Insurers are integral to the workers’ compensation system in Western Australia. They assess claims made by workers, and indemnify employers against compensation for accepted claims.

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 your requirements, and contains the full list of approved insurers and available resources.

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

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 insurers and service providers in the treatment of injured workers.

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

All insurers are required to issue workers’ compensation policies in an approved form. WorkCover WA has issued a Standard Employer Indemnity Policy (PDF – 70kb) which is the basis of all workers’ compensation policies.

The Checklist for Memoranda of Agreement and 92f Deeds (available on the Legal practitioners page) contains points to consider when completing and lodging these documents. Observing these points prior to lodgement will assist in ensuring these documents are processed and registered in a timely manner.

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

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 Program, further projects will extend functionality.

WorkCover WA Online facilitates several services. These include:

WorkCover Number (WCN) – requests

Insurers can request a new WCN and also search the WorkCover WA database for existing WCNs. Draft requests can be saved without submission, enabling required information to be progressively added.

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 through this application.

Submit WC12

The Form WC12 is supplied in Excel format via WorkCover WA Online and assists with the transition to the PRC 06 Premium Rates. The WC12 contains premium and claim information at the individual policy level showing both PRC 93 and PRC 06.

The industry based premium rating system for workers’ compensation insurance in Western Australia is based on the Australian and New Zealand Standard Industrial Classification (ANZSIC). The guide to completing the Form WC12 is available on the WorkCover WA website under Guidelines and forms.


Insurers can search for notified claims, view recent liability notices – Section 57(a) 3(c) – and submit new liability notices.

Policy cancellation

Policy cancellation requests can be submitted and recently submitted cancellation requests can also be retrieved.

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 2018.

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).

In 2012 WorkCover WA commenced the review of acts of terrorism legislation with a view to addressing identified anomalies and establishing a permanent, contemporary legislative arrangement for workers’ compensation liabilities arising out of acts of terrorism.

The review was finalised in 2013 and the recommendations of the review will be incorporated into the broader review of the Workers’ Compensation and Injury Management Act 1981.
