Terminal 1 was opened on 3 May 1970, replacing the old Overseas Passenger Terminal. Terminal 1 has been greatly expanded since then. Today it is known as the International Terminal, in the airport's north western area. It has 30 gates (Concourse B with 8–37 and Concourse C with 50–63) served by aerobridges, as well as a number of remote bays. It has room for the Airbus A380, which fly routes to Singapore (Singapore Airlines), London via Singapore and Los Angeles (Qantas), Dubai and Auckland (Emirates). The terminal building has three levels, one each for arrivals, departures and airline offices. The departure level has 20 rows of check-in desks, each with 10 single desks making a total of 200 check-in desks. The terminal also has an observation deck on the roof. The terminal has six airline lounges: Two for Qantas, and one each for Air New Zealand, Singapore Airlines, Malaysia Airlines and Emirates. The terminal underwent a major $500 million redevelopment that was completed in 2010. The shopping area was made bigger, outbound customs operations were put into one place, and the floor space of the terminal increased to 254,000 square metres.
