You wouldn't be human if you hadn't from time to time wondered what the meaning of all of this is. Who am I? Is there a purpose? Why am I here? And how can I live a good life? Well of course you're not alone – some of history's biggest thinkers have been coming up with answers to these questions for thousands of years. So what can we learn from their conclusions?

Do you want to live in Putin’s vision of a world in which ‘the big boys’ dominate …. or in one in which smaller nations have a voice? If it’s the latter, so the President of the Czech Republic Petr Pavel, you need to support Ukraine. This war isn’t just about the borders in Ukraine or security in Europe, it affects the world and our principles of sovereignty, integrity, freedom, and the right of smaller nations to decide their own future. Hear from one of Europe’s foremost voices on global security on the implications of the war in Ukraine for the world.

A freckle-faced kid from Bondi, Pauline Menczer fought the entrenched sexism of the pro-surfing scene to became women's world surfing champion and pave the way...er, waves..for girl grommets today. But all the while she was also fighting another battle inside her own body’s cells. Ironwoman and surf lifesaving champion Bonnie Hancock became the fastest and youngest person, and the first Australian woman, to circumnavigate Australia on a small surf ski, solo. What possessed her to paddle 12,700 kilometres through crocodile and shark-populated waters, mega-waves, and worse? Pauline and Bonnie join Big Ideas' host Natasha Mitchell for a conversation that might inspire you to chase your dreams, big or small.

This event was organised and hosted by the Queenscliffe Literary Festival.

Australia's unique biodiversity, a product of almost 50 million years of glorious evolutionary isolation, is in freefall. The threats are not just the rabbits, the cane toads, the cats and foxes – the common culprits. Let's not forget the small but impactful smooth newt or the fierce red fire ants, and the many invasive weeds. Twenty new weeds will establish in the wild in Australia this year – and every year to come … unless things change. But is it possible to stop this ongoing invasion? How do we go about it?
