How Long Can NSW Police Detain You Without Charging You?

Law checked: 18 July 2026

This article gives general information about arrest and detention in New South Wales. It was checked on 18 July 2026 against Legal Aid NSW guidance and the current New South Wales legislation. Police powers depend on the facts, the particular statutory power being used and whether any special order, warrant or declared area applies.

Short answer

There is no single Australian rule allowing police to hold every person for a fixed period without charge. The permitted period depends on whether the person is under arrest, detained for investigation, held under protective or intoxication powers, subject to terrorism legislation, or held under another specific law. Legal Aid NSW guidance explains ordinary arrest and custody; the controlling time rules and extensions are in the current New South Wales legislation and related legislation.

Establish your status

Ask, “Am I under arrest?”, “What offence am I suspected of?”, “Am I free to leave?” and “When did the investigation period begin?” Ask to contact a lawyer and a support person. Rights to communication, interpreters and interview safeguards vary with age and circumstances and are summarised by Legal Aid NSW guidance.

Time can be excluded or extended

Some statutory investigation periods exclude reasonable time used for specified activities, and a court or authorised officer may be able to approve an extension. That is why a bare number can mislead. A lawyer should check the custody record and the exact legal basis under the current New South Wales legislation if detention appears prolonged.
