Victoria's legal system needs reform after a teenage girl who accused three brothers of rape was too "humiliated" and "devastated" to continue with the case, the mother of the alleged victim has said.

Amy*, now 16, alleged the three men raped her in a park in Geelong when she was 14 years old.

The three men were charged but the case was dropped last month after Amy was left distressed over the legal process.

The men had pleaded not guilty.

Amy's mother, Sandy*, said her daughter found the case too overwhelming.

"We are lucky enough to be well educated; we're quite tenacious, and it was still very, very difficult," she told ABC Radio Melbourne.

Sandy said her daughter had been traumatised after details that came out of bail hearings for the men were reported in the media.

"Things were said and there were no suppression orders, so the media reported on extraordinary detail, and that was harrowing," she said.

"She couldn't go to school. She was humiliated. We were devastated.

"I can't tell you how awful it is to watch your daughter, your beautiful daughter, who is a very vivacious, very sporty, very engaged young woman lying in bed not wanting to come out of her room, just holding her dog and sobbing because she was victimised through that process."

Sandy said she did not want to stop cases being reported, but more consideration was needed.

"I think cases need to be talked about in public otherwise nothing happens, but it's the level of detail," she said.

"I think there needs to be better training of magistrates, better guidance.

"We just know our experience was, our child was devastated by what was allowed to be reported and there was no protection in place for her."

Sandy also questioned the use of juries when sexual offences were heard in court.

"One of the things that we looked at is the complexity around the evidence and the complexity around the notions of reasonable doubt," she said.

"We all have some doubt and how clever barristers play with that notion of reasonable doubt so juries find that very, very difficult.

"I just think that being heard by a panel of judges … you'd get a better outcome in terms of just the law, and the facts being looked at rather than prejudices and unconscious bias, which we all have."

According to the Crime Statistics Agency, studies show only between 10 — 20 per cent of sexual assaults reported to police result in a conviction in court.

'If there are learnings we can glean … we will make those changes'

Premier Daniel Andrews said he and the state's Attorney-General Martin Pakula were willing to meet with the family and consider reforms.

"If there are things we can change, if there are learnings that we can glean from the tragedy of this case, then we will make those changes," he said.

"[There's] nothing we can do can ease her pain or change what occurred to her, but if we can — through the brave telling of her story and some reform — if we can make things just that little bit easier in the future, then that's government at its best, I think."

Mr Pakula said changes had already been made to the way young victims of sexual assault gave evidence, including giving pre-recorded evidence.

Carolyn Worth from the Centre Against Sexual Assault agreed the state's system could be improved.

"The idea of abolishing juries, I think, is quite dramatic; it would have a whole load of implications for the system," she said.

"But I think tightening up some of the procedures that have been brought in would make sense.

"Judges can close courts and make sure information does not go out … whether magistrates at bail hearings do that in sexual assault trials is another issue and maybe that needs looking at."

Ms Worth said time it takes for sexual assault cases to get to trial was also hard on victims.

Sandy said the system needed to better support those who reported crimes.

"There was a really overwhelming feeling of, I could go through this, have my life scrutinised back in the public domain, and for what. It was terrifying," she said.

"I think she [Amy] just was very torn between wanting to do this because she really does not want this to keep happening and feeling that it would in some way destroy her life more."
