'Thomas' - not his real name - was 13 years old when he began his first stint in prison.
Following the sudden death of his father, he had robbed a shop in Australia’s Northern Territory (NT). He was detained for a week but, within a month, he was back in custody for another burglary.
Five years on, the Aboriginal teenager has spent far more of that time inside prison than out.
“It’s hard changing,” Thomas tells me. “[Breaking the law] is something that you grow up your whole life doing - it’s hard to [stop] the habit.”
His story - a revolving door of crime, arrest and release - is not an isolated one in the Northern Territory.
For many, over the years the crimes get more serious, the sentences longer and the time spent between prison spells ever briefer.
The Northern Territory is the part of Australia with the highest rate of incarceration: more than 1,100 per 100,000 people are behind bars, which is greater than five times the national average.
It’s also more than twice the rate of the US, which is the country with the highest number of people behind bars.
But the issue of jailing children in particular has been thrust into the spotlight here, after the territory's new government controversially lowered the age of criminal responsibility from 12 back to 10.
The move, which defies a UN recommendation, means potentially locking up even more young people.
