It depends where you are. If you're in the upper middle class neighborhood you can probably get away with it. People will think you're brewing your own alcohol or some other eccentric hobby. If you do this in a poor neighborhood that's had a problem with meth houses, you'll, either get the police kicking down your door, or you'll get the methheads breaking in and stealing your equipment. Trying to compare what happens in the AU vs US might not work out well.
