Mudgee hunter, pretty spot on. The one aspect that is important is openness and honesty. I have seen so many areas that have become completely off limit because of greed. Gold fever for a lack of a better description. People who jump fences or 'moonlight' ruin it for so many, when all you really need to do is have a presentable appearance and an open disposition.
Most, or many land owners are relatively conservative, so your neck or face tattoos might not be helpful, as well as your dogs, and some of the stickers on your car.
Use a little common sense. If you are a ********, you will be shown the gate, but if you are genuine, and exude a pleasant confidence you have a good chance of being accepted.
