Law checked: 18 July 2026
This article gives general information about arrest and detention in Victoria. It was checked on 18 July 2026 against Victoria Legal Aid guidance and the current Victoria 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. Victoria Legal Aid guidance explains ordinary arrest and custody; the controlling time rules and extensions are in the current Victoria 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 Victoria Legal Aid 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 Victoria legislation if detention appears prolonged.
