I have done some survival training and this is what I learnt ...
... unless you really, really know what you are doing, you are just asking for trouble.
... and even if you still reckon you know enough, don't go alone.
Its not scouts.
I have "gone bush" with aboriginals that still lead reasonably traditional lifestyles, and even they need a bit of "help" these days to last more than a few days. Mind you, they do pretty well considering they have been exposed to our western ways ... and the buggers catch more fish with a spear than I did with $1000 worth of rod, reel and lures.
I have been subjected to sleep deprevation, restricted food and water, hazardous environments and just plain mind games on top of all that to try and break you. All of those things will affect how your mind and body operate (which is why they subjected me to them in the first place). You need to factor that into your planning because while it looks romantic on TV or sounds easy in a book, its tough, real tough out there.
This site has a lot of experienced campers but there is a huge gap between that and what you are talking about, you probably won't find the advice you want on here. An experienced camper can tell you how to make damper with just flour and a can of beer if you get stuck, but you will be digging in the ground to find your carbs and fibre.
A lot of us tow a small house around with us, armed with fridge/freezers, solar panels, 12 volt battery systems, water tanks, gas bottles, hot water systems etc etc. You on the other hand represent the "purist" who wants to do it the hard way, whilst here you can find a wealth of great information on how to do it the easy way.
I like that you have the guts to really test yourself, because doing what you want to do will really test you and you will learn a lot about yourself in the process and I think thats great. You will emerge from it knowing what the saying "what can't kill you only makes you stronger".
I would suggest any publication by the Australian army on survival, or really any Australian publication on survival, would be a good place to start. A few episodes of "The Bush Tucker Man" won't get you too far, although if I was ever stranded in the bush, that is who I want in my corner. I have met and drank with Les Hiddins, he is a really down to earth bloke, just like he is on TV and he really can do what you are thinking of doing.
Best regards to you, but remember, do the research and take a mate.
