The two victims fled the scene.
Hura told police he had been angry and frustrated over the actions of boy racers in his neighbourhood and was nearly involved in a crash with a vehicle driven by one of the two men he had punched.
His lawyer, Melissa Russell, said Hura had continually had trouble with boy racers and was at his wits' end with their behaviour.
She said her client has had no history of such offending.
Judge Greg Davis said he struggled to understand why Hura didn't call police if he was concerned about the actions of boy racers.
Ms Russell said police had been involved in the past but not on the day of the incident.
The judge said Hura had two issues - his inability to call police and his decision to take matters into his own hands. He sentenced Hura to 12 months' supervision and directed that he attend anger management courses.
