Recently though, our State Governments have discussed instigating a carbon trading scheme - the details are still to be decided - and that's an encouraging sign.

I guess for me what is more significant than success is the nature of each of the songs and of the words.

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.

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.
