Mascot station opened on 21 May 2000 when the
Airport line opened from
Central to
Wolli Creek. Like other stations on the line, Mascot 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 Mascot and Green Square stations on behalf of passengers. Following the removal of the fee, patronage increased by around 70% at the two stations in the months following, and passenger numbers rose substantially in the years following – with a 117% increase in ridership between 2015 and 2019. The concourse of Mascot station contains the Mascot Operations Room, which is responsible for operation of the four privately operated stations on the Airport line. At the platforms the station is signed "Mascot Suburban", to prevent confusion with the stations for the nearby airport, which is often referred to as Mascot Airport. Following the substantial increase in passenger numbers since the removal of the access fee, it was announced in June 2020 that a new entrance/exit was to be built. The existing station would also be upgraded, with additional ticket gates and public toilets. ==Platforms and services==
