A teacher who is believed to have given birth to a 13-year-old student’s baby has admitted to sexually abusing the boy for more than a year.

Naomi Tekea Craig, 33, today pleaded guilty to 15 counts of indecently dealing with the youth, including sexual penetration of a child in late 2024, when he was 12 years old.

Police believe Craig, from Mandurah south of Perth, gave birth to the boy’s child following the alleged incidents between 2024 and 2025.

She appeared in the Mandurah Magistrates Court via audio-link and entered guilty pleas to all the charges before her case was “fast-tracked” to the District Court for sentence mention on March 27.

The magistrate extended Craig’s bail with strict conditions, including no contact with the boy and no unsupervised contact with any children other than her baby, born on January 8.

The court heard that Craig was excused from appearing in court in person today due to a medical condition, but magistrate Clare Cullen told her this could not be extended to her next appearance.

Naomi Tekea Craig was charged last month with persistent sexual conduct with a boy under 16 between 2024 and 2025, two counts of sexual penetration of a child by a person in authority, and possession of child exploitation material.

WA Police previously said Craig engaged in persistent sexual conduct with the student.

“At the time of the commencement of the alleged offending, the woman was a teacher at a school in the Mandurah District, and the male youth was a student,” a spokesman said.

Craig was initially charged with four offences in December before prosecutors laid an extra four charges last week.

An additional eight charges were laid before she appeared in court today, including five counts of sexual penetration of a child under 13.

The offending started in August 2024 and continued until Craig was charged in December.

Other charges include a person who persistently engaged in sexual conduct with a child under the age of 16 years and possessed child exploitation material.

Western Australian Police Commissioner Col Blanch has said a DNA test had been conducted after Craig gave birth and it was believed the victim was the father.
