Simeon Brieffies pleads guilty to illegal firearms, stolen vehicles in Rockhampton

An electrician busted with a stolen motorbike while visiting the grieving family of alleged shooting murder victim Anuisha Bone has given a surprising excuse for his latest stolen property and gun charges.

A man busted with a threaded barrel firearm and a silencer claims a stolen ute was given to him for farm work and a stolen truck loaned to him for moving.

Simeon Levi Brieffies, 35, fronted Rockhampton Magistrates Court for charges related to illegal possession of firearms, two of receiving tainted property, and one for driving while his license was suspended by the State Penalty Enforcement Registry.

He’d previously been sentenced earlier this year after being caught with a stolen motorbike while visiting the grieving family of Anuisha Bone who was found dead with a gunshot wound to his neck.

Brieffies is not alleged to have had any involvement in Anuisha’s death and two others are before the court charged with his murder.

Police prosecutor Claudia Neill-Ballantine told the court last week detectives searched Brieffies’ residence on April 4, 2025, locating three unsecured and unregistered firearms in a wardrobe in his bedroom.

She said one had a threaded barrel end and in an adjacent room, police located a stainless-steel silencer.

Ms Neill-Ballantine said Brieffies did not have a firearms licence.

She said Brieffies told police the firearms were old, and he used them for pest and vermin control on his property.

Defence lawyer Jess King said the silencer was fabricated by her client to avoid disturbing any of his neighbouring properties, or other stock, when he was engaging in pest management activities.

Police also located an Isuzu truck stolen from Park Avenue and a white Toyota LandCruiser stolen from Duaringa, located on Brieffies’s property.

The truck had Brieffies’s fingerprints on the driver’s door and police identified the LandCruiser from the engine number.

Ms Neill-Ballantine said Brieffies told police he had borrowed the truck to assist in moving a shed.

Ms King said Brieffies, a qualified electrician, instructed someone gave him the LandCruiser to use as a “basher” around the property and he never looked any further into the vehicle’s ownership due to the condition it was in.

Brieffies, who lives in the Stanwell area, was also intercepted driving while his licence was SPER suspended on October 17, 2024.

The court heard Brieffies was aware at the time of driving that his licence had been suspended since October 26, 2023.

This was not the first time Brieffies had been busted with vehicles that had been stolen.

During his sentencing in February 2024, the court heard he had been busted riding a stolen motorcycle in November 2023 as he gathered with friends at the home of alleged murder victim Anuisha Bone’s parents (who are also not accused of any wrongdoing).

“The deceased was a close friend of my client,” Ms King told the court in February 2024, explaining that while at the Bone family home, Brieffies received a call from another friend of Anuisha’s who was distressed about the situation.

Brieffies hopped on the motorbike, despite being aware the bike did not belong to the person who rode it to the Bones residence and rode it to be with the friend who had called.

Ms King said the recent offending was still a de-escalation for her client who had an eight-page criminal record which showed issues with substance misuse.

She also said he has addressed the issues that plagued him in the past and now worked full-time as a machine operator for a Gracemere business.

Brieffies pleaded guilty on July 18, 2025, to two counts of receiving tainted property, along with one each of illegal possession of a category B weapon, illegal possession of a category R weapon and driving while SPER suspended.

He was fined $1300 and disqualified from driving for one month.

Convictions were recorded.
