To mark The Australia Institute's 30 years of big ideas, we have asked some of our good friends and leading thinkers from Australia and around the world to share a big idea for a better Australia.

The Australia Institute has spent the last 30 years producing research that matters, and this anthology offers fresh thinking about climate action, how to safeguard our democracy, the importance of bravery in policymaking, and how to address some of the biggest issues of our day: from gender-based discrimination to the housing crisis; from our relationship with the United States to keeping cities cooler.

In our first 30 years, The Australia Institute has shown how to make the impossible feel inevitable, and the radical seem reasonable. The works in this inspiring volume serve as a reminder that the solutions are there; Australia just needs the courage to implement them.
