Learnie Joy Riley was sentenced to an 18-month term of imprisonment with a non-parole period of 12 months for larceny, the latest offence in an extensive criminal history.

It was committed while she was subject to bonds imposed for previous property-related convictions, which were revoked in Dubbo Local Court on Wednesday.

Magistrate Greg Grogin said it gave the court "no joy to jail a pregnant woman" but Riley, 35, had shown "a constant and consistent disregard" for the law.

Riley was supported in court by her mother, brother and case worker from the Connections Program and understood the situation she was facing, her defence said.

The representative from the Aboriginal Legal Service said Riley was in "the unenviable position of being due to give birth in April".

She had already spent 51 days in custody before she was bailed and the defence asked the magistrate to take the time into consideration.

She had underlying issues of drug and alcohol addiction and the offence was committed at a time when she felt she had nothing in life, the court heard.

The defence submitted Riley was someone who would benefit from a significant period of parole and that when released she would also able to access the Connections Program, which was available to women who were pregnant or who had given birth in prison.

Mr Grogin said the offence of stealing handbags to the value of $630 from Myer on September 13 was premeditated, and that Riley had someone waiting for her outside in a car.

She had run from the store with the property, and was heard to say "quick drive" to avoid apprehension, the court heard.

The offence was committed for "greed rather than need", the magistrate said.

By pleading guilty the 35-year-old breached a number of bonds, imposed for offences including stealing driving lights, a jacket, hair trimmers, a vacuum cleaner, and clothes from various stores, the court heard.

Riley had received numerous opportunities from the court to amend her ways, but despite that she showed a "constant and consistent disregard for the law" and to the community, particularly business operators, Mr Grogin said.

While the defence had submitted there were strong prospects for rehabilitation, the magistrate said he found that difficult to accept.

He said Riley's plea of guilty was a mitigating factor but the aggravating factors were her record and her continuing behaviour.

"It gives the court no joy to jail a pregnant woman. . . a woman or . . . anyone," Mr Grogin.

The magistrate dealt with the matter by way of concurrent sentences to start from December 1, taking into account time previously spent in custody. Riley will be eligible for release on November 30. She blew a kiss to family members as she was led from the court.
