Man from Adelaide’s southern suburbs makes another bail bid after allegedly threatening Glenunga students, Jews, Gather Round, Fringe

A “master hacker” has made another bid for freedom after he allegedly made a series of threats, including to boil Adelaide high school students in oil.

A skilled hacker with a “mastery of computers”, who allegedly threatened to attack, bomb and boil students of Glenunga International High School has made another bid for freedom.

The man applied for home detention bail in the Supreme Court on Friday, after he also allegedly threatened to contaminate food items and target Gather Round.

His name remains suppressed after a joint application by both counsel for the order to remain in place, as investigations are still ongoing.

During the man’s unsuccessful bail bid in May, the court was told he had allegedly:

DECLARED himself a prophet and a hero, telling the school it could choose between violent and non-violent futures;

REPEATEDLY contacted an Advertiser journalist and made the same threats toward the school, which were immediately passed on to police;

HACKED the school’s data systems and stored information there while questioning its ability to keep students safe;

WARNED he would attack the school with a car and boil a female student in oil;

EXPANDED his threats to target members of the Jewish community, Gather Round fixtures and Fringe festival events;

THREATENED to inject lead acetate into yoghurt, brownies and jellies;

CLAIMED he had been conducting “experiments on people” to determine whether the substance could be tasted once injected into foods;

FURTHER claimed he had practised how to sever a human’s brain stem and cut their thighs;

DEMANDED $23 million in “Bitcoin and cash” in order to bring about the nonviolent future; and

BEEN arrested after unknowingly engaging with an undercover police officer online.

The man has yet to plead to two counts of blackmail and one count of making it appear goods had been, or were about to be, contaminated.

Finally, it is alleged the man “caused public alarm or anxiety” by making it appear “yoghurt, brownies, juice jelly, hot cross buns and apples had, or were about to be”, contaminated with lead acetate.

The court heard Glenunga International High School received a series of “threatening” emails from the man between November 2024 and February 2025.

“The man called himself ‘the prophet of justice’, a ‘hero to cleanse and renew the corrupt institution known publicly as Glenunga International High School’,” a police prosecutor said.

The prosecutor said the man then began emailing other places, including The Advertiser, before saying an attack “was planned for SA and its Jews”, Gather Round and the Fringe.

She said the man had a high level of “cyber skills”, was “technically proficient” and had a “mastery of computer systems”, having previously hacked the school to store information.

On Friday, Jessica Houlahan, for the prosecution, told the court there were no items related to explosives found after a search of the man’s home.

The court heard it was yet to be ascertained whether the man had been acting alone.

James Caldicott, for the man, told the court his client intended, if allowed by his community corrections supervisor, to work and study at university if he was granted bail.

He said there were concerns for the man’s mental health and they were looking at obtaining a psychiatric assessment.

Acting Chief Justice Mark Livesey ordered a home detention bail and adjourned the application until next week.
