Steel: the strength behind Australia’s Nation Building

13 February 2023

Across Australia, construction and infrastructure projects are providing a major boost to the economy. As the nation emerges from the COVID-19 pandemic, it’s large-scale building projects and road and rail infrastructure which is helping build the nation.

We are proud of our long-standing and ongoing role in contributing to Australia’s built environment, and continuing to support and stand with the construction industry and partners as the revitalisation of our towns and cities is underway. We’re also proud of our teams and the skills and capability of our people who bring their expertise to these projects around the country.

Here are the major projects we’re celebrating.


Western Sydney International airport – Baggage Handling System (BHS) & Passenger link bridges (PLB) – Australia’s first modern baggage handling system will be a game changer for anyone catching a plane from Western Sydney International (Nancy-Bird Walton) Airport when it opens in late 2026. Western Sydney Airport CEO Simon Hickey said the baggage handling system will help deliver a fast and easy experience for passengers and airlines and make Sydney’s new airport one of the most advanced airports in the world. InfraBuild is set to supply over 1800 tonnes of structural, tubular and plate steel.


Maroochydore Road and Mons Road Interchange – Another milestone in the delivery of Queensland’s Bruce Highway upgrade has arrived with the commencement of the Maroochydore Road to Mons Road Interchange package of works. The project includes a new, 4-lane eastbound bridge over the Bruce Highway from Nambour Connection Road to Maroochydore Road, converting the roads’ existing roundabout to a signalised interchange, and upgrades, relocations, and removals of existing off and on ramps. Partnering with John Holland Seymour Whyte Joint Venture, InfraBuild will provide 2,000 tonnes of reinforcing steel to the project which, upon completion in 2022, will signal the beginning of the final push in the 15-year long delivery of the $12.6 billion Bruce Highway project.

Queens Wharf – InfraBuild has kept the Queen’s Wharf project ahead of program by accelerating its supply of reinforcing steel to site for two of the project’s large raft slabs. Approximately 700 tonnes of reinforcing has been used in the two slabs, which form a base for two of the four towers that will make up Brisbane’s $3.6bn Queen’s Wharf Brisbane Integrated Resort Development.


Melbourne Metro Tunnel – This major project is set to deliver five new underground stations to increase capacity by 504,000 passengers during its seven year construction timeframe. Its aim is to alleviate the city’s congested City Loop by diverting its busiest line through the new twin tunnels. InfraBuild has been collaborating closely with the Cross Yarra Partnership to supply Australian-made reinforcing steel. From specialised diaphragm wall cages which allowed TBMs to breakthrough without damage, to large scale prefabrication of slab inverts, station columns, and roof beams requiring 3D BIM, InfraBuild has been an essential partner in the delivery of the project’s new underground stations.


Yanchep Rail Extension and Thornlie-Cockburn Link – Following the successful supply of reinforcing steel to the Forrestfield-Airport Link, InfraBuild is proud to continue to be a part of Western Australia’s rail infrastructure development by partnering with the NEWest Alliance to deliver 14 000 tonnes of reo to the Yanchep Rail Extension and Thornlie-Cockburn Link. Improving public transport for Perth’s growing northern corridor and facilitating more flexible train travel for the city’s southern suburbs respectively, the Yanchep Rail Extension and the Thornlie-Cockburn Link are the latest package of works to be commenced as part of the State Government’s METRONET program.
