Charles Bryan Tupetaiki Campbell has pleaded guilty to producing, disseminating or possessing child abuse material.

The 56-year-old was arrested in February on internet-related charges.

He was the director of the Kip McGrath education centre in Dubbo and a former school principal and Charles Sturt University lecturer.

An adjournment was granted when Campbell made a brief appearance before Magistrate Andrew Eckhold yesterday.

A defence solicitor told the court Campbell had taken part in a medical review on June 30.

"The report from the doctor is not ready," the solicitor said.

Magistrate Eckhold ordered Campbell to return to court for sentence on Tuesday.

Prosecution facts tendered to the court said Campbell managed a learning centre attended by students ranging in age from 5 to 21.

A 15-year-old boy who came to the centre for tutoring completed work on a desktop computer with the assistance of Campbell.

Police said the youth was working on a computer screen and keyboard when he accidentally hit a key causing the Kip McGrath program to minimise. An internet link opened on the computer screen.

Police said the youth used a mouse to click on the link displayed. A video of a young Asian boy appeared.

The youth closed the link and did not disclose what he had observed.

Police were later informed and an investigation was initiated.

At 9.30am on February 13 Campbell voluntarily attended Dubbo police station.

During an interview he admitted watching pornography on student computers in the Kip McGrath centre before and after tutoring sessions.

Prosecution facts revealed Campbell downloaded images and movies from the internet onto storage devices. He would later upload images and videos onto student computers and watch the material.

Prosecution facts said Campbell gave police permission to seize and examine computers and storage devices at the Kip McGrath centre and his home address.

Officers removed computers and USB devices from the work place and a laptop computer, DVDs and CDs at a West Dubbo house.

Detectives conducted a review of seized material and used the Oliver Scale 1 to 5 rankings to assess the seriousness of the child pornography.

At 5.30pm on February 14 police went to Campbell's home where he was arrested and informed of his right to silence.

Prosecution facts said Campbell participated in an electronically recorded interview and made full and frank admissions about downloading and possessing child abuse material.

Campbell said he had attempted to restrict child pornography to a computer located at the Kip McGrath reception desk and had foolishly also used student computers to download and view material.

Campbell told detectives he felt a compulsion and had been downloading child abuse material from the internet since the late 1990s.

According to bail restrictions, Campbell must live at a specified Dubbo address and report to police. He has been banned from using any internet enabled device and prohibited from approaching any point of international departure.

He cannot be in the presence of children under the age of 16 unaccompanied by their parents and was required to hand two passports to the officer in charge of Dubbo police.
