The Gold Coast is the largest regional city and fastest growing city in Australia. As a result, the Gold Coast has a wide range of public and private transport options from cars and bikes to buses, heavy rail and light rail. The car is the dominant mode of transport in the city with an extensive arterial road network that connects the standard residential streets with major suburbs and motorways. Public Transport on the Gold Coast is managed by the Queensland Government's Department of Transport and Main Roads, while Translink coordinates the Transport network in South East Queensland.
