Almost 18 months after an ABC Four Corners investigation into the Northern Territory’s child detention system sparked national outrage, the Royal Commission will hand down its recommendations at the end of this week.

Footage of teenage inmate Dylan Voller hooded and strapped to a restraint chair in the Don Dale Detention Centre quickly garnered enough outrage to cause Prime Minister Malcolm Turnbull to announce the royal commission within 48 hours of the episode airing.

Since it was established, the commission has heard from more than 210 witnesses, had 12 weeks of public hearings and received more than 320 submissions from individuals, organisations and government.

Human Rights Law Centre senior lawyer Shahleena Musk says it is important that the government accept all recommendations handed down, but said the issue isn’t confined to just the Northern Territory.
