Bush cook books

Does anyone have any recommendations about bush Cookbooks and indeed are they even worth having? Looking at "Aust Bush Cooking Book" or "Outdoor Cook Book Viv Moon". Anyone familiar with either or both and have any general comments on this: ie are they more taylored to someone cooking over open fires etc.... we have general knowledge of barbecuing and extensive knowledge of cooking using "conventional methods".
Cheers & happy new year to all.
