A MELBOURNE-based German citizen is the latest foreigner to be charged with drug offences in Bali.

Patrick Guy Prinzler, 34, whose last known address was Queens Rd, is in a Denpasar jail accused of having 0.7g of hashish in his pocket.

Mr Prinzler, who was holidaying in Bali, faces a maximum 10-year jail term for possession of illegal drugs.

Police said Mr Prinzler was arrested late last week in the upmarket area of Seminyak after a tip-off.

Police Major Ady Soeseno said officers were still investigating the source of the hash.

Lt Made Pakris said Mr Prinzler told police he received the drugs from an Australian whose identity is not known.

Adelaide man John Pyle was arrested in May and police found 1.8g of hash at his home in the mountain resort village of Ubud. Mr Pyle is in jail with a trial date yet to be set.

A ninth and final member of the Bali nine alleged heroin smuggling ring is expected to ask the Federal Government for legal aid within days.

A well-placed source confirmed the looming development yesterday amid speculation the bill to taxpayers could top $1 million.

Eight of the suspects have already applied for legal aid under a special fund for Australians charged with offences overseas.

The Bali nine face the death penalty or life imprisonment when their trials start within weeks.

A leading Melbourne barrister yesterday said overall legal costs for defending the suspects could easily top $1 million.

The barrister, who did not want to be named, has represented Australians charged with serious offences overseas.

Costs would run into tens of thousands "at a minimum" for each of the Bali nine, who had to be separately represented to avoid any conflicts of interest.

"If the facts are not really at issue then it might only be a week or two's work prior to trial," the barrister said.

"But the question is whether the trial going to go for days, weeks or months."
