I would suggest that you read The Final Energy Crisis - edited by Andrew McKillop. It is suggested that Australia will be one of the worst places effected by petroleum shortages. In fact if I remember it was stated that Australia would find it difficult to sustain 1/10 of its current population, where as France could sustain at least 1/2. You have problems in Australia with the poor quality top soils (that need to be pumped full of fertilizers to be productive), the reducing water table that needs petroleum to pump water out and the huge distances.My plan is basically to emigrate to southern Australia in 2010-2012 and take it from there. I think Europe's a complete death-trap in the long term, Britain especially. It's just so overpopulated; so reliant on the exporters. If any serious climate change were to happen, it'd also be the worst affected! Maybe I'm not an optimist for Britain haha!
If I were planning to move (which I am not) I think I would chose the southern counties of Ireland.
