Been many a Robbie used to transport cannabis around Far North Queensland, I should know.
My machine was used by a grower on cross hire some years ago. !! I ended up being a witness for the prosecution and had to produce the Maint release etc showing the Pilots signature, The Dope " pun intended " even left the flight plan and VTC under the seat showing were the plantation was located..
Turned out the guys were packing the dope into 1KG packs under the seats and landing on a dirt road to then end up on a cattle truck and moved interstate.
