Schapelle Corby's half-brother has denied he was the courier of the drugs she was found guilty of smuggling into Bali.
James Kisina, 20, was with Corby on October 8, 2004 when she was caught at Denpasar airport with 4.1 kg of marijuana. Malcolm McCauley, the South Australian man who says he supplied the drugs to Corby's late father, Mick, has alleged Kisina was the "carrier".
McCauley said a foolproof "arrangement" with corrupt Balinese officials broke down that day because Kisina had "pocketed" the agreed $US1,000 ($A1,029) bribe.
The Sun-Herald newspaper says that when it spoke to Kisina at his mother's Brisbane home last week he denied he was the courier on the run.
"It's not true. I was just there for a holiday," he said.
When asked if he took the bribe out of the boogie board bag, he said: "Sorry, mate, I wouldn't know anything about that."
In an interview with The Sun-Herald last week, McCauley revealed how he had supplied hydroponic marijuana to Mick Corby since 2000.
McCauley was arrested in November 2005 when a police raid on his Adelaide home uncovered evidence of his trafficking, as well as pictures of him visiting Schapelle Corby in jail.
McCauley walked free from a Queensland prison in May having served 15 months for his part in transporting 100 kg of cannabis from South Australia to Queensland.
He said while he had nothing to do with the drugs once they were with Mick, he'd always known "where they were heading, and how".
He told the paper that a "well-oiled machine" had been in place for years, involving Mick and crooked Bali airport security personnel who would "pocket bribe money placed inside the bag" in return for allowing the drugs through.
He said Schapelle "knew her dad was a drug dealer", knew about the trips to Bali, the bribes, "the lot".
He said the reason the bribe system failed that day was because there was "no payment". "Mick didn't forget it," he said. "The money was in there, all safe, signed and delivered - almost delivered.
"It wasn't in there for the simple reason that James decided to pocket it prior. That's a fact. He took it. I know that. You can quote me on that. And I'd like to see you quote that."
McCauley said the drug-filled bags often sailed through Bali airport security with the $US1,000 ($A1,029) bribe still inside, adding: "You might fluke it and then it would be pocketed, depending on who was couriering it."
But McCauley said of Kisina: "He got greedy. It was his job, but when it came to (customs asking) "is that yours?" she (Schapelle) grabbed it off James. She presumed (the money) was in there."
