Why NSW Created the Government Insurance Office in 1926
Updated: Sep 27
The origins of GIO reveal a public debate about workers’ compensation, insurance costs and who should carry the consequences when someone is injured at work.
My grandfather died in a Bowenfels quarry in 1939. His death is one reason I began looking back at how Australia built systems to support people after workplace injury—and what those systems promised families like mine.
That research led me to the Government Insurance Office of New South Wales, or GIO. Its familiar name began in a period of intense disagreement about workers’ compensation.
A new compensation law
In the mid-1920s, the NSW Government set out to reform workers’ compensation. Its proposals required employers to insure against their compensation liability, widened the definition of a worker and increased benefits. They also introduced cover for certain diseases.
The reforms met strong opposition from insurers and employers’ organisations. According to a history published by the NSW Parliamentary Library, representatives of 71 insurance companies objected to the bill in June 1926. The next day, Premier Jack Lang announced that the government’s existing Treasury Insurance Branch would compete for workers’ compensation business as the Government Insurance Office.
The proposal had a practical purpose. Employers would need insurance under the new law; the government wanted them to have an option if private insurers charged too much or withdrew from the market.
The first days of GIO
The GIO began operating when the Workers’ Compensation Act commenced on 1 July 1926. The Parliamentary Library’s account describes applicants filling the temporary office and spilling into its corridors. It also records that the GIO offered a lower rate for the newly introduced disease cover than rates being discussed by private insurers.
Those details show the pressures surrounding the new scheme. Compensation depended on more than a law setting out entitlements. Employers needed access to insurance, and the price and availability of that insurance shaped how the system would work.
Parliament gave the office formal legislative authority through the Government Insurance (Enabling and Validating) Act 1927. The GIO later grew well beyond the workers’ compensation business for which it had first been established.
A longer history than one government
The GIO did not appear from nowhere. NSW had previously used government funds and insurance arrangements to cover some public risks. In 1917, the Treasurer’s Workmen’s Compensation Fund was established for government employees covered by the earlier compensation law.
Nor did the creation of GIO settle every question about compensation. The scheme changed repeatedly in the decades that followed. Benefits, premiums, eligibility and the relationship between public and private insurers remained subjects of debate.
GIO itself changed. It expanded into other forms of insurance, adopted the name GIO Australia in 1990 and was privatised following legislation passed in 1991. The public institution created during the 1926 dispute became part of a very different insurance landscape.
Why this history appears in Shattered
My grandfather died thirteen years after GIO began operating. Its creation did not mean that every injured worker or bereaved family received enough support. My family’s experience is part of why I wanted to understand the distance that can exist between a system’s purpose and a family’s life within it.
Episode 1 of Shattered, Origins of Control, follows the development of workers’ compensation from community support into law and administration. The birth of GIO is one chapter in that history. It shows people trying to answer a question that has endured for a century: when work causes harm, how do we ensure that workers and their families are supported?
The answer has never rested with an insurer alone. It involves employers, governments, health professionals and communities—and the choices they make after an injury occurs.
