The Australian Federal Police (AFP) has ruled out any fresh investigation into the case of convicted drug smuggler Schapelle Corby.
This follows claims that Corby's father owned the marijuana that led to her 20-year Bali jail sentence.
Corby's sister Mercedes had called for the AFP to disprove allegations from convicted drug trafficker, Adelaide man Malcolm McCauley, that he supplied the late Michael Corby with the drugs.
Mr McCauley also told Fairfax newspapers that former beauty therapy student Schapelle knew how the drug smuggling operation worked.
"The Australian Federal Police does not intend to investigate claims by an Adelaide man that he was involved in the supply of illegal drugs to a member of the Corby family," an AFP spokesman said yesterday.
"Schapelle Corby was convicted of drug offences in Indonesia where she is currently serving her sentence.
"The information published in today's (Sunday's) media reports does not create grounds for further investigation."
Schapelle 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.
McCauley said the plan "broke down on the day" because a series of $1,000 bribes also placed in the bag went missing before the bag went through airport security.
Speaking from Bali at the weekend, Mercedes Corby told AAP she was outraged by Mr McCauley's claims and wanted an AFP investigation to clear her father's and her sister's names.
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".
A spokeswoman for Queensland Police said yesterday the matter was not under investigation.
