It's been twenty years since the terror attacks of 9/11. We'll hear from people who were there, and who felt the aftermath. We'll also hear about how 9/11 changed the way we live our lives, and the built environments around us. Also in the programme, we'll hear about how language learning has boomed during lockdown, and how a refugee-led language programme is connecting people all around the world. We'll also hear about how protracted lockdowns are affecting Australians, and how one Aussie staple - Victoria Bitter beer - is encouraging its customers to get vaccinated.

All through the show we'll be joined by Peter Ryan, senior business correspondent at the ABC.
