A senator has heckled the King in Australia's parliament, shouting: "This is not your land. You are not my King".
Lidia Thorpe, wearing traditional clothing, strode up the aisle yelling: "Give us our land back. Give us what you stole from us! Our bones, our skulls, our babies, our people.
"You destroyed our land. Give us a treaty!"
She added: "You are not our King, you are not sovereign... you have committed genocide against our people."
Security stopped her getting close to the monarch and ushered the politician out the chamber.
Ms Thorpe is the first Aboriginal woman from the state of Victoria to become a senator. When she was sworn in she refused to take an oath of allegiance to the late Queen.
She was also one of about 20 people protesting as the royals laid a wreath at a war memorial earlier in the day.
Her outburst came after the King spoke to politicians and dignitaries at Parliament House in Canberra.
An indigenous leader, who welcomed the royals to Australia's capital on Monday, also called on him to apologise for colonial wrongs.
Aunty Serena Williams from the Ngunnawal people, performed a "Welcome to Country" and smoking ceremony.
She said: "We all have roles and responsibilities, and I have roles and responsibilities to my people. And I think an apology would be beautiful."
When asked if that meant the King himself should say sorry, she replied: "Yes. Because we have to acknowledge our past."

During his address in parliament, the King referenced the ceremony by Aunty Serena Williams.
He said he "deeply" appreciated the gesture, which he said offered the chance to, "to pay my respects to the traditional owners of the land on which we meet".
"In my many visits to Australia I witnessed the courage and hope that have guided the nation's long and sometimes difficult journey towards reconciliation," the King said.
However he stopped short of the apology indigenous leaders had hoped to hear.
