A judge has told a Queensland mother she grossly betrayed her daughter by taking sexually explicit photos of the child and sending them to her lover.

A childcare worker who sent graphic nude photos of her daughter to her lover has walked free from a Brisbane court.

The 41-year-old woman, who can’t be named for legal reasons, pleaded guilty in the Brisbane District Court on Tuesday to making and distributing child exploitation material over several months in 2010 and 2011.

The court heard the then-married women sent between 17 and 19 photos of her 12-year-old daughter to a man she was having an affair with.

Crown prosecutor Chris Cook said the most graphic of these involved close-up shots of the girl’s genitals, which her mother told her was for a doctor.

Her barrister John Fraser said it would be unfair to sentence his client to more jail time, given the offences occurred before she was sentenced last year to three-and-half years’ imprisonment for fraud.

The woman served 12 months actual time in custody for the offence, which involved stealing more than $63,000 from a child care centre she was working at between 2008 and 2010.

Judge Sarah Bradley agreed, saying she had made steps to rehabilitate since her release.

She also lost her blue card to work in childcare and no longer had contact with her children.

But Judge Bradley said it didn’t diminish the seriousness of the offence.

“You quite freely, over a period of time, grossly betrayed your daughter by exploiting her in this way,” she told the woman.

“It’s clear that this offending must have had a very significant impact upon your daughter.”

The woman was sentenced to two years’ probation for making the material and two years’ imprisonment, to be wholly suspended for three years, for distributing it.

The women did not say anything to waiting media as she walked from the court.
