Lako Eludas Rasas, 26, approached a man in Brisbane and broke his thigh bone

A refugee who was given asylum in Australia so he could start a new life has been found guilty of repeatedly attacking locals.

Lako Eludas Rasas, 26, faced Brisbane District Court on Monday and pleaded guilty to grievous bodily harm, obstructing police and being a public nuisance.

The court heard how he had approached a man outside Roma Street Station in Brisbane and pushing him so hard he broke his thigh bone, NT News reported.

The victim underwent surgery to fix his leg and hip, but spent an additional two weeks in hospital due to complications.

Rasas had only been out of police custody for two weeks when he committed the crime.

Judge Julie Ryrie sentenced Rasas to 2.5 years in jail, and told him to get his life under control.

'You will keep going to prison if you don't take control of your life,' she said.

'The victim of your assault provided no provocation to you.

'Yet you were persistent as he tried not to engage with you — he turned away from you but you chose to push him to the ground.'

Rasas moved to Queensland from Sudan 17 years ago after witnessing extreme acts of violence in his home country and in a refugee camp where his brother and sister died.

He was constantly in trouble with the law in Darwin and Brisbane after repeatedly bashing residents and becoming a public nuisance.

Rasas was previously jailed in Darwin in 2017 for bashing and robbing the president of Territory's Congolese Community organisation, and attacking a teenager with a machete (stock image)

Judge Ryrie acknowledged the man's experiences as a child, but said he had to learn to control himself as an adult.

Rasas pleaded guilty to grievous bodily harm, obstructing police and public nuisance.

He will be eligible for parole in November.
