TransLink is the public transit agency for Queensland, and is part of the Department of Transport and Main Roads. TransLink was first introduced by the Queensland Government in June 2003 to orchestrate bus, ferry, rail and services. TransLink works with Brisbane Airtrain (Airport services to Brisbane Airport), Transport for Brisbane, Transdev (Brisbane ferry services), Queensland Rail and other operators to provide services. TransLink operates an integrated ticketing system and the "go" card system to allow the use of one ticket on multiple services.
