Bandidos motorcycle gang member Leslie David Gadd pleaded guilty in Brisbane's Supreme Court last week to the attack on 40-year-old Jason Enrique Gravestein.

Gadd, 43, had been due to stand trial for attempted murder of Mr Gravestein, but entered a last minute plea to four lesser charges relating to the incident at Little Mountain in April last year.

He was charged with wounding with intent, assault occasioning bodily harm while armed in company, armed robbery in company with violence, and burglary by breaking while armed and in company.

His sentence was adjourned until Wednesday, when the court was told Gadd and an unidentified accomplice donned disguises and entered Mr Gravestein's home to search for drugs and cash.

When Mr Gravestein and his long-term partner arrived home, the two men launched their attack.

Prosecutor Phil McCarthy told the court Gadd pushed Mr Gravestein to the ground and then shot him once in the thigh while demanding cannabis and money from the safe in the bedroom.

Mr Gravestein handed over about half a kilo of cannabis and around $2000.

The men continued their struggle, which ended when Mr Gravestein escaped and ran outside.

Gadd was arrested a short time later.

Justice James Douglas agreed to the crown's submission that Gadd's actions be declared serious violent offences, meaning he must serve 80 per cent of his sentence before he is eligible for parole.

He has already served 579 days in pre-sentence custody.
