Water, water, water
I'd just like to mention water. Seeing we are experiencing drought/fires/high temps/wind in a large part of our country, just how important water is. I believe it's super important to plan for water storage, water availability when setting up, buying or refurbishing your house, farm, land etc. I live in what was once considered a safe rainfall area, roughly 1500 mm/ yr or 60 inches. We have 140,000lt rain tank capacity, 3 dams and a bore. We don't farm any stock and have a reasonable sized veggie garden. We are very water conscious, it is a special commodity. It makes me feel safe, knowing we have that resource, to keep our veggie garden watered, for fire protection and to keep alive trees and shrubs we've planted in recent years. Our once permanent creek is dry, our dams have dropped to the lowest levels we've seen. Our drinking water/house supply is still at healthy levels and our bore just keeps on giving and for that I am truly greatful. Always remember that it doesn't matter what sort of farming one does, you are in a hopeless situation without this wonderful resource.
