    Hi

    Not sure if this topic has been covered - if so, please just point me to the thread.

    Does anyone have any info, links, whatever - re predicted impact of climate change on various regions around Australia? For example, if looking at where to purchase land, where would be a safe bet for the future? Anywhere near Sydney (ie within a few hours drive)?

    That's a good question. I've seen estimated sea level rise from 3m to 70m, with everything in between. A fair amount of people seem to be focusing on a number of 7m(as per the UN). Since the description of weather patterns because of climate change is "erratic" and "extreme"(which pretty much means dry seasons will be drier and wet seasons will be wetter), you can't really plan for this since they aren't quantified. Luckily, permaculture earthworks will help with those extremes, if done right. So I'd focus on that 7m sea level rise since that would be a huge factor in where to locate, and something that you could plan around.

    Here are several links:

    These were passed along from Marko, so you can thank him!

    fiona,

    almost how long is a piece of string, be hard to make the determination you talk of until some factual evidence becomes available, i would look for at least an acre, of good as soil, high enough to be out of reach of flooding(so no flood plain land) close enough to a centre for your medical needs, once found build a simple house, and begin growing food, shortage of food will likely be the first thing to hit the collapsing cities, and hungry masses are not easy to live in the midst of. if you can afford it go stand alone solar and wind, and while fuel is reasonably available(another that has no factual evidence ass yet, and even if it is to stop flowing you won't be alone when caught out, so be self sustainable.

    we have example of house we built which came out at the time around 50%m cheaper than what was on offer and still on offer at more expensive price. this house too was built with tight budget, being old pensioners with excellent credit record did not count if we wanted to borrow extra. this house technically a 1.5 bedroom job 6mX9m gable roof(would liked to have simpler skillion) we can fit 2 grand kids in at a stretch.

    anyhow choose northern aspected land on 4 to 6% slope running down to the road the other way you get all road run off.

    Let us know if we can help you with any specific, pre-purchase/planning issues.

    Cheerio, Markos.

    Thanks for those links - they're very helpful. And I ended up following a few pathways to further info too.

    What I'm reading seems to be looking at sea level rises of amounts like 1-2 m over the next hundred years - and that being quite a lot. Is 7 m likely? Over what time period?

    Thanks again.

    It depends on whether we get runaway climate change or not. Once positive feedback loops kick in, things will happen faster and more unpredictably. Short answer, no-one really knows what is going to happen, or when.

    And from your macro-level reading to date, I'm sure you are already aware that sea level rise is not our most immediate concern. Even very small disruptions to the climate can have a huge effect on weather events. This ABC Catalyst report explains it very well, in laypersons terms:
