    Advance Australia Fair? Is "trickle-down racism" damaging social cohesion?

    12/11/2026 | 54 mins.
    Australia's national anthem proclaims that: "for those who've come across the seas we've boundless plains to share". But with Australia's immigration program once again under the political spotlight, is that really true? How does what leaders say about refugees and migrants ripple out into the community, and what attitudes and behaviours does it give license to?
    Mariam Veiszadeh was born in Afghanistan and moved to Australia as a child. She's devoted her life's work to creating a fairer Australia for refugees and migrants. She explores what it might take to foster social cohesion and a sense of belonging in Australia, and to ensure that everyone gets a fair go.
    The 2026 Kaldor Centre Oration was recorded on 20 October 2026 at the Kaldor Centre for International Refugee Law in partnership with the Centre for Ideas at the University of New South Wales.

    11/11/2026 | 54 mins.
    Is the witch back?  The word, the craft, the movement, and as a viral social media phenomenon #witchtok? Did the witch ever really disappear? Women who don't conform or who challenge certain kinds of power have long been persecuted as witches. An eye-opening conversation about the past and present of witchy women.

So why are we reaching back to ancient myths for life lessons and a deeper understanding of the human condition?

    The meaning of loss — whether it devastates you or saves you

    05/11/2026 | 53 mins.
    When you lose people and places, you can't bear to be without - or the baggage that weighs you down, is loss really nothing more than change? This conversation goes looking for loss in all its shapes: the identity we misplace growing up between cultures, the self we lose and remake as our bodies change and the strange, unsettling experience of coming face to face with who we used to be.
