The Gold Coast is a coastal city located in the South East of the state of Queensland, Australia. The city is 94 km south of the state capital Brisbane. It is the second most populous city in the state, the sixth most populous city in the country, and also the most populous non-capital city in Australia. The Gold Coast also holds the title of the largest cross-state population of any metropolitan area in Australia, due to the inclusion of Tweed Heads, New South Wales in its metropolitan area. The Gold Coast's metropolitan area converges with that of Greater Brisbane, forming part of an urban conurbation of over 3 million people. The Gold Coast 600 (formerly known as Lexmark Indy 300) is a car racing event held annually, usually in October. The course runs through the streets of Surfers Paradise and Main Beach. The GC 600 comprises many other events such as the Indy Undie Ball and the Miss Indy Competition. Formerly an Indy car event, V8 Supercars are now the headline attraction, using the same track route. The Gold Coast street circuit is a high speed, concrete-lined, thrill ride that was shortened for the new-look event in 2010 by around 1.5-kilometres. The temporary street track has proven to create carnage in the past, particularly when drivers don’t show the patience required for victory, so the guest international drivers at this year’s event will have to tread carefully.
