AGA, and its predecessor organisations, date back to 1925 when the National Gas Association (NGA) was formed and the first gas appliance codes were written by the NGA. In 1962, the NGA and the Australian Gas Institute merged to form the Australian Gas Association (AGA). The AGA is a highly regarded not-for-profit association recognised nationally and internationally for its primary safety mission.
Since 1962, AGA has been involved in the development and continuous improvement of its services, simultaneously playing a key role in assisting the gas and related industries develop highly regarded safety standards for testing and certifying domestic, commercial and industrial appliances, components and other ancillary equipment.
Safety motivated projects such as the AGA Listed Gas Fitter Scheme exists to promote consumer safety and the need for regular gas appliance servicing.
