South Australia Government to invest AU$9.5 billion in infrastructure over the next 4 years

Major public transport projects, metropolitan and regional road projects, and a large-scale expansion of Australia’s first GigCity network top the State Labor Government’s 2017 Infrastructure Australia submission.

Infrastructure Australia – the Federal agency which prioritises national infrastructure projects - is preparing to publish a new Infrastructure Priority List in February next year.

The projects nominated by the South Australian Labor Government will underpin the State’s economic growth and jobs into the future.

They include:

Integrated Public Transport Initiative 

• A program of works including extending the Seaford train line to Aldinga, Park’n’Rides, interchange upgrades, increased public transport frequency, first mile/last mile access

Network Optimisation 

• A program of works (aligned to the National Network Optimisation Initiative) including upgrades to major intersections and level crossing removals at Park Terrace, Salisbury; Commercial Road, Salisbury; Womma Road, Elizabeth; Brighton Road, Hove; Goodwood Road, Goodwood; Marion Road/Cross Road, Plympton Park 

Improved Access to the State’s Far North & West 

• A program of works (aligned to the National Freight and Supply Chain initiative), including sealing and upgrading the Strzelecki Track, road upgrades from Adelaide to Port Augusta, and Port Augusta and beyond, duplication of the Joy Baluch AM Bridge in Port Augusta, key freight route upgrades - including resilience and access treatments to Yorkey’s Crossing, and regional aerodrome upgrades

Improved Access to Adelaide Airport 

• A program of works including intersection upgrades and new access to the terminal precinct for taxis, buses, freight and commercial vehicles, upgrades to public transport options (such as new tram link to the Adelaide Airport terminal) and more cycling and walking options 

Large-scale expansion of broadband infrastructure (GigCity Expansion) 

• With the successful implementation of Stage 1 of the GigCity Program, there now exists the opportunity to significantly expand Adelaide’s ultra-fast internet network to give access to even more data intensive companies.

The State Government submission also includes updates for the North-South Corridor and AdeLINK Tram Network initiatives.


The 2018 Infrastructure Priority List will build on the current list and update existing initiatives, with the State Government proposing new projects to reflect emerging infrastructure priorities across South Australia.

Currently 11 South Australian Government projects are included on the priority list including:
