In 2017, Mayot received a sentence of up to six years in prison for the unlawful blow that led to the death of 54-year-old grandfather Lindsay Ede in Ipswich, southwest of Brisbane.

He pleaded guilty to the offence and was the first person to be charged under Queensland’s “one-punch” laws.

The landmark legislation was introduced in 2014 after a spate of violence and deaths resulting from single punches.

Judge Gregory Lynham today told Mayot he risked wasting the rest of his life if he did not stop committing violent offences.

“The offending that brings you back to court today suggests you are not a particularly fast learner,” he said.

“You remain a fairly young man. If you persist in this type of conduct … you will one day reflect as an older man and see you wasted your life because you couldn’t keep your hands to yourself.”

Judge Lynham heard Mayot had punched and put a headlock on a security guard at Mater Hospital in South Brisbane on January 21, 2023 and resisted another officer when he intervened.

The security guard who was punched by Mayot required physiotherapy for a neck strain.

Defence barrister Elise Sargent said Mayot had attended the hospital’s emergency room prior to the assaults because he thought he was suffering from drug-induced psychosis from consuming methamphetamine.

Judge Lynham said hospital security guards had a difficult enough job without having to deal with aggressive drug users.

“The (assault on the prisoner) I regard as the most serious offence … you kicked him while he was in a vulnerable position and caused not insignificant injury,” he said.

Mayot was serving a custodial sentence for an unrelated offence when he attacked a fellow prisoner in the exercise yard on June 23, 2024.

The crown prosecutor said the prisoner would have faced a “confronting experience” when Mayot attacked him.

“Mayot punched him multiple times to head, face and body. He threw him into a wall,” the prosecutor said.

“He was kneed in the body until he fell. Mayot then kicked him unconscious.

“He suffered swelling, muscle spasms, had a top front tooth chipped, a laceration to the inside of his cheek and a lower jaw fracture.”

Sargent said Mayot arrived in Australia aged six as a refugee from Sudan and was now an Australian citizen.

“His history shows he can go periods of time without committing offences of violence,” she said.

“He is not without hope. He is focused and motivated to deal with his problems.”

Judge Lynham sentenced Mayot to 18 months’ imprisonment to be released on parole immediately due to already spending seven months in custody.

Sargent said Mayot would not be released until next week as he was still due to be sentenced for a separate offence.
