Ex-NSW teacher jailed in Qld

A one-time NSW primary school teacher has been jailed for three months in Queensland after flying to Brisbane to meet a fictitious underage girl for sex.

The Brisbane District Court on Tuesday heard Peter Bosma, 51, believed he was corresponding with a 14-year-old after striking up an online chat via dating website Mingle2.com in April 2015.

He told the girl, who was actually a covert police officer, he thought she looked "cute" and continued communicating with her despite her regularly referring to her age and sexual inexperience.

Bosma was eventually arrested at a fast food outlet after flying to Brisbane to meet the girl in mid-May.

He pleaded guilty to a total of four counts, including grooming a person under 16 years for sexual activity, and shook in the dock as he was sentenced to a maximum term of two years imprisonment.

But Judge Michael Shanahan ordered he be released on a $3000 good behaviour bond after serving three months behind bars.

The judge set the bond for a period of five years as well as a probation supervision period of two years.

It came after prosecutor Aimee Sanderson told the court Bosma had talked about subjects like oral sex and orgasms to the fake teenager.

Reading from correspondence, she said Bosma told the girl: "What's age if there's a connection?"

Bosma also asked the girl to delete their conversations and later told police he'd reiterated to her they were just friends, Ms Sanderson said.

But defence barrister David James said his client had been subject to widespread media attention, quit his job and checked himself into a hospital after being charged.

Judge Shanahan conceded the offending had incurred "devastating consequences" but said it was "plain" Bosma had destroyed his own career.

However, he did accept a psychologist's report noting Bosma's judgment at the time was impaired by depressive illness and declared a period of 11 days as time already served.
