Man i no what you maen ,when i lived in melbourne .I had a crop in the back yard in the suberbs two double story houses on both sides and yes i was in the flight path for the police helicopter was a bit of a task.Every now and then they would come over very low,use to make my heart jump a bit.Dont wory they are usualy looking for someone.I had a scanner.
Also the power companys in Australia are all privatly owned,i recon if you ask them they will tell you to set up another grow room.You will become there most valued customer.Just pay your bills as soon as they come in...Good luck..
