The ceremony concluded without any reference to the incident, and the royal couple proceeded to meet hundreds of people who had waited outside to greet them.
Australia is a Commonwealth country where the King serves as the head of state.
Thorpe, who is an independent senator from Victoria and an Aboriginal Australian woman, has long advocated for a treaty between Australia’s government and its first inhabitants.
Australia is the only ex-British colony without one, and many Aboriginal and Torres Strait Islander people emphasise that they never ceded their sovereignty or land to the Crown.
Afterwards, Thorpe told the she had wanted to send a “clear message” to the King.
“To be sovereign you have to be of the land,” she said. “He is not of this land.”
She said the King needed to instruct the Parliament to discuss a peace treaty with the first peoples.
“We can lead that, we can do that, we can be a better country – but we cannot bow to the coloniser, whose ancestors he spoke about in there are responsible for mass murder and mass genocide.”
Thorpe, who was wearing a traditional possum skin cloak, described the late Queen Elizabeth II as “colonising” when she was sworn in as a senator in 2022.
