Watch Finding the Archibald

It's the biggest day in the centenary of the Archibald: Natalie opens her Archie 100 exhibition, the judges announce the winner of the 2021 Archibald and Rachel makes her big reveal - she's found her Archibald.

Rachel meets female artists, sitters and curators, and has her portrait painted for the 2021 prize. Meanwhile, Natalie's still searching for artworks for her show, including a 1980s epic of Molly Meldrum.

Rachel Griffiths embarks on her hunt through 100 years of Archibald history to find one portrait that captures the changing face of the nation while curator Natalie Wilson begins her quest to find 100 portraits for the Art Gallery of NSW's centenary exhibition.
