NSW Police have raided a home in Googong where they seized more than 300 cannabis plants and arrested a man allegedly trying to hide in the roof.
Strike Force Airts began investigating the alleged commercial-scale cultivation of cannabis in the area last month.
Officers raided a home on Erskine Loop in Googong at about 4 pm on Tuesday (16 August) and allege they discovered a sophisticated hydroponic grow house featuring 11 grow rooms and cannabis plants at various stages of growth.
The 300 plants, dried cannabis, hydroponic equipment, electronic surveillance equipment and more than $20,000 cash, alleged to be the proceeds of crime, were seized.
Police said the plants will be destroyed.
During the raid, police arrested 37-year-old Thong Van Ha after he attempted to hide in the roof cavity of the property.
He was taken to Queanbeyan Police Station and handed charges over his alleged involvement, such as cultivating a commercial quantity of a prohibited plant, possessing a commercial quantity of a prohibited plant and dealing with property that is the proceeds of crime.
Mr Ha appeared in Cooma Local Court on Wednesday (17 August) where he did not apply for bail and it was formally refused.
A Vietnamese interpreter will be required for him when he appears in the same court on Friday (19 August). No pleas were entered.
Police are continuing to investigate the incident.
