Police have crushed plans for a large-scale drug farm in far north Queensland, complete with a camp that could have sustained workers for months.

A Queensland drug network was preparing to farm a huge multi-million dollar cannabis plantation in the state’s far north with 50,000 seeds seized in a police raid.

Police say the would-be farmers were well organised and had established a camp stocked with enough food to last for months on the isolated property

The network had spent 16 months preparing to plant vast crops, even stealing tractors and other farm equipment from nearby properties and painting them green so they wouldn’t be spotted.

When officers raided the farm, near Mount Garnet southwest of Cairns on May 11, a tract of land had already been ploughed in preparation for the first crop.

“The camp site was established with a view of sustaining life up there for a period of time. They had enough food for months,” Detective Acting Senior Sergeant Adam Golding told reporters on Tuesday.

“The potential for something like that is in the millions of dollars.”

Seven men are facing more than 100 charges after police raided the Mount Garnet property and others in the Cairns, Townsville and Mareeba areas.

Officers found the seeds, along with $175,000 worth of stolen property, including weapons and the farm gear.

The raids were the culmination of a long-running police operation focused on organised crime.

The men are facing charges including drug possession and supply, weapons and property offences. They will all face the Townsville and Mareeba magistrates courts in the coming months.
