Shanice Freeman, 19, pleaded guilty to four charges, including aggravated burglary and three counts of theft, committed in October 2012.

The ACT Supreme Court heard Freeman acted as driver for two juveniles during a failed Bonython burglary on October 1.

Freeman drove the hatchback along a fire trial near the Mount Stranger Reserve and parked behind the home about midday.

A neighbour was alerted to the attempted burglary after hearing a house alarm and provided the car's registration and description of the occupants to the police.

Officer also found fingerprints and blood around a smashed window, which helped them identify the offenders.

Three days later, Freeman and a juvenile went to Westfield Woden about 1.40am.

Security camera footage captured the pair walking through the centre for more than an hour, searching kiosks, collecting goods, and trying to open the shutters and doors to stores.

The offenders then left with more than $7687 in property, including $2350 in beauty products.

About 7.15am, police found some of the stolen property in a Tuggeranong carpark.

They discovered a Southern Cross Club sign in sheet for Shanice Freeman among the items.

The court heard Freeman, who lived with her grandparents north of Newcastle, suffered from a brain injury after being involved in a car crash as a child.

As a result, she struggled with impulse and anger control, and depressive illnesses.

A medical report said, at the time of the offences, her brain injury meant she would have been unable to exercise appropriate judgment, was disinhibited, and unable to appreciate the wrongfulness of her actions.

She told one doctor that the Woden heist was "like when Bart and Millhouse [from the television cartoon series The Simpsons] broke into a shop after hours and had the time of their lives".

Freeman also admitted to "smoking weed all day every day" at the time of the offence.

Doctors said her disability meant full-time jail could have an adverse effect on her mental health.

Freeman was sentenced in December and the decision published this week.

Justice Hilary Penfold found the crimes were low to mid-range seriousness and accepted that Freeman was not the instigator or leader in the criminal activity.

The judge sentenced Freeman to 11 months jail, to be fully suspended upon entering a one year good behaviour order.

"I consider that no sentence other than imprisonment is appropriate, but I am also satisfied that there is no need for that sentence to be served in custody at this stage," Justice Penfold said.

"It's alright, you are not going to jail at the moment. I hope you won't ever be going to jail."

Justice Penfold said the order would likely be supervised by NSW Corrective Services.

The judged warned Freeman to stay out of trouble for the next year or risk time behind bars.

"If you commit another offence during that time, even a New South Wales offence, you might find yourself back before this court to be re-sentenced for those offences, and if that were a problem then you could be looking at some time in custody.

"But I really hope that you will be able to keep out of trouble for the next 12 months and then this will all be finished."
