Two decisions, on the same charge, about the same young person, made days apart:

• Police bail, at the station, within hours, by an officer, without review.
• Court bail, after transport, a first appearance and a hearing, by a magistrate, with representation.

They disagree 60 per cent of the time, and the disagreement always runs the same way — toward release.

That is a systematic gap between two decision points, not noise. If the second decision-maker reverses the first in three cases out of five, either the first is applying a different standard, or the first is operating without something the second has. Both are true: the officer decides at 2am with no accommodation option to offer, and the magistrate decides after three days of somebody looking for a bed.

The jurisdictional spread makes the point unanswerable. Fifteen per cent of remand periods ended in bail in the Northern Territory; 84 per cent in Western Australia. The children are not five times more dangerous in Darwin. The difference is in the law, the practice and the available alternatives — which is to say, in things governments choose.

Filed as an idea, because the obvious fix has a bad history. The instinctive move is a statutory limit: no young person held on remand beyond N days without a substantive review. That is coherent, it matches how Australian law treats every other short-term deprivation of liberty, and it would bite hardest exactly where the numbers are worst.

It also runs directly into the current direction of travel. Several jurisdictions have recently moved the other way: the Northern Territory lowered the age of criminal responsibility back to 10 after raising it, Queensland has legislated tougher sentencing and is trialling electronic monitoring as a youth bail condition to April 2026, and Victoria scaled back its own commitment on the age. A proposal to cap remand is not a technical reform in that environment, and this site should not present it as one.

What is defensible now is narrower and follows from the same data:

1. A mandatory bail review within a fixed short period, on the papers if necessary, so that the five days do not depend on a listing.
2. Give the first decision-maker what the second one has. Most of the reversal is explained by an option that appeared in the interval. That is A bed shortage is being recorded as a judicial decision about risk.
3. Publish the reversal rate by jurisdiction and by cohort, alongside the caution rate. It is the cleanest available measure of whether a bail system is working, and it is already collected.
