The Victorian government will look at domestic violence laws after a former AFL player agent avoided jail for assaulting his ex-fiancee.

Ricky Nixon, 49, pleaded guilty on Monday to assaulting Tegan Gould in his Melbourne apartment last year.

Magistrate Simon Garnett sentenced Nixon to a two-year community corrections order, saying he would have jailed him if not for his guilty plea and lack of prior convictions.

Premier Denis Napthine said the government would consider looking at domestic violence laws when he asked about the case on Tuesday.

"We'll certainly look at the penalties that apply," Dr Napthine told Fairfax Radio.

"We have toughened some of the penalties with respect to domestic violence and we want to make sure that people who perpetrate domestic violence are properly dealt with by the law."

Nixon released a statement via text message to Fairfax Radio stating his guilty plea was done mainly to protect his family and his ex-girlfriend's family.

"The main reason for my guilty plea yesterday is to protect my kids and ex-wife and Tegan's family from a protracted court case that would have affected everyone's lives for months," he said.

"I want to get on with my life and have worked tirelessly since this incident to do this."

He said his ex-wife had been "an absolute angel" to him, having funded his treatment at a psychiatric hospital last year, and she was adamant that he not speak to the media for the sake of their sons.
