John Cain Arena is a multi-purpose sports and entertainment arena located within Melbourne Park in Melbourne, Victoria, Australia. It is the second-largest venue and show court for the Australian Open, the first Grand Slam professional tennis tournament held each calendar year. The arena also hosts various other sporting and entertainment events throughout the year. The arena has sometimes been dubbed "The People's Court" during Australian Open matches. This is due to its accessibility to patrons holding a ground pass - the cheapest ticket category available - and the close proximity of spectators to the players. The venue is known for its atmosphere, particularly during matches involving Australian players. Construction commenced in the late 1990s, and was completed in 2000. The arena features a cycling track, which is covered over with seating for court events. The tennis court is a GreenSet surface (between 2008 and 2019 the surface was Plexicushion) and the roof is retractable, making it one of the few venues where tennis can be played during rain. The venue is able to hold a maximum spectator capacity of 11,000 for events such as music concerts where general floor seating or standing room is available. For basketball, netball and tennis the capacity is 10,500. When the velodrome is in use the northern and southern banks of seats, which cover the turns of the velodrome, are raised to reveal the track while the floor seating is removed leaving a reduced capacity of 4,500. Following the renovation of the Margaret Court Arena as part of a A$363 million upgrade to Melbourne Park in time for the 2015 Australian Open, which included a retractable roof and an increase in capacity from 6,000 to 7,500, both Melbourne United (formerly the Melbourne Tigers) and the Melbourne Vixens announced their intentions to move from the arena to the smaller capacity Margaret Court Arena (MCA) from 2015. However, Melbourne United abandoned their move to MCA after the 2015-16 NBL season
