A 26-year-old man has been arrested and charged after police located more than $23 million worth of cannabis at a property in Coominya, north-west of Brisbane.
Drug squad detectives found 19 70-metre-long greenhouses containing almost 3,000 cannabis plants, more than 1,500 seedlings in hydroponic growth rooms and almost 33kg of dried cannabis while executing a search warrant earlier this week.
Police allege the discovery is linked to an alleged national syndicate producing and supplying the illicit drug across multiple states and territories.
Detective Inspector Brad Phelps said the investigation is ongoing, but the seizure is a "significant disruption to an organised crime syndicate".
"It was a large-scale production facility that had been set up on this property for the sole purpose of producing cannabis," he said.
"This particular crop we can value at over $20 million on the street, but they can produce three or four of those crops in any given year from the same site."
A man was arrested in Heathwood on Thursday in relation to the seizure.
He has been charged with producing a commercial quantity of a dangerous drug and is expected to appear at Richlands Magistrates Court next month.
Detective Inspector Phelps said police are looking to speak to several other people in relation to the investigation and urged anyone with information to come forward.
"These production processes are extremely large," he said.
"They take a lot of human and physical resources to establish and then continue to operate, so it's very hard for them to do it without coming to the notice of the locals who live in these areas.
"We really rely on the public, they are our eyes and ears in those areas, to come forward."
