    19/1/2026 | 55 mins.
    DNA testing has helped family history researchers fill in the blanks in their family trees. While that can be a good thing, it can also lead to unexpected consequences.

    This event was recorded at the State Library of NSW for Family History Month 2025.

    We asked for workers and got people — life on the controversial visa putting food on your plate

    14/1/2026 | 54 mins.
    A workforce we rarely hear about, lives in limbo, and stories from the coalface. From economic gains and cultural exchanges to exploitation and absconding,  what are the successes and problems of the Pacific Australia Labour Mobility (PALM) scheme? Who picks and processes those yummy strawberries you're about to put in your shopping trolley, or the crisp veggies you might stir-fry tonight? Did you know it could be a nurse or a police officer from a Pacific Island or Timor Leste on a temporary seasonal visa?
