Rod Laver Arena is a multipurpose arena located within Melbourne Park, in Melbourne, Victoria, Australia. The arena is the main venue for the Australian Open, the first Grand Slam tennis of the calendar year.HistoryReplacing the aging Kooyong Stadium, construction on the arena began in 1985 and was completed in 1987 at a cost of AU$94 million. It opened on 11 January 1988 for the 1988 Australian Open.Originally known in 1988 as the National Tennis Centre at Flinders Park, the arena has officially changed its name twice. First in 1996, when it was known as the Centre Court, and again in January 2000 to honour Rod Laver, a three-time winner of the Australian Open and one of the world's greatest tennis players.FeaturesRod Laver Arena has a seating capacity of 14,820, with a capacity of 15,400 for sports such as basketball, when extra seats are added around the court, and up to 16,200 for concerts with floor seating. The arena currently attracts over 1.5 million visitors per year.The arena was the first in Australia to have a retractable roof venue, and it is the largest indoor arena in Australia without a permanent roof (not counting the 56,347 seat Docklands Stadium, also in Melbourne, which is classed as a stadium rather than an arena). It is also the second largest indoor arena in Australia behind the 21,032 capacity Sydney Super Dome. The arena's retractable roof allows competitors to continue play during rain or extreme heat.
