Hamill, 27, pleaded guilty to a string of offences including arson and grievous bodily harm in Brisbane District Court on Wednesday, two years after his arrest while “out of control” on drugs.

Hamill was admonished by Judge Leanne Clare for his “cowardly” attacks on two motorists in the space of four days after weeks spent stealing luxury cars in southern Queensland’s Redland Bay area.

Hamill targeted his first road rage victim at Mount Cotton in April 2020, tailgating and swerving toward the vehicle before eventually confronting and punching the driver.

The driver – who also suffered a chipped tooth – spent two nights in hospital having metal plates fitted and still endures intense facial muscle pain.

The man is also nursing psychological scars.

In a victim impact statement read to the court, the man “remains incredibly angry at the world” and is seeing a psychologist after at one stage becoming suicidal following the attack.

Days later Hamill targeted a motorist on his way to work.

He almost collided with the vehicle on a roundabout before cutting the motorist off after following him into his workplace car park.

Hamill threatened the man with violence if he called the police while trying to get him out of the car before leaving when workplace security arrived.

“In each case your conduct was cowardly,” Judge Clare said.

“It was deliberately dangerous behaviour. You were using the car as an offensive weapon.

“In each of those cases the facts suggest that you actually enjoyed and took some pleasure in causing those people to suffer.”

Judge Clare said it capped a “month-long spree of lawlessness” in which Hamill broke into houses to steal luxury cars, at one stage ransacking a home while a young family slept.

Hamill seriously damaged the stolen vehicles, even destroying a BMW by setting it alight, before launching the road rage attacks.

“Those things indicate that over the space of a month your conduct … was out of control, it just became worse,” Judge Clare said.

At the time Hamill was on parole after punching a passenger on a Russell Island ferry in October 2019.

Hamill had been introduced to methamphetamine by his abusive father as a teenager and was “spiralling out of control” on the drug following the loss of his partner’s baby, defence barrister Chris Wilson said.

The father of four was sentenced to five years and six months behind bars, but will be immediately eligible for parole after serving two years in custody.
