Australia is a wild continent with some of the most intense weather on the planet. From massive bushfires to severe cyclones and devastating flooding; extreme weather is becoming part of our everyday lives. How do we take what we’ve learned from our past to better prepare and adapt for our future?

On a scratchy recording made in a Melbourne hotel room, a man admits to committing murder. But as journalist Alicia Bridges investigates the man on the tape known as Mr Big, she finds herself in a world of lies and subterfuge, where very few things are as they seem. The recording leads her deep inside an international controversy, to a world of secrets that powerful institutions don't want revealed.

Mr Big is the latest season of Unravel, the ABC's award-winning true crime podcast.
