A Perth woman wiped away tears on Friday as she pleaded guilty to being part of a child sex ring that involved the abuse of her young daughter by herself and two other men.
The 39-year-old mother, who cannot be named to protect the identity of the victim, admitted a total of 17 charges including sexual penetration of a child under 13, indecent dealing with a child and indecently recording a child.
She was charged after a member of the public discovered a recording device which contained videos of the woman and the two men abusing the then 8-year-old girl.
Police then set up a special taskforce, codenamed "Mirzam" to investigate allegations that the child had been abused during organised "swinging" sex parties.
The men, one of whom was the child's 45-year-old stepfather, pleaded guilty to a string of charges earlier this year.
The woman pleaded guilty when she appeared in the Perth Magistrates Court on Friday via video link from Bandyup Prison.
She spoke only to enter the guilty pleas and to say that she understood the charges against her.
Hundreds of charges remain
The trio are also facing hundreds of other child sex charges that were laid by police about a month after the initial charges, but they have not yet been required to plead to those counts.
On Friday the woman's lawyer, Simon Freitag, said it had been decided with WA's Director of Public Prosecutions that the three should be sentenced as soon as possible for offences they have admitted, and once that was finalised the other charges would be reviewed.
The woman was remanded in custody until she appears in the District Court next month, when a sentencing date may be set.
