My neighbour has a large block of land and has begun using it as a car wrecker yard. They are continuously revving high-powered engines and the noise is very annoying. Yesterday they installed a 20m high pole, with floodlights and CCTV cameras, which is not only an eyesore as it looms above all trees. but also creates a blinding light in our back yard at night. I'm also worried about the surveillance cameras as they may be used to determine when a property owner is home (the relevant property is surrounded by private homes and is in a residential zone). I've asked the neighbour to tone down the noise previously and he has been abusive and threatening. I've complained to the council (Devonport, Tasmania), with a resulting demeaning platitude and no result. Can anyone tell me the appropriate legal authority which has jurisdiction over this matter? And which will investigate? I have photos.
