on March 11, and will be sentenced at a later date.

He declined to comment outside of court.
