Jacqueline Maree Fanning, 38, from Victoria, tried to supply 17.85 grams of ice at the music festival.

The ice was found inside a white Mercedes van she and her boyfriend were driving into the festival, stated police facts tendered in court.

Police stopped the van before entering the festival and found the drug during a dog search.

The police also found 111.8gms of MDMA in blue tablets, 0.63gms of ketamine, 2.5gms of MDMA in a resealable bag bearing a Batman logo, cannabis and magic mushrooms.

Fanning's boyfriend claimed the other drugs and is in custody awaiting a court appearance on October 16.

Fanning was sentenced to 200 hours of community service and an 18-month community corrections order.

However, she hadn't completed any of the hours when she re-appeared in Goulburn Local Court on August 21 for breaching the order.

She told the court in April she would serve the community service in Wagga Wagga.

In court, Fanning's solicitor said his client was now living in a caravan park in Aubrey, Victoria where she wanted to complete the community service.

Magistrate Geraldine Beattie said Fanning "should have gone to jail ... You didn't even do an hour".

"When I sentenced you in April it was on grounds that you'd spend time in custody and on bail ... I brought it down to a community corrections order with community service work, but you had no intention of that."

Magistrate Beattie permitted Fanning to complete the community service in Aubrey.

"You have a commitment as an alternative to jail," she said.

Magistrate Beattie said Fanning would go to prison if she didn't report to community corrections in Aubrey by 3pm the next day.
