Police have seized about 6.2kg of cannabis, a quantity of cannabis plants and shortened firearms in searches of two properties in the state's North-West.
Police will allege 'grow rooms' and equipment for cannabis production were also located at the properties at Kindred and in Devonport.
The 6.2kg of cannabis seized equates to about 2500 street deals.
A 30-year-old man from the North-West has been arrested and charged with several firearms and drugs offences, including trafficking in cannabis and possessing unregistered firearms.
