LAWYERS for the Australian woman facing the death penalty for allegedly smuggling drugs into Bali will this week request a meeting with consular officials in a bid to seek help from Australian authorities.

The move by Schapelle Leigh Corby's defence team comes as Bali drug squad police today plan to transfer a brief of evidence against her to prosecutors – indicating that her trial could start within months.

And yesterday Ms Corby's Bali-based sister, Mercedes, came to Denpasar's Polda police headquarters jail to visit her sibling, along with two small children and another female friend.

They brought food and drinks – but were unable to get nearer to Ms Corby than shouting to one another through the cell bars.

Earlier Ms Corby, who has been in the jail since her arrest three weeks ago, shouted from her cell to the media: "I can't say anything."

And her sister Mercedes, frustrated by press waiting at the jail, told Ms Corby: "You can't come out of the cell because of all these people here. Just stay in there."

Bali drug detectives have confirmed that they intend to recommend to prosecutors, as part of the dossier of evidence, that Ms Corby, 27, be tried under Indonesia's tough narcotics law No. 82, which carries the maximum death penalty for drug importing.

But deciding which laws to use is the job of prosecutors, who will today begin assessing the strength of the case contained in the dossier.

Meanwhile Ms Corby's lawyers are working hard to build a defence that the 4.1kg of marijuana found in her luggage did not belong to her and must have been planted.

They say they need assistance from Australian officials in Indonesia in order to have their own independent tests conducted on the drugs and that before the Australian Federal Police can get involved there must be a request from the Embassy.

But lawyer Lily Lubis said that so far they had not received any positive response to the request nor to requests for information from Australian Airlines on the weight of Ms Corby's luggage when she checked in at Brisbane airport.

"We did contact the AFP through the consulate but we are still waiting for their response," Ms Lubis said.

"Now we have to prove that it (the marijuana) does not belong to her. She does not know how it can be in that bag She doesn't accept that it is hers."

Advocating Ms Corbys innocence, Ms Lubis says that even she finds the case against the Gold Coast beauty therapy student unbelievable given that the drugs were in no way hidden inside her unlocked body board bag.

"Do you think somebody can be that stupid, can be crazy? I dont know what to say but for me it is unbelievable," Ms Lubis said.

The defence wants independent forensic tests on the THC content or strength of the marijuana in a bid to prove if it originated from Australia or Bali.

Bali's chief narcotics detective, Lt-Colonel Bambang Sugiarto, said the dossier contained statements from nine witnesses, including her two female friends and younger brother, who was with her on the flight to Bali.

There were also statements from the customs officials who discovered the drugs at Bali's international airport, together with those of forensic experts.

Lt-Col Sugiarto said no fingerprint tests had been conducted on the vacuum-sealed plastic bag containing the drugs because too many hands had touched the bag after its discovery.

After the dossier is handed over, prosecutors have two weeks to assess its contents. If they want further investigations made, they can return it to police for another 14 days.

The large bag of marijuana heads was found inside Ms Corby's bodyboard bag on October 8, after she arrived on an Australian Airlines flight from Brisbane to Sydney to Denpasar.

She had been planning a two-week stay in Bali, where Mercedes was celebrating her 38th birthday.
