Perth Coastal Bylaw Guide - Sea Level Rise

Environmental Protection Western Australia 3 Minutes Read ยท published February 11, 2026 Flag of Western Australia

Introduction

Perth, Western Australia sits beside a dynamic coastline and owners of coastal property must navigate both local council bylaws and state coastal-planning guidance when assessing sea level rise risk. Local government development rules, building approvals and shoreline management measures interact with state guidance on coastal hazards, so early contact with your council and a formal coastal hazard risk assessment are essential.

Contact your local council early to confirm which local plan and approvals apply to your property.

Understanding the legal framework

Coastal adaptation decisions in the Perth metropolitan area are driven by a mix of local planning schemes, council local laws and state coastal policy and guidance. The Department of Planning, Lands and Heritage publishes state guidance on coastal hazard risk management and adaptation planning that councils reference when requiring coastal risk assessments and development conditions[1].

Penalties & Enforcement

Enforcement authority for unlawful works, failure to obtain required approvals, or breaches of conditions is usually the local council (via its Planning or By-law Enforcement teams) and, where relevant, the State through planning compliance processes. Specific monetary penalties for coastal development breaches are typically set in local laws or state legislation; where those figures are not published on the official guidance page they are noted below as not specified.

  • Fine amounts: not specified on the cited page.
  • Escalation: information on first, repeat or continuing offence amounts not specified on the cited page.
  • Non-monetary sanctions: councils may issue orders to remove unauthorised structures, require remediation, or lodge notices to comply; state planning authorities can refuse or condition approvals.
  • Enforcer and inspection: local Council Planning/Compliance officers and By-law Enforcement teams; complaints and inspections are handled by the relevant council department. See Help and Support for council contact links.
  • Appeals/reviews: appeals from local decisions commonly go to the State Administrative Tribunal or through the council review processes; specific statutory time limits depend on the instrument and are not specified on the cited state guidance page.
  • Defences/discretion: permits, development approvals, lawful-use certificates and documented CHRMAPs or coastal adaptation plans can form valid defences or provide discretion for approvals.
Always confirm penalty figures and appeal time limits directly with the enforcing council or tribunal.

Applications & Forms

Councils generally require a development application or permit for coastal works and may require a Coastal Hazard Risk Management and Adaptation Plan (CHRMAP) or hazard assessment prepared by qualified coastal/water engineers. Specific form names, fees and lodgement methods vary by council; the state guideline explains when councils can require a CHRMAP[1]. If a council publishes a dedicated coastal or development application form, submit via the council's planning portal or in person as directed.

Common violations and typical outcomes

  • Unauthorised shoreline works or seawalls โ€” likely enforcement notices and requirement to apply for retrospective approval.
  • Failure to lodge required hazard assessments โ€” application refusal or conditions imposed.
  • Non-compliance with development conditions โ€” fines or remediation orders (amounts not specified on the cited page).

Action steps for coastal property owners

  • Step 1: Contact your local council planning department to confirm applicable local planning scheme and any coastal policies.
  • Step 2: Commission a coastal hazard assessment or CHRMAP if required, using qualified engineers.
  • Step 3: Lodge a development application with all required reports and pay any application fee as set by the council.
  • Step 4: If refused or served with an enforcement notice, seek review via council processes or apply to the State Administrative Tribunal within the statutory time limit noted in the notice.
