The family of convicted drug smuggler Schapelle Corby has fired lawyers acting for her half brother in Queensland.

Solicitor Mark Howden of Howden Saggers Lawyers on Monday said the firm was no longer representing Corby's half brother James Sioeli Kisina, 18, of Loganlea, south of Brisbane, but would not elaborate.

Kisina faced court earlier this month over his alleged involvement in a violent home invasion during which a couple was attacked with an iron bar and menaced with a machete before a large quantity of cannabis and cash was stolen.

Police alleged the stolen drugs and money were later found at the Loganlea home of his and Corby's mother Rosleigh Rose.

Mr Howden confirmed he had been sacked by the Corby family but would not elaborate.

"That's right, we are no longer acting for him," Mr Howden said.

"I can't make any further comment."

Kisina also rejected police allegations, outlined in an affidavit, that he was involved in the exportation of cannabis.

His former lawyer Stefan Simms, also of Howden Saggers Lawyers, said Kisina was not motivated by crime when he allegedly broke into the Rochedale house, south of Brisbane.

He said Kisina had learned the property's occupants were allegedly well known drug dealers and could have information helpful to Corby's bid to have her drug smuggling conviction in Bali quashed.

Kisina is due to face the Beenleigh Magistrates Court again on March 8.

Corby is serving a 20-year jail term in Indonesia for smuggling 4.1kg of marijuana into Bali.

The 28-year-old Queensland woman was arrested on October 8, 2004, when customs officers at Bali's airport found the marijuana in her bodyboard bag after she stepped off a flight from Australia, accompanied by Kisina.

SCHAPELLE Corby's diamond-wearing, gun-toting Jakarta lawyer has quit her no-fee case, saying he needs to make quick cash to buy a fast new Ferrari.

Hotman Paris Hutapea's announcement comes just days after Indonesia's highest court threw out an appeal he had filed against her drug-smuggling conviction and raised her jail term.

Mr Hutapea said yesterday he had been volunteering his time to defend the 28-year-old Gold Coast woman and needed to devote time to paying clients.

"I want to buy the new model Ferrari. So, I have to make more money now," said the self-proclaimed playboy who wears flashy jewellery and carries a pistol.

"I'm getting bored of all my old cars", including one of the traffic-choked Indonesian capital's few private U.S. military-like Hummers.

Mr Hutapea joined Corby's legal team late last year, not long after she was convicted.
