Workers’ compensation data
Key workers' compensation statistics are available on the statistics page. A more detailed analysis of workers’ compensation statistics can be found in the Australian Workers’ Compensation Statistics reports.
Limitations of workers’ compensation data
Workers’ compensation statistics do not capture all occurrences of work-related injuries and diseases for the reasons below:
- Only employees are eligible for workers’ compensation, which means self-employed workers are not included in workers’ compensation statistics. Around 10% of Australian workers are self-employed.
- Absences from work of less than one working week are excluded from the Australian Workers’ Compensation Statistics reports due to the different employer excesses that exist across Australia and the possibility that claims for injuries and diseases below these excess periods are not reported to workers’ compensation authorities.
- While the majority of employees are covered for workers’ compensation, under general Commonwealth, state and territory workers’ compensation legislation, some specific groups of workers are covered under separate legislation. Every effort has been made to compile data from all groups of employees, but it is currently known that claims lodged by police in Western Australia and military personnel within the defence forces are excluded.
- Diseases are significantly under-represented in workers’ compensation statistics. That is because many diseases result from long-term exposure to agents or have long latency periods, making the link between the work-related disease and the workplace difficult to establish.
An estimate of the proportion of work-related injuries that are claimed through workers’ compensation can be found at Comparison of compensation data with all incurred work-related injuries.
The reasons why some employees do not apply for compensation can be found at Factors affecting applications for workers’ compensation and in the report Work Related injuries in Australia: Who did and didn't receive workers compensation 2009-10.

Workers' Compensation: Classifications
National Data Set for Compensation-based Statistics (NDS)
The National Data Set for Compensation-based Statistics (NDS) is a standard set of data items, concepts and definitions for inclusion in workers’ compensation systems operating in Australia. The NDS has been implemented in workers’ compensation-based collections administered by state, territory and Australian government agencies to enable the production of national and nationally comparable workers’ compensation-based data.
- The National Data Set for Compensation-based Statistics (NDS), Third Edition, July 2004
- National Data Validation System (NDVS) Second Edition - Revision 1, June 2002
- The National Data Set for Compensation-based Statistics (NDS), Second Edition, May 1999
The first edition of the NDS (NDS1) was published in April 1987 but is not available electronically. The first data produced under this system relate to the 1991–92 reference period. The second edition of the NDS (NDS2) which includes changes to the scope and some of the definitions and classifications was published in May 1999 with the first year of reporting being the 2000–01 reference period. Due to the changes to the scope, the data between these series are not comparable. Some minor amendments were incorporated into this document in June 2002 National Data Validation System (NDVS) Second Edition - Revision 1, June 2002.
A major review of the NDS was undertaken in 2004 to include additional data items. The National Data Set for Compensation-based Statistic 3rd edition has been progressively implemented into the Australian workers’ compensation system since 1 July 2005.
Technical Manual for the National Data Set for Compensation-Based Statistics has also been developed to assist data suppliers.
Types of Occurrence Classification System
The Type of Occurrence Classification System (TOOCS) was developed for use in coding details of workers' compensation cases reported to workers' compensation agencies. Employers may also use the System for coding workplace injury and disease occurrences. Separate codes are available within TOOCS for recording the nature, bodily location, mechanism, breakdown agency and agency of the injury or disease involved in the incident.
- Type of Occurrence Classification System, Third Edition Revision 1 (3.1) May 2008
- Type of Occurrence Classification System, Third Edition (3), March 2004
- Type of Occurrence Classification System, Second Edition - Revision 1 (2.1) May 2002
- Type of Occurrence Classification System, Second Edition (2) - July 1999
The first edition of TOOCS was published in December 1990 (not available electronically). The type of Occurrence Classification System, Second Edition - July 1999coincided with the introduction of NDS2 to be used from 2000-01. This was subsequently revised with Type of Occurrence Classification System, Second Edition - Revision 1 (2.1) May 2002 introduced from the 2002-03 reference period.
The third edition of TOOCS (TOOCS3) was developed to align with the International Classification of Diseases – 10th Revision, Australian Modified version. This edition is associated with the introduction of NDS3. Similar to NDS3, TOOCS3 has been progressively implemented into the Australian workers’ compensation system since 1 July 2005.
Some minor amendments were then made in May 2008 with the release called TOOCS3.1. See TOOCS3.1 Manual Updates - Summary Document for details of these changes.
