The Big Day Out (BDO) was an annual music festival that was held in five Australian cities: Sydney, Melbourne, Gold Coast, Adelaide, and Perth, as well as Auckland, New Zealand. The festival was held during summer, typically in January of each year but was sometimes held as late as early February in some cities including Perth.

The Gold Coast, often referred to by its initials G.C., is the second-largest city of Queensland, Australia, after Brisbane. It is Australia's sixth-largest city, the most populous non-capital city, and the state's after Brisbane, with a population over 600,000. The Gold Coast is a coastal city and region located approximately 66 kilometres (41 mi) south-southeast of the centre of the state capital, Brisbane. The city's central business district is located roughly in the centre of the Gold Coast in the suburb of Southport. The urban area of the Gold Coast is concentrated along the coast, sprawling almost 60 kilometres, joining up with the Greater Brisbane metropolitan region to the north and to the state border with New South Wales to the south. Nicknames of the city include the ‘Glitter Strip’ and the ‘Goldy’. The demonym of a Gold Coast resident is Gold Coaster.
