The woman, who appeared before the ACT Children's Court briefly this morning, cannot be identified because she was 17 when the offence took place.

Magistrate Karen Fryar told the woman it was charged that ''in the ACT on September 1 2008, you did murder Cameron Anderson''. The woman did not enter a plea and did not apply for bail.

Her lawyer, Bernard Collaery, said she would make a bail application next week. Ms Fryar remanded her in custody until the hearing on Wednesday.

The woman made a brief appearance in Queanbeyan Local Court yesterday where she was extradited to the ACT to face the charge over the stabbing death of Mr Anderson, 19.

Mr Anderson's body was found on the steps of Kingston's ABC Learning Centre, metres from the spot where police believe he was stabbed by the woman, who was 17 years old at the time.

The Queanbeyan man had suffered several stab wounds to the chest and was still wearing the chef's pants he had worn during his shift at a Green Square cafe the previous day.

Police are expected to allege that the two had been drinking at a Green Square pub on the night of Mr Anderson's death.

Several hours after the alleged incident, the woman presented herself to police and gave a version of events surrounding the young chef's death.

The woman, who did not oppose the application to extradite her, was arrested in Cooma yesterday morning, and released by NSW authorities into the custody of ACT Policing Detective Senior Constable Hilda Gough.

Under the ACT's child protection laws, the alleged killer's name, image and suburb cannot be published.

Her lawyer, Bernard Collaery, told NSW magistrate Brian Van Zuylen yesterday that the woman was extremely ''fragile'' and should be treated as a prisoner at risk while she was in custody.
