Southern Sydney to CBD public transport enhancement


The transport network between the Sydney CBD and the area south towards Sydney (Kingsford Smith) Airport lacks the capacity to effectively handle prospective population growth. The population of the Green Square Precinct is projected to grow from 33,000 in 2016 to 61,000 in 2031. While Green Square has a railway station on its western side, the north and east of Green Square make up a fast growing inner residential area that is not directly served by rapid public transport.

Green Square forms part of the nation’s largest bus transport task (Eastern Suburbs–South to Sydney Inner City), as identified in the 2015 Australian Infrastructure Audit. Due to road congestion, bus transport to the Sydney CBD from Green Square is slow and unreliable. Potential growth in bus transport, to service a larger population, will add to congestion close to the centre of Sydney.

With Green Square abutting the Sydney Airport precinct and close to the Port Botany precinct (which together generate more than $10 billion per year in economic activity), there is also an opportunity to grow commercial activity, facilitated by reliable, rapid public transport.

Proposed initiative

A high-capacity rapid transport link, either bus or rail, would provide significant additional capacity between the Sydney CBD and the unserved parts of the Green Square Precinct.

The New South Wales Government’s planning for Sydney Metro West includes consideration of a potential future station at Zetland.

The proponent for this initiative was previously the New South Wales Government. The initiative was updated in March 2018 to list the City of Sydney as the proponent.

Next steps

Proponent to identify initiatives and develop options (Stage 2 of Infrastructure Australia’s Assessment Framework).
