Synergy Gray Professional Services boss Anthony Gray extradited to Queensland

A Brisbane man accused of overseeing a $12 million investment was remanded in custody on Saturday after being extradited from New Zealand, to reappear for mention on April 1.

Anthony David Gray, 54, was charged with 25 counts of fraud, relating to a property investment scheme run by his Gold Coast-based business.

Synergy Gray Professional Services ran from 2007 to 2017 with investors allegedly told they would receive a high rate of interest for funding short-term bridging loans to property developers in New Zealand, Singapore and Hong Kong.

Two of the 25 were allegedly defrauded of more than $2 million each.

"These investments did not exist, and the funds invested were diverted and used for the personal use of the alleged offenders," he said.

Gray allegedly told investors he was a solicitor and registered financial advisor, but he was unlicensed and his practising certificate with the Queensland Law Society had lapsed.

The scheme was based on short-term bridging loans, which Gray allegedly claimed was secured by real estate with capital and interests guaranteed, the summary of facts said.

Mr Gray's 72-year-old female business partner from Hamilton faced court in Brisbane on February 25 charged with nine counts of fraud.

Detective Senior Sergeant Paskin said the Financial and Cyber Crime Group were now investigating another six complaints, and further charges could be laid, Nine Entertainment reported.

None of the money has been recovered.

The alleged victims were either known to the offenders, or referred to the offenders by persons who knew them, Detective Senior Sergeant Paskin said.

They would see some alleged return on their investment via an allegedly fraudulent statement.

The victims came from across Australia as well as the US, UK and Europe.

Gray left Australia in February 2017 to flee creditors.

Appearing in Tauranga District Court, Gray did not oppose extradition to Australia to face the charges involving an alleged Ponzi-type investment scheme.
