41. I do not accept these conclusions at all. Mr Phillips was not called, and I had no opportunity of hearing from him as to how he would explain and justify his conclusion, particularly his assertion that the holding falls into some sort of "no mans land". As I have said, the issues of proliferation of rural houses and rural subdivision have been very live policy issues in relation to rural planning for decades. There are some old and fallacious "chestnuts" frequently trotted out in relation to the discussion of such issues. One of the oldest of such fallacies is to say that a piece of farming land has to be a sustainable and viable farming unit, standing on its own and alone from other land, before it can be considered as useful farming land worth preserving from the harmful effects of the proliferation of rural houses and the fragmentation of farming land into small pieces. The size for a viable farming enterprise varies greatly throughout Victoria and is dependent on many factors such as soil, topography, water supply, rainfall, suitability for various particular forms of farming and so on. The size for viability in this sense is tended to increase over the second half of the 20th century. Fifty years ago a dairy farm of 15 to 20 hectares on fertile soil with favourable topography and good rainfall might well support a family dairy farm. I doubt that this would be so today. However, the sleight of hand involved is to suggest that all of the viable farm undertakings has to be in one piece. Many viable farming undertakings involve more than one piece of farmland, not necessarily contiguous one with another. If this allotment is not a viable farm standing alone, it does not follow that it is not a useful and valuable piece of farming land capable of being a useful and valuable adjunct to a farming undertaking on other land. If the anti-house proliferation and rural fragmentation policies were only to apply to existing contiguous viable farms, there would only be a relatively small proportion of farming land in Victoria to which they would be relevant. That argument would suggest that such policies are already defeated in relation to much farming land, but that is not the case. The policy still applies and are still important. This piece of land, so far as the evidence in this case shows, is quite a good example. It may be disadvantaged somewhat, from a farming point of view, by having the partly constructed house on it, but its usefulness is not destroyed by that circumstance. It may be further disadvantaged by a second house, but again grazing value remains.
