"It's all well and good to sound the fire alarm, but you've also got to show people where the exits are."

That's the philosophy behind Damon Gameau's latest film, Regenerating Australia.

It's the result of months of in-depth conversations with people across Australia, and imagines what the country could look like by the end of this decade, if a few key decisions were made.

As he tours the film, Gameau's hoping to provide communities with the tools that they need to get involved in creating that future.
