PROSECUTORS handling the death-penalty case against accused Australian drug trafficker Schapelle Leigh Corby are investigating luggage handling procedures at Bali's airport.

The Brisbane woman has consistently claimed 4.1kg of marijuana found in a vacuum-sealed bag in her luggage last month was planted at some time during or after her flight there.

Balinese prosecutors also want police to re-interview the 27-year-old about her initial reaction when her bag was opened during a search at the airport, revealing the drugs.

Prosecution requests for more information regarding the luggage processes employed at Bali's Ngurah Rai international airport appear to be a bid to negate expected defence arguments that the high-grade marijuana was planted.

Ms Corby has been in custody since her arrest on October 8 at the airport after arriving on a flight from Brisbane via Sydney to the capital Denpasar.

Foreign Minister Alexander Downer says the case of a Gold Coast woman accused of taking drugs into Bali is "very curious" because cannabis is a lot cheaper in Indonesia than Australia.

Mr Downer gave an assurance that Australian authorities were doing all they could for Schapelle Corby, 27, who was apprehended on arrival at Bali airport last month in possession of 4.2 kilograms of marijuana.

She has claimed the drugs must have been planted in her luggage in Australia.

Mr Downer said there were limitations on what assistance could be provided because Ms Corby was subject to Indonesian law.

"What we are trying to do at the moment is get an analysis done of the cannabis that was found in her boogie board bag, which was over four kilograms of cannabis. That's an awful lot of it," he said on the John Laws radio program.

Mr Downer said they also wanted to examine the plastic bag in which the cannabis was found.

"If we can establish where the cannabis came from, that might or might not be of some assistance," he said.

"It is a very curious case this - cannabis is, I am told, much cheaper in Bali than it is in Australia, so why would somebody be taking a large amount of cannabis from Australia to sell in Indonesia.

"The quality (of cannabis from Australia) is apparently better. I accept that is one possible explanation, but the price difference is apparently absolutely enormous.

"I just don't know. We just do what we can for her."

Mr Downer said the case underlined the fact that Australian travellers must be very careful.

"If they do go into South-East Asia with drugs then the consequences can be very dire for them," he said.

ACCUSED drug smuggler Schapelle Corby has come face to face with terrorist mastermind Imam Samudra in the Bali prison they now share.

The chilling encounter between the 27-year-old Australian beauty therapist and the Bali bomber on death row was revealed by an Australian man who had a chance meeting with Corby inside Bali's jail.

David Hazlewood, 28, a tour leader from North Sydney and three-year resident of Bali, was approached by Corby in the visitors' hall of the Kerobokan prison where she is locked up for allegedly trying to smuggle 4.1kg of marijuana into Indonesia inside a bodyboard cover.

Mr Hazlewood, who was visiting an Indonesian friend on drug charges, spent an hour talking to Corby in which she reasserted her innocence and spoke of her one encounter with Samudra since being transferred from her police holding cell a week ago.

"She was wearing a singlet and Imam Samudra was apparently not too happy about it," Mr Hazlewood said.

"Being really hot in the jail and being in Bali, where there's no need to dress like a conservative Muslim, she was just wearing a sarong and a singlet top and his eyes just looked her up and down -- not a look of love that's for sure."

Samudra refuses to address Westerners and chose not to say anything to Corby as she walked by. The incident occurred last Friday when Samudra and 22 other convicted bombers, including smiling assassin Amrozi and Mukhlas, were brought into the yard for afternoon prayers.

Despite the unnerving meeting, Corby is apparently determined not to be intimidated.

"She said: 'Don't worry I've got plans for him. I can't tell you what it is but he won't be liking it, mark my words.'

"I've got no idea what she meant by that," Mr Hazlewood said.

Samudra, along with Amrozi and Mukhlas have been condemned to death for the 2002 blasts in Kuta which killed 202 people, including 88 Australians.

The Federal Government would provide further assistance in the case of Corby if it was able to, Justice Minister Chris Ellison said yesterday. Corby's lawyer Vasu Rasiah met with Foreign Minister Alexander Downer earlier this week.
