**Acknowledgements**

I would like to thank my colleague, Don Boadle, for his thought-provoking input into this chapter; it is greatly appreciated and resulted in some stimulating discussion. I would also like to thank Professor D. Brunckhorst, University of New England, for allowing me to use the graph of the *Tilbuster Commons*. Neil Clark, Rural Market Development, Bendigo, deserves special recognition for being extremely helpful to find data on corporate farming enterprises. Ms Viktorija Zgela, the commissioning editor's expertise on all things technical, warrants appreciation: her thoughtful notes came at times when things were a little hectic. Last but not least, the guidance and advice of the referee / editor is also gratefully acknowledged.
