The Member for Lingiari, Marion Scrymgour, became the first Aboriginal person to preside over Australia's House of Representatives from the Speaker's Chair on Monday.
Writing social media, the MP said: "Today I was the first Aboriginal person to sit in the Speaker's Chair in the House of Representatives as a member of the Speaker's Panel."
"It was a huge moment for the Parliament, but more importantly, it was a message to young Aboriginal people back home in the NT," she said.
"Aboriginal people deserve to be in every chair, at every table.
"I grew up one of 11 siblings from a working class family in Darwin. My father was a Stolen Generations man who was forcibly removed from his family by the Parliament I sit in today.
"Change happens, it can be slow and it can be painful, but Aboriginal people are strong, we deserve to take our place in this country."
The usual Speaker, Milton Dick MP, noted the occasion, congratulating Ms Scrymgour and describing it as "an incredible honour for the Australian Parliament".
Ms Scrymgour has held the NT federal seat of Lingiari since 2022, having been re-elected earlier this year.
For 11 years she served as the Member for Arafura in the Northern Territory Legislative Assembly, from 2001 to 2012. During this time, she held the senior roles of Minister for Child Protection, Minister for Natural Resources, Education, and Deputy Chief Minister.
