January 26, known officially as Australia Day, marks the beginning of the European colonisation of what would become known as Australia.

While the date is celebrated as Australia's national day, for Aboriginal and Torres Strait Islander people January 26 holds the significance of marking the beginning of the invasion and theft of their lands by colonisers, and for many indigenous people the day is marked as a day of mourning and resistance.

This week on Women on the Line we look at discussions surrounding changing the date of Australia's national day, and a recent decision by the City of Yarra Council in Melbourne to change the way they engage with January 26. We'll hear from Yarra Mayor Amanda Stone, and from Wurundjeri Elder Annette Xiberras.
