brolga, which represents the native population and it is the state's official bird. Industrial influence The symbols on the shield are representations of Queensland's most abundant industries. The wheat industry's origins belong with the first settlers in 1788, as the farms were worked by the convicts brought over from England, an idea of Governor Phillip. During the years till 1795, the wheat industry slowly gained popularity and by the late 19th century was a strong force in the agricultural industry of the state. The sugar industry became established by 1868 in Mackay which was a mere four years after the first commercial sugar mill was opened in Cleveland, south of Brisbane. Sugar and Coffee regulations were brought in by Parliament later that year as the industry spread rapidly and with the creation of the Mackay Central Sugar Mill Manufacturing Company ten years later in 1878, the sugar industry had reached its colonial peak.

The mining industry began with the discovery of copper on 20 May 1867 by Ernest Henry in Cloncurry and the industry climbed with the Gold Rush which occurred on 3 September 1873 when gold was discovered in Georgetown. The beef industry was quite prevalent by the late 1880s and by 1890, Queensland had exported Australia's first major export overseas which consisted of 1500 tons and by the 20th century that number had exploded to 43000 tons. Supporting animals As for the supporting animals, the brolga is Australia's only native crane and is described as "more than a metre tall and their outstretched wings can measure two metres across. The adults are mainly grey and have a long thin neck, a bare head and a patch of striking red coloured skin on the lower part of the head below the eyes". They are mostly found along the coast from Rockhampton to the Gulf of Carpentaria and have featured on the coat of arms since 1977 and has been the state bird since 1986. The red deer has a more regal origin; along with being a traditional and classic beast of heraldry, Queen Victoria gave the newly created colony a herd of deer from the royal hunting ground—hence their inclusion upon the
