SENIOR Constable Wendy Brooks remembers the first time she was called to a domestic violence case.

She was a fresh-faced 21-year-old, straight out of the academy.

What greeted her was just the start of a career of hundreds of domestic violence cases.

"The first domestic violence case I went to was horrific," Snr Const Brooks said.

"She (the victim) had a broken leg - he (the perpetrator) almost convinced me it wasn't his fault."

Fast forward more than a decade later and domestic violence cases are a daily instance for the Warwick police officer.

Snr Const Brooks said domestic violence was the most common job in her role.

"It's frustrating for us because often we're powerless in domestic violence cases," she said.

"Our job is to gather evidence and put it before the court - the rest is in the hands of the magistrate."

Speaking at a domestic violence Q&A in Warwick on Tuesday night, Snr Const Brooks shared some of her frustrations about the issue.

"I feel Queensland Police has failed police (officers) with knowledge in domestic violence situations," she said.

"We get taught about domestic violence for a month at the academy, but not once as police are we taught to say "where do we take her (the victim)?

"We take him (the perpetrator) but what support is there for her?"

Snr Const Brooks said more needed to be done.

The passionate police officer described domestic violence as a "violation of human rights".

"If you commit an act of domestic violence, you should be charged with a criminal offence," she said.

"Why in the domestic violence legislation do you get a second chance?

"Twice is not a mistake."
