Kira Lee Meagher, 23, appeared via video link in the ACT Magistrates Court on Tuesday charged with aggravated robbery, stealing a car, using an unregistered and uninsured vehicle, fail to exchange details following a collision, fail to keep left and fail to comply with a health direction.

The court heard that Ms Meagher, who has not pleaded to the charges, allegedly robbed another driver on the side of a road after causing a collision on Monday.

Magistrate James Stewart said police documents tendered to the court allege Ms Meagher of being "well intoxicated and behaving in a very, very erratic, unlawful and dangerous manner in terms of her driving and the allegations".

Ms Meagher was already on bail for other charges, including two theft charges to which she pleaded guilty.

The court heard she stole $6000 worth of car engine parts and a $529 guitar in other incidents.

The seriousness of some of the charges meant Ms Meagher had to show exceptional or special circumstances before her bail could be granted.

Defence lawyer Georgina Meikle argued that those circumstances included the alleged robbery being overcharged because the aggravating portion was Ms Meagher's pet German shepherd being considered an offensive weapon at the incident.

"There's nothing in those facts that would suggest it was being used as a weapon. It was simply in Ms Meagher's company at the time," Ms Meikle said.

Ms Meikle also said charging Ms Meagher with a major theft offence for her stealing the guitar was also an overcharge.

Other factors that the lawyer, of Legal Aid, cited included the defendant's young age, limited criminal history and her life "unravelling in the past 6-12 months" due to being homeless and use of prohibited drugs.

"She has been quite frank in indicating that she's someone who's had her life spiralled over the last year ... which coincides with many of these allegations," Ms Meikle said.

"She was recently suffering from drug induced psychosis, which only just recently ended."

The court heard Ms Meagher was studying a double degree in nursing and paramedicine.

The prosecutor opposed bail, arguing that the presence of the pet dog was considered an offensive weapon even if it were not used.

"The complainant did fear as a result of the presence of the German Shepherd," the prosecutor said.

She said a limited criminal history and drug use were common features among many of the court cases.

Ms Meagher also spoke to the court, saying she had been living with her dog in her car due to being homeless.

Magistrates James Stewart denied bail, saying that Ms Meagher's circumstances were compelling but not exceptional and that the charges were not overcharged.

"Sadly, even when I combine those [factors] to their greatest strength, there's nothing really special or exceptional about them," he said.

Mr Stewart said her spiralling drug abuse, first time in custody and lack of criminal history were not special and that they were commonplace in other court matters.

Ms Meagher is scheduled to front court again on October 12.
