The economy of Queensland is the third largest economy within Australia. Queensland generated 19.5% of Australia's gross domestic product in the 2008-09 financial year. The economy is primarily built upon mining, agriculture, tourism and financial services. Queensland's main exports are coal, metals, meat and sugar. Western Australia and Queensland are often referred to as the "resource states" because their economies are currently dependent on exports of resources such as coal, iron ore and natural gas. However, of the two states, Queensland has a more diversified base. In 2006, exports from Queensland totaled A$49.4 billion. By 2009 this figure had grown to A$65.5 billion. Brisbane is categorised as a global city, and is among Asia-Pacific cities with largest GDPs. It has strengths in mining, banking, insurance, transportation, information technology, real estate and food. Some of the largest companies headquartered in Brisbane, all among Australia's largest, include Suncorp Group, Virgin Australia, Aurizon, Bank of Queensland, Flight Centre, CUA, Sunsuper, QSuper, Domino's Pizza Enterprises, Star Entertainment Group, ALS, TechnologyOne, NEXTDC, Super Retail Group, New Hope Coal, Jumbo Interactive, National Storage, Collins Foods and Boeing Australia. In 2018, there were 134,312 international students enrolled in the state, largely focused on Brisbane. Most of the state's international students are from Asia. Agriculture In 2011, the Australian Bureau of Statistics recorded a total of 28,435 farms covering 81% of the state. Sugar cane is harvested in coastal areas from Far North Queensland to the southern border and is the state's biggest rural commodity. Queensland produces 94% of Australia's total raw sugar production. Customers in the Asia-Pacific region can be supplied all year round through the use of storage facilities at bulk port terminals. Most of the state's sugar crop is marketed through Queensland Sugar, which until 2006 compulsorily acquired all sugar grown in the state under a single desk arrangement. Cattle grazing for beef and sheep grazing for wool production are spread across inland areas. Wheat is grown in the Darling Downs region, an area that has seen mining activities expand. This has produced a boom in construction work for the region despite the global downturn but created conflict between farmers and mining companies. The Lockyer Valley is a significant horticultural region, although persistent drought is forcing the local economy to diversify. Farms around the coastal town of Bowen produce Australia's largest winter crop of vegetables. Other major crops produced in Queensland include bananas, cotton and
