Of Arrernte and Garrwa descent, Dujuan shared his story of nearly being imprisoned at the age of 10.
"I felt like a failure at school," he told the council. "I was always worried about being taken away from my family."
He said his run-ins with the police could have ended with him jail, but the intervention that saved him was re-acquainting himself with learning about his Aboriginal culture, identity, language.
"I want my school to be run by Aboriginal people. I want, in my future, to be able to learn strong culture and language," he added.
"I want adults to stop putting 10-year-old kids in jail."
'They found a way to keep me safe'
He attributes his wellbeing and positive outlook to the support of his family.
"I was lucky because my family, they know I am smart. They love me. They found a way to keep me safe," he told the council.
Speaking to SBS News, he said he was humbled by the applause in the chamber after his speech.
"People did listen when they heard my voice," he said, pausing as he recalled his family's reaction sitting in the chamber. "My grandmother told me she put in the ear plugs to listen to what I was saying."
He said he was motivated to travel to Geneva to share his story on the world stage to ensure Indigenous kids can have a future that does not include prison.
"Every day kids get taken from their families and they are not returned to them until they're [sometimes] eighty years old."
Dujuan said the threat of jail was a very real concern among Indigenous children in his community. Close to 100 per cent of the youths in jail in the Northern Territory are Indigenous Australians.
Nationally, nearly 600 children are detained in jails each year with Aboriginal and Torres Strait Islander kids over-represented.

Letter to PM
Dujuan has written to Prime Minister Scott Morrison inviting him to see the documentary featuring his story, In My Blood It Runs.
He is hoping that Mr Morrison watches the film and says he would like to sit down with the Prime Minister personally to share his story.
He has yet receive a response, but in the meantime is working with his grandmothers through the group Children's Ground to promote an Indigenous-education model.
"In Australia, almost every Aboriginal kid gets taught English. And in every other country, they teach kids another language and culture - except for Australia."
Never far from his mind is the story of the Don Dale youth detention centre in the Northern Territory, that was shut down following a 2017 Royal Commission into the territory's youth justice system.
Knowing how his life could have very nearly been very different, he said stopping the imprisonment of 10-year-olds in Australia is something he is passionate about.
"I want to see the juvenile justice age change from age 10 to 14."
Push for Indigenous-led education model
The In My Blood It Runs documentary will be in cinemas across Australia from February 2020.
