Extended supervision and continuing detention orders.
For a small group of serious offenders, the sentence is not the end of the state's control. Under the Crimes (High Risk Offenders) Act 2006 (NSW), a court can order that a person be supervised in the community, or kept in detention, after their sentence has expired. This note explains the two orders, the test the court applies, and how these applications are contested.

What are these orders?
There are two orders. An extended supervision order keeps a person under supervision and conditions in the community after their sentence ends. A continuing detention order keeps a person in custody after their sentence ends. Both are made by the Supreme Court on application by the State.
The orders apply only to defined high-risk sex offenders and high-risk violent offenders who have served a sentence for a qualifying offence. They are not punishment for the original offence, which has already been served. They are directed at future risk.
The unacceptable risk test
The Supreme Court can make an order only where it is satisfied to a high degree of probability that the person poses an unacceptable risk of committing a further serious offence if not kept under supervision or in detention. That is a demanding test, and the onus is on the State.
Detention is the more serious order and is reserved for cases where supervision in the community would not adequately manage the risk. The court prefers the least restrictive order that will meet the risk.
How is risk assessed?
Risk is assessed with expert evidence, usually from psychiatrists and psychologists, using structured assessment tools and a close look at the person's history, treatment, and circumstances. The court weighs that evidence rather than acting on impression.
The quality of the expert evidence is often decisive. Both sides call experts, and the court has to be satisfied of an unacceptable risk to the high standard the Act requires before it will act.
The conditions of a supervision order
An extended supervision order can carry strict conditions: electronic monitoring, curfews, restrictions on where the person can live and work, limits on contact and movement, and requirements to attend treatment. The conditions can be onerous and are tailored to the risk identified.
Breach of a condition of a supervision order is a criminal offence in its own right, so a person under an order remains at risk of fresh charges if they do not comply. The conditions are enforced closely.
How are these applications contested?
Because the orders reach beyond the sentence, they are contested carefully. The defence tests the State's expert evidence, puts on its own, and argues about whether the risk reaches the statutory threshold and, if it does, whether supervision rather than detention is enough to manage it.
These are specialised proceedings with serious consequences for liberty. A person facing an application should have advice from lawyers who understand the Act and the assessment evidence. Our note on the non-parole period explains the sentence stage that precedes them.
Frequently asked.
What is an extended supervision order?
An order under the Crimes (High Risk Offenders) Act 2006 (NSW) keeping a high-risk sex or violent offender under supervision and conditions in the community after their sentence has ended. It is made by the Supreme Court on the State's application.
What is a continuing detention order?
An order keeping a high-risk offender in custody after their sentence has ended. It is the more serious of the two orders and is reserved for cases where community supervision would not adequately manage the risk.
What test does the court apply?
The court must be satisfied to a high degree of probability that the person poses an unacceptable risk of committing a further serious offence if not kept under supervision or in detention. The onus is on the State.
Are these orders punishment?
No. The original sentence has already been served. The orders are directed at managing future risk, not at punishing the earlier offence, though they can significantly restrict a person's liberty.
What happens if a supervision order is breached?
Breaching a condition of an extended supervision order is a criminal offence in its own right. A person under an order who does not comply can face fresh charges.
