As I mentioned on Rob Day's blog, Australia has fantastic solar resources, and the political climate has changed dramatically to be more embracing of renewable and low-carbon technology. Australia is racing towards an emission trading scheme by 2010. However, the preponderance of coal-fired power plants provides an additional opportunity for solar thermal technology. By augmenting the power production of coal-fired power plants (of which Australia has many), solar thermal technology can lower the carbon footprint of these plants in an extremely economical way.
One particular solar thermal company which found its origins in Australia has raised a $60m Series C round. It's worth checking out.
