I have always had, as I know many people have, a singular passion for Australia. I do love the sunburnt country, its ancient landscapes, its exhilarating reaches of sand and sea.

The forces that are in play on climate change essentially revolve around the generation of power, the transportation of goods and services and people, and the sorts of materials that we use to fuel the whole of our civilisation.

In particular, Australia, because of its ancient geography, soil profile and distinctive weather patterns, is more adversely affected by climate variability than some other continents.

There are a range of associated impacts related to increasing temperatures which affect both evaporation rates and river systems, which are already over stressed, and these will hit farming communities and the health of crop lands.

Once you start to look into the guts of climate change you find that just about every scientific institution in the world is conducting research on the issue.

That was the crossover line for us, to be able to play that many shows, sell them out real quick and have that tribe queue up outside and still be a mystery to everybody else.

In our early period we pretty much survived or perished on our capacity to reach people, and on getting into the pattern of having no money and playing lots of shows.
