A mother-of-two who is one of Australia's worst female paedophiles will be released from jail without being properly rehabilitated.

The 55-year-old woman, who cannot be named for legal reasons, was jailed in 2007 for molesting six children with her former de facto partner.

She found victims by advertising as a babysitter. Some were as young as three.

Other victims included her husband's niece and nephew, shortly after their father had died.

The pair, who photographed the abuse, were only caught when the images were found on their computer.

The woman is due to be released on parole this month, despite families of the victims urging for her to remain behind bars while she does a sex offenders rehabilitation course.

State Parole Authority granted parole after her non-parole period expired in October last year, The Daily Telegraph reported.

She hasn't completed a sex offenders course as the courses are only provided to men.

Parole chairman Justice Graham said releasing the woman on parole meant she would be able to complete therapeutic courses to address her aggression and former ice addiction.

She has been unable to do the courses in jail as she was in protective custody, he said.

Corrections minister Anthony Roberts told the Daily Telegraph he will looking into the matter and plans to seek advice on the case.
