King Charles III's landmark address to Australia's Parliament House on Monday was disrupted by a protesting lawmaker who shouted at Charles, "You are not my king."
Charles was finishing his address at the Great Hall of Parliament House when Sen. Lidia Thorpe, an Indigenous senator, approached the stage and began shouting, accusing British colonizers of taking Indigenous land in Australia.
"You committed genocide against our people," shouted Thorpe, an outspoken advocate for Indigenous rights. "Give us our land back. Give us what you stole from us -- our bones, our skulls, our babies, our people."
"You are not our king, you are not sovereign... You destroyed our land," she said.
The cameras and the crowd inside the Great Hall turned towards Thorpe as Charles and his wife Queen Camilla watched her outburst without any visible reaction.
Thorpe was eventually stopped from approaching Charles and was escorted out of the chamber.
Buckingham Palace has not commented on the incident, which came during one of Charles' most important engagements on his first official visit to Australia as monarch.
Charles and Camilla landed on Friday for a five-day tour of Australia, one of the 15 Commonwealth realms where Charles is sovereign. The tour is Charles' first visit to an overseas realm since he became king in 2022 following the death of his mother, Queen Elizabeth II.
When Charles was crowned in 2023, the new king faced protests in several Commonwealth countries, including Australia.
Some voices in Australia's indigenous communities, known as the country's First Nations people, have expressed apathy towards the coronation, pointing out that their land was stolen under the crown when British settlers first arrived in Australia.
At the time of the coronation, Australia's Republic Movement Co-chairman Craig Foster told ABC News that the moment marked, "an opportunity to think about our broader path forward and need for full and final independence."

During their visit to Australia, Charles and Camilla have taken time to attend a church service in Sydney and visit the Tomb of the Unknown Australian Soldier in Canberra.
A royal source told ABC News about their visit, "Their Majesties are deeply grateful to the very many thousands who turned out to support them, and are only sorry they didn't have a chance to stop and talk to every single one. The warmth and scale of the reception was truly awesome."
On Wednesday, Charles will travel to Samoa for the Commonwealth Heads of Government Meeting.
