The sister of convicted drug smuggler Schapelle Corby has called for an Australian Federal Police investigation to disprove claims her father Mick Corby owned the marijuana that led to the former beauty therapy student's 20-year Bali jail sentence.
Convicted drug trafficker, Adelaide man Malcolm McCauley, has told Fairfax he supplied Mr Corby with marijuana and Schapelle knew how the smuggling operation worked.
"I don't want to lie any more," Mr McCauley told The Sun-Herald.
"It's time to wipe the slate clean. Tonight I want to sleep with a clear conscience. Once the drugs were delivered to Mick, I had nothing else to do with them whatsoever. But certainly I knew where they were heading."
Mr Corby died earlier this year from cancer and a week ago Queensland Police said they had "no evidence to link Michael Corby with involvement in the drug trade".
Speaking from Bali, Schapelle's sister Mercedes Corby told AAP she was outraged by Mr McCauley's claims.
"I call on the federal police to do a full investigation into his allegations as this will clear my dad's name," Mercedes said.
"This man is a self-confessed and convicted drug trafficker."
Schapelle Corby is serving a 20-year jail term in Bali's Kerobokan prison after being convicted in 2005 for smuggling 4.2 kilograms of marijuana in a boogie board bag into Denpasar airport.
"I met Mick around 2000 through a mutual friend who was involved in shipping hooter (marijuana)," Mr McCauley told The Sun-Herald.
"Originally, I grew the stuff myself, but I was never that successful. I was much better as a broker - buying and selling.
"I was always on the lookout for new business. Then this particular friend informed me one day he was about to pack it all in ... so I said: `please mate, can you put me in touch with the person you're selling to?' He was supplying to Queensland, to Mick Corby."
Mr McCauley said the marijuana was "excellent South Australian hydro" with "an excellent reputation in Bali".
The cannabis was packaged with a series of $1,000 bribes to help it move through customs, he said.
"And the simple reason why it broke down on the day was because the money was no longer in the bag when it arrived with security," Mr McCauley said.
Mercedes Corby said her father loved his children and would never let them take the wrap for something he had done.
"Schapelle was his baby girl. There's no way on earth he would let her go to jail for something he did," she said.
"My dad was a good man. These claims are making an easy target of a dead, defenceless man and there is absolutely no basis for these allegations."
Mr McCauley was linked to the Corbys in 2005 after he was photographed visiting Schapelle in the Bali prison.
A subsequent police raid of his Adelaide home found 15kg of cannabis, thousands of dollars in cash and the photos showing him with Schapelle in Bali.
The Corbys deny knowing Mr McCauley prior to his visit to Bali in 2005.
Mr McCauley was released from prison in May this year and is believed to have been offered up to $60,000 by media outlets for his story about the Corbys.
Mr Corby's cousin, Allan Trembath, told ABC TV's Lateline this month that Mr Corby had been involved in moving marijuana throughout Queensland for decades.
He said Mr Corby had offered him $80,000 to accompany him on a boat trip to Cape York to pick up marijuana.
"My sister is innocent. We will never stop saying that as it is the truth," Mercedes said.
