The first Warwick Show was held on 12th September 1867 and was run by the Eastern Downs Horticultural and Agricultural Association.  The object of the committee was to promote the development of agricultural, pastoral, horticultural, mineral and industrial resources of the District.  For this purpose, it was proposed to hold a Show in Warwick each year for the display of all types of livestock, agricultural produce of all kinds, wool, minerals and machinery, together with such objects of manufacture, produce or the arts, as may seem desirable.

 On 29 November 1962 the Eastern Downs Horticultural and Agricultural Association became the Warwick Show and Rodeo Society Inc.  The Society is controlled by a Management Committee of fourteen elected members.  There are one hundred and eighty (180) life members and six hundred (600) family and single members of the Warwick Show and Rodeo Society.  It is the duty of the Management Committee to handle the affairs of the Society and make decisions relating to the running of the Show each year.  The Management Committee is assisted by a Show Committee made up of a Show Chairman and other interested parties. 

Up to 1982 the showgrounds was a total of twenty-three (23) acres.  In 1982, to accommodate the growth of the Show, a further sixteen (16) acres was bought.  Today the Society also has a lease on five (5) acres of land on the eastern side of the showgrounds, this being the only area available adjacent to the showgrounds.  As the Warwick Show has grown, there has been a need to reorganise the grounds to allow room for expansion of sections.  This has meant that some sections have had to operate on alternate days so the same area could be utilised by more than one section.
