Compliance and Enforcement Policy

The Department of Water and Environmental Regulation (the Department) works to protect and manage Western Australia’s water resources and environment to support a healthy community, a strong economy and a sustainable future.
Last updated:

As part of its role in supporting the Ministers for Water and the Environment, the Department administers a range of related legislation. In doing so, the Department has significant statutory and regulatory responsibilities to deliver improved outcomes for public health, the environment and water resources.

The Department’s Compliance and Enforcement Policy was first published in 2021. The policy was updated in 2026 following a five-year review, which included consultation with stakeholders, to clarify the Department’s risk-based, proportionate and transparent approach to compliance and enforcement.

Compliance with the law is mandatory and the Department uses a range of regulatory tools to promote, monitor and enforce compliance. We aim to achieve a balanced approach that protects environmental values, while enabling responsible development and economic growth. We are committed to being a fair, consistent and effective regulator.

The Department’s Compliance and Enforcement Policy outlines how we:

  • encourage and support compliance
  • assess and respond to non-compliance
  • apply enforcement actions that are proportionate, consistent and risk-based
  • deter unlawful behaviour and address environmental harm.
