Individual employers who meet the criteria to manage the workers’ compensation of their own employees are known as ‘exempt’ or ‘self-insurers’.

Self-insurers have a range of administrative requirements to perform when processing claims made by workers. Your performance against these requirements is actively monitored by WorkCover WA.

This section outlines the role and requirements of self-insurers, and contains the full list of approved self-insurers and available resources.

Approval and review of self-insurers


The Governor, on the recommendation of the Minister for Commerce, may exempt employers or groups of employers from the requirement to have a conventional workers’ compensation policy.

Self-insurers must:

  1. Have sufficient material and financial resources in WA to fulfil obligations under the Act.
  2. Provide to the WorkCover Western Australia Authority security in the form of a financial undertaking of 150 percent of the central estimate of outstanding claims liability, or $2M, whichever is the greatest.

Compliance Monitoring

WorkCover WA conducts annual reviews of all exemptions, to ensure satisfactory performance and compliance with legislative requirements. An audit based monitoring framework includes periodic audits and self-audits.

Performance Monitoring

To evaluate the performance of approved self-insurers, WorkCover WA has developed the Insurer and Self-insurer Principles and Standards of Practice.

Client Services

A self-insurer’s claims management practices should align with the requirements of the Act and provide a fair, equitable and effective service to injured workers.

Injury Management

To maintain continuing approval self-insurers must have an Injury Management Policy and Procedure document which demonstrates an organisation’s commitment to injury management and return to work.

Internal Dispute Resolution Procedure (IDRP)

All self-insurers are required to have a documented, accessible IDRP which is designed to resolve disputes internally.

Cancellation of Approval

A self-insurer’s exempt employer status may be cancelled if they do not continue to meet legislative requirements. Employers or group of employers that cease to be exempt are required to obtain a conventional policy of insurance.

Clinical Framework

WorkCover WA endorses the use of the Clinical Framework for the Delivery of Health Services by WA medical and allied health practitioners.

Self-insurers have a key role in monitoring and making decisions about injury management services. We encourage use of the Clinical Framework to inform collaboration between self-insurers and service providers in the treatment of injured workers.

See the Clinical Framework section to view the PDF and associated information.

Claims Managers Capability Framework

The Claims Managers Capability Framework sets out the practices, skills and behaviours expected of claims managers in the Western Australia workers’ compensation scheme.

The Capability Framework translates the Insurer and Self-insurer Principles and Standards of Practice into observable practices and behaviours which claims managers should demonstrate when delivering scheme services.

Data specification

The data requirements set out in the Insurer/Self-Insurer Electronic Data Specification arise from WorkCover WA’s obligations to monitor and recommend changes to the Western Australian workers’ compensation scheme, to promote employment safety and injury management, and to collect data that complies with the National Data Set specification.

WorkCover WA recently collaborated with the Insurance Council of Australia and workers’ compensation regulators in Tasmania, the Australian Capital Territory and the Northern Territory to develop the new National Insurer Data Specification (NIDS), a common specification for workers’ compensation data supplied by insurers and self-insurers. NIDS is closely based on the existing Western Australian specification but also includes data items specific to the individual jurisdictions while allowing for a common data extraction and supply process for insurers and self-insurers.

The implementation of NIDS in Western Australia commenced in January 2014.

Insurer/Self-insurer Electronic Data Specification

The Q2 Data Specification is available on the Insurer page.

WorkCover WA Online

Digital First is a multi-year ‘umbrella’ initiative adopted to coordinate a range of technology and business related projects that will see WorkCover WA transform a greater proportion of its business to an online or digital environment.

The initial projects focused on the establishment of the WorkCover WA Online platform and the transition from Insurer Online. Under the Digital First Platform, further projects will extend functionality.

WorkCover WA Online facilitates several services. These include:

National Insurer Data Specification (NIDS) – file submissions

Upload file submissions to WorkCover WA and also search submission history. Issues raised from submitted data files can be addressed and summarised. Conversations with WorkCover WA Scheme Information staff can be initiated and responded to.

Insurance cover for acts of terrorism
WA workers’ compensation acts of terrorism legislation (the legislation) is comprised of:

  • Workers’ Compensation and Injury Management (Acts of Terrorism) Act 2001 (the Terrorism Act), and;
  • Workers’ Compensation and Injury Management (Acts of Terrorism) (Final Day) Regulations 2002 (the Regulations).

The legislation was developed as an urgent response to the insurance industry’s sudden withdrawal of terrorism insurance products following the terrorist attacks in the United States of America on September 11, 2001.

If this arrangement had not been made, employers would have been without cover for claims arising  from terrorist events, and insurers would be in breach of section 160(3) of the Workers’ Compensation and Injury Management Act 1981 (WCIM Act) which requires insurers to insure an employer for the full extent of their liability.

The Terrorism Act was enacted as an interim arrangement pending the development of a national insurance scheme covering terrorism related workers’ compensation claims.

The Commonwealth Government has since developed a national scheme however it excludes workers’ compensation liabilities, which remain the responsibility of the States and Territories.

As it was not intended to operate indefinitely the Terrorism Act contains a sunset clause which has been extended several times (via the Final Day regulations), most recently to 31 December 2026.

Scheme features
The Terrorism Act provides for a post-event insurance arrangement where workers’ compensation liabilities resulting from an act of terrorism are capped with claims costs pooled and then shared by insurers and self-insurers.  The key features of the scheme are as follows:

Approved insurers and self-insurers to be excluded from their liability under section 160 of the WCIM Act to insure employers for workers’ compensation against a terrorist event providing that they hold a valid contribution agreement with WorkCover WA.

A $25 million collective liability cap for insurers and self-insurers with a reduction factor to apply for liability exceeding this cap (statutory benefits only, common law is excluded).

A 90 day time limit for claims applicable from the date specified in a Ministerial declaration. If no Ministerial declaration is made, injured workers may still be compensated providing that WorkCover WA is satisfied an act of terrorism has occurred – no time limit applies in this situation.

Liabilities to initially be paid from the Employers’ Indemnity Supplementation Fund (Supplementation Fund) and recovered from insurers and self-insurers.

Once liability is determined, insurers are collectively liable for 95 per cent (apportioned individually by market share). Self-insurers are liable for the remaining 5 per cent (apportioned individually by level of declared wages).
