A series of grow houses, purpose-built for producing hydroponic cannabis, have been raided as part of a six-month operation in south-east Queensland.

In raids yesterday and this morning, 240 officers from Queensland Police, Border Force and the Australian Crime Commission searched 27 properties, including 20 homes and allegedly found more than 3,000 plants.

One property raided was a warehouse at Acacia Ridge in Brisbane’s south.

Police said the operation also resulted in the seizure of 45 kilograms of dried cannabis and cocaine with a street value of approximately $20 million along with a significant amount of cash.

A total of 36 people have been charged with more than 100 offences.
