A convicted drug trafficker says he will tell the inside story on Schapelle Corby's arrest, but only when the courts have finished dealing with him.
Adelaide man Malcolm McCauley was convicted and sentenced to three years' jail for his role in a drug syndicate that carried 100kg of cannabis from South Australia to northern Queensland between January 2004 and November 2005.
His role was to recruit couriers and supply cannabis for the syndicate.
He was released from prison last month.
In an interview for the Nine Network documentary, Schapelle Corby: The Hidden Truth, aired on Tuesday night, Mr McCauley indicated he knew how the marijuana came to be in Corby's bag.
"It landed in Denpasar and she got caught and she admitted that it (the bag) was hers," he said.
"What happened in between is a good story and the truth ... I had nothing to do with it, believe me.
"How it happened is probably for another day."
Mr McCauley said he would one day tell his story.
"Give me 18 months, and I will tell you. I will be over the courts, then. Double jeopardy and everything. I had nothing to do with it. You can take that as gospel."
Mr McCauley was at the centre of another sensational twist in the Corby case.
Photographs of he and Corby, taken in the jail in Bali after the trial, later turned up in a police raid on his house, sparking further rumours that Corby had been linked with the drug trade.
In the documentary, Corby's mother Rosleigh Rose said she met Mr McCauley and his friend, Dave McHugh, in an Adelaide hotel after Corby's 2004 trial.
During a conversation, Mr McCauley asked if they could meet Corby when they later visited Bali, she said.
But Mr McCauley said he and Mr McHugh met Corby much earlier, during her trial.
Footage recorded by the film-makers shows Mercedes Corby thanking Mr McCauley for attending the hearing. It also shows he, Mr McHugh and Schapelle Corby chatting as she stood in a holding cell.
"Dave and I went to the court and Ros was there, and she thanked us both - and Mercedes, the sister - thanked us for the support," he said.
Corby and her mother deny knowing them before the trial.
"I didn't know him (Mr McCauley) and it was just a person who came to court to support me at court, met my parents. They just seemed like normal people," Corby said.
Corby, 30, was convicted in 2005 for smuggling 4.2 kilograms of marijuana in her boogie board bag that was discovered at Bali's Denpasar airport.
She maintains her innocence, but is serving a 20-year sentence in Bali's Kerobokan prison.
The Queenslander's final legal challenge failed in March when Indonesia's Supreme Court upheld her 20-year sentence.
An appeal for clemency to Indonesia's president is Corby's last legal option, but it means she would have to admit guilt.
Her hopes of being released from prison have relied on the outcome of long-running negotiations between Indonesia and Australia over a prisoner transfer deal.
Corby was hospitalised on Friday afternoon suffering severe depression.
