Police Arrest Powers - Perth, Western Australia

Public Safety Western Australia 3 Minutes Read · published February 11, 2026 Flag of Western Australia

In Perth, Western Australia, police arrest powers are exercised under state law and operational policies; local councils do not create separate arrest powers. This guide explains how arrest powers are used in Perth, who enforces them, what sanctions and reviews apply, and practical steps if you are stopped or arrested. It is written for residents and visitors who need clear, actionable information about rights, complaints and follow-up options in Perth.

You may ask the officer for the reason for your arrest and for their name or station.

Penalties & Enforcement

Arrest itself is a power to detain a person for suspected offending or to preserve public safety; penalties for conduct arise from the criminal offence charged and are set under Western Australian criminal statutes, not municipal bylaws. The City of Perth does not set fines or prison terms for state criminal offences. Specific monetary penalties and sentence ranges for offences are established in state legislation and sentencing law.

Where the council enforces local bylaws, breaches of those bylaws may attract fines or infringement notices issued by ranger or by-law officers, but the act of arrest for criminal offences is carried out by the Western Australia Police Force.

  • Enforcer: Western Australia Police Force for criminal arrest powers; City of Perth Rangers/By-law Enforcement for local bylaw compliance.
  • Complaints/inspections: contact WA Police for conduct in arrests, or City of Perth for bylaw enforcement concerns.
  • Appeals/reviews: criminal court process and disciplinary reviews for officers; time limits depend on charge and court rules and are not specified on the City of Perth pages.
Penalties for the offence leading to arrest are set by state law and are not listed on municipal bylaw pages.

Applications & Forms

No single City of Perth form governs police arrest powers. For complaints about police conduct, follow WA Police official complaint procedures or contact the WA Ombudsman where appropriate. For bylaw infringements, the City publishes infringement and appeal forms on its website or provides directions to pay or contest notices.

Common violations and typical outcomes

  • Assault or public order offences – may result in arrest, charge, and prosecution under state criminal law.
  • Driving offences (e.g., DUI) – arrest powers and suspension processes are governed by state road and criminal laws.
  • Breaches of City bylaws (e.g., local parking, pets) – infringement notices, not arrests by council, though serious conduct may involve police.

Action steps

  • If stopped, calmly ask why you are being detained and request officer details.
  • If arrested, request a lawyer and do not volunteer unnecessary information.
  • To dispute a bylaw infringement, use the City of Perth appeals process on the council website.
