Are you sure you want to use soil etc? The way I know you Ozzies you can handle some physical labour no problem, but lugging soil around does get a tad tedious. I'd suggest not making my mistake and really calculate EXACTLY how much soil you are talking about before going for it... I sure as hell made myself a lot of work. Cleanup also took ages longer...
That aside, what I always suggest to people interested in organic growing is doing a very basic little Permaculture course, or finding a nursery that specialises in it. Permaculture has a high focus on the soil's eco-system, and methods are easy and take little labour. Sure there are products that work fine, but it really is soooo easy doing it yourself that spending on some other bloke makes little sense once you do it.
Ozzies and Kiwis are really super fucking clued up in the field man, you guys have got a great culture of organic growing. I know because us Saffas come and take yer farm jobs 'cuz we work CHEAP
Tons of mates have come back from Oz with incredible photos and stories, and knowledge to boot!! Bet you'll find even better stuff out there than in Europe...
