"This conduct is dishonest," the court document states.
Police Prosecutor Stuart Kute told magistrate Michael Barco earlier this year goods including Country Road clothing and "many sheets".  According to the document, Ms. Selkirk has requested a refund 31 times over a period of nearly three years, including a review in which she made 12 returns worth nearly $ 6300 over seven separate days in 2018
arrested in October and released on condition that she not enter any David Jones stores.
In proceedings which have already come to full circle, Ms Selkirk initially wants to contest the charges before being found guilty on the day her case is set for trial.
Mr Karim said that the prosecution must prove beyond a reasonable doubt that the "advantage" it received was $ 16,000.
The matter was adjourned to sentencing on 21 June, but days before Ms Selkirk had pleaded guilty and indicated that she was seeking new legal advice.
Last week, the Downing Hearing Center, Mrs Selkirk, had always claimed that she was not guilty, but was persuaded to plead otherwise in order to avoid the hearing.
Accepting her face, Mr Barko said that Ms Selkirk was an "intelligent and secular woman" who used her own legal knowledge to contribute to the proceedings.
"I felt that the defendant was not satisfied with the manner in which the proceedings were conducted, and was not satisfied with the plea of guilty," he said.
"When I read the facts, it struck me that there was something wrong."
He said that the "essence" of his concern was what was alleged in the statement of facts that Mrs. Selkirk received clothes from David Jones and then returned it for credit from her credit card: "Where is the benefit, where is the loss?"
But he said he found it "curious", she made a regular return of $ 16,000 worth of clothes .
The matter will be heard at a future date.
