​​​​​Functions of the Water Efficiency Labelling and Standards (WELS) scheme are detailed in Commonwealth, state and territory legislation.

Legislation sets the goals and regulatory functions of the scheme, including our powers to monitor and enforce scheme requirements.

This includes our powers to enforce the requirements of water efficiency standards.

Commonwealth legislation

There are two Commonwealth Acts, and associated legislation, that provide the legal framework for the WELS scheme.

Refer to the legislative documents for full details of all powers and functions they establish. This overview should be used as a guide only.

The key piece of legislation is the Water Efficiency Labelling and Standards Act 2005 (WELS Act),​ which establishes the:

  • objects of the Act
  • definition of the term ‘supply’ in relation to the WELS scheme
  • authority for the Minister to establish registration processes and determine what products are regulated by the scheme
  • WELS Regulator and their functions and powers
  • offences and civil penalties relating to the WELS scheme
  • appointment of WELS inspectors and their powers, including information they can require from entities
  • WELS special account and its allowable uses
  • decisions that are ‘reviewable decisions’.

  • Water Efficiency Labelling and Standards Regulations 2005 which establishes
    • additional detail on who can register products
    • procedures for infringement notices, including for payment extensions and withdrawal of notices

    • additional details of registration processes and requirements, including periods of registration, and requirements for a product to remain registered
    • instances when a registration can be cancelled or suspended
    • the requirement that the WELS Regulator keep a register of WELS products (our product registration database).
