That led County Court judge Marilyn Harbison to say she didn’t “have any confidence” that 20-year-old Regulski would not offend again.

“One of the things I have to be mindful of is the protection of the community,” she said yesterday.

“It’s an appalling thing to do with a young boy, to have him send pictures of his erect penis.”

Regulski carried out his crimes from his Wodonga home against two boys — a 14-year-old in Queensland and a soon-to-turn 11-year-old in Western Australia.

A constantly sobbing Regulski pleaded guilty in Wodonga yesterday to two Commonwealth counts of causing child pornography material to be sent to him over a carriage service and one Victorian count of possessing child pornography.

The first Commonwealth charge related to incidents between August 14 and September 17, 2011, and the second between about July 7 and August 26 last year.

The Queensland boy was lured into a trap Regulski set after setting up a false Facebook profile in early 2011.

The unemployed Regulski pretended to be a 14-year-old, year 9 schoolgirl originally from Queensland who attended a North East school.

The victim was one of about 100 young people aged 13 to 17 who Regulski “friended” using the profile.

Eventually the boy considered himself the boyfriend of the girl Regulski created.

A stream of messages flowed between the pair with Regulski eventually asking the boy for naked photos of himself, which he provided.

Regulski began to get hostile over the boy’s reluctance to send more explicit photos, the youngster relenting after the defendant threatened to stop being his “girlfriend”.

Judge Harbison said it appeared Regulski began his offending even before she had sentenced him in 2011 on other child sex matters from September and October, 2010.

The 2010 cases relate to charges of using a carriage service to try to engage in sexual activity with a child under 16.

The second federal charge Regulski faced yesterday related to contact with a 10-year-old boy in Western Australia.

Regulski met the boy online while playing a Playstation game called Modern Warfare 3.

This time, Regulski did not hide his identity.

After the boy got an Apple iPad for his birthday, Regulski began a relentless, seven-week campaign, largely via Skype, to get the boy to take photos of himself to send on — at first in his underwear and then naked.

The boy was promised and later given user credits by Regulski for the Playstation game.

Regulski eventually demanded more sexually explicit photos, threatening to send the photos he already had to the boy’s friends if he refused.

The possession charge related to 646 child pornography images and 126 child pornography videos found on Regulski’s phone.

Regulski was assessed yesterday afternoon to gauge his suitability for a possible three-year term in youth detention.

He will be sentenced at a later date.
