The same child, two prices

These are the government's own numbers.

Every state runs two responses to a child in trouble: a bed in a detention centre, or supervision in their community. The Productivity Commission publishes what each costs, every year, per child, per day. Set them side by side and they read like receipts.

National avg / day$3,634.90

Invoice B · one day on community supervision

Reading these numbers fairly

These are the government's own per-day costs for its own two responses to the same child. They are not the cost of any community organisation's program, and detention and supervision are not interchangeable for every child on every order. What the gap shows is the price of the system's default, not a menu.

3,358 children · $520m

on community supervision, for less than half the money

Where invoice A is paid

Eighteen operating facilities. Community programs work within reach of nearly all of them.

Each facility below is a door: it opens to the map of verified community organisations working nearby. Within reach does not mean substitute; it means the alternative exists and is fundable.
