Green Square station opened on 21 May 2000 when the
Airport line opened from
Central to
Wolli Creek. Like other stations on the line, Green Square was built and is operated by the
Airport Link Company as part of a
public–private partnership. Prior to March 2011, passengers were required to pay an access fee to use the station. The access fee was removed after the
State Government reached an agreement with the Airport Link Company to pay the fee at Green Square and
Mascot stations on behalf of passengers. Patronage increased by around 70% at the two stations in the months following the removal of the fee. From 2014 to 2017, patronage was growing at an annual rate of around 25 percent, leading to overcrowding at peak times. Green Square station featured in the music video clip for
Marvin Priest's "
Own This Club". ==Platforms and services==
