Dozens of witnesses for Qld fraud hearing

Dozens of witnesses will be required to give evidence in the committal hearing for a Gold Coast father and son accused of masterminding a multi-million dollar investment scam.

Jack and John Doumani will face a commital hearing starting on March 6 on multiple counts of fraud with police alleging the pair ran a "boiler room" cold call investment scam operation.

It's alleged the scam fleeced approximately $60 million from victims over a six-year period.

Jack Doumani has also been charged with operating an illegal bookmaking operation.

Doumani is a school friend of convicted drug kingpin Mokbel and allegedly operated a betting business for him on the Gold Coast.

Lawyer Darren Mahoney told Southport Magistrates Court on Monday the brief of evidence against his clients was "enormous" and the court heard 44 witnesses will be called for cross-examination.

The committal hearing is to be broken into two five-day periods.

Mr Mahoney said the first period, from March 6 to 10, will be reserved solely for the fraud matters involving the Doumanis and co-accused Christopher John Pappas and Daniel Kenneth Seymour.

A second five-day hearing, from May 2 to 8, will deal with the illegal bookmaking charges involving Jack Doumani and five other co-accused.
