Suncorp Group Limited is an Australian finance, insurance, and banking corporation based in Brisbane, Queensland, Australia. It is one of Australias largest banks (by combined lending and deposits) and its largest general insurance group, formed on 1 December 1996 by the merger of Suncorp, Metway Bank and the Queensland Industry Development Corporation (QIDC). Queensland established the State Accident Insurance Office in 1919, to provide mandatory injury compensation insurance to workers in the states business sector. New legislation soon after created a larger insurance body, the State Government Insurance Office (SGIO) which took over the State Accident Insurance Office. General insurance, third party and life products were added. SGIO later expanded into building society operations, superannuation, and finance. In 1960, new legislation establishing the SGIO as a separate corporation was passed, and the group became subject to state regulatory oversight. In 1971, the SGIO took another step toward full-fledged corporate status, forming its own board of directors. At this time, the operations involving injury compensation for workers were placed under a separate board. By 1976, as SGIOs insurance operations took on a more commercial orientation, the company closed down its building society operations.
