That came during Lukas Lee Hines' severity appeal on a two-year sentence handed down in Albury Local Court.

The non-parole period had been set at 14 months.

Judge Julie Baley SC said that given Hines kept offending, this was "quite a generous sentence".

She dismissed the appeal.

Baley, 24, was jailed over three incidents.

These included one on August 23, 2018, in which he broke into his ex-partner's home, smashing furniture and fittings and punching her to the eye.

"Mr Hines is a danger to the community, in particular a danger to his partner," Judge Baley said in the District Court in Albury on Friday.

"He has assaulted her on numerous occasions in the past. He's a recidivist when it comes to domestic violence. He just keeps doing it."

Judge Baley said she accepted Hines probably had an acquired brain injury from long-term substance abuse, "but there is no medical evidence of that before me".

"I think at this stage his prospect of rehabilitation is poor."

Defence solicitor Bronte Winn said Hines' brain injury was largely the result of his petrol-sniffing habit, from around the age of nine to 12.

Hines' ongoing alcohol and drug abuse problems were highlighted, as was his failure to do something about that by submitting himself to rehabilitation.

Judge Baley questioned Hines on this point after Ms Winn called him to the witness box.

She noted his first jail sentence, in 2014, when he was handed 12 months with a minimum of three months.

In response, Hines said that on getting out of jail he "just moved back ... same old thing".

He couldn't remember similar sentences from 2015 and 2017.

"You knew you weren't supposed to assault the victim, didn't you? You know that?"

"Yeah," he replied.

Hines told Judge Baley he accepted he had a substance abuse problem and would accept help.

"Coz I know, coz it's going to be different this time," he said.

"I know that it's affected her."
