A Sydney man accused of overseeing a multi-million dollar Australian drug syndicate is set to be extradited from Thailand seven years after skipping bail in South Australia.

Robert Gordon Pollybank Gee, 60, has been held in a Bangkok prison since he was arrested at a bar on the Thai resort island of Phuket in 2016.

Australian Federal Police said Gee fled to Thailand after being granted bail on a $10,000 surety.

He was allowed to keep his passport despite facing serious drugs charges relating to a 2006 South Australian police operation codenamed Crunch.

The operation recovered cocaine and methamphetamines worth $1.2 million and $264,000 in cash.

Thai authorities said when Gee was arrested in Phuket he was in possession of a fake Canadian passport.

Gee had been listed as among Australia’s most wanted suspects.

A Thai court agreed to an Australian request to extradite Gee because his alleged crimes in Thailand did not involve politics or military-related activities.
