An Australian property developer should be jailed for three and a half years in Indonesia after he allegedly used "trickery" and "lies" during the sale of a luxury villa in Bali, prosecutors say.

Eric Bevan Gillet, 48, was arrested in Bali in February after a property deal he struck with two businessmen in 2013 allegedly went sour.

The former president of the South Perth Chamber of Commerce, through “tricks and a series of lies” allegedly incited two men – Tommy Comerford and Ketut Semadi – to buy 10 villas in his Xanadu Lifestyle Resort complex at the popular beachside town of Seminyak.

The men are said to have lost 6.7 billion rupiah (about A$659,455) in the deal.

Prosecutor Purwanta Sudarmaji told Gillet’s trial at Denpasar District Court that the Western Australian should be jailed for three and a half years for fraud.

“There is no justification or reason (for what he has done) and the defendant must be held responsible,” she said.

“We request the judges state the defendant has been proven officially and convincingly guilty for the crime of fraud, with the intention of benefiting himself … with trickery and a series of lies.”

The prosecutor claimed Gillet was “beating around the bush” when answering questions during his trial and that it was clear he had no intention to return any money to his alleged victims.

Prosecutors allege Mr Comerford – who works for a mining exploration company – became concerned about the properties he bought off Gillet when the Australian told him that designs for the villas had changed a second time.

When Mr Comerford asked for further development documents and a contract letter for the land, Gillet allegedly did not produce them.

And so the businessman asked for his money back.

He has told the trial Gillet refused this request as well.

Gillet, who is is being held in Indonesia’s notorious Kerobokan prison, has been charged with fraud and embezzlement.
