The infrastructure sector’s sustainability achievements have been recognised, with the winners of the 2026 Infrastructure Sustainability Council Awards announced at IS Connect 2026.
The Infrastructure Sustainability Council (ISC) has announced the winners of its 2026 ISC Awards, recognising leadership, innovation and excellence in sustainable infrastructure across Australia and New Zealand.
The awards were presented during the IS Connect 2026 gala dinner, celebrating achievements across the infrastructure lifecycle, from policy and investment leadership through to project delivery, innovation and individual contributions.
ISC Chief Executive Officer, Toby Kent, said the record number of submissions reflected the growing maturity of sustainability and resilience practices across the sector.
“This year’s record number of submissions demonstrates that sustainability – and critically, resilience – are no longer aspirational concepts. They are embedded in how infrastructure is planned, delivered and operated across Australia and New Zealand,” Kent said.
“Our award winners are not only delivering outstanding projects and initiatives, they are setting new benchmarks for resilient infrastructure – assets that can withstand shocks, adapt to change, and continue to deliver lasting value for communities, the environment and the economy.”
More than 100 submissions were received for this year’s awards, the highest number in the program’s history.
Among the major winners, the Victorian Infrastructure Delivery Authority’s ecologiQ program took out the Industry Impact – Proponents, Policy and Investors category, while Infrabuild won the Supply Solutions category and Sustainable Built Environment National Research Centre (SBEnrc) was recognised in the Knowledge and Network category.
In the individual awards, Webuild Sustainability Engineer Devduni Chandraratne received the Emerging Leader award, while Arcadis Technical Director – Sustainability, Ken Lunty, was recognised for Enduring Impact.
Project Excellence Award winners included the Fitzroy to Gladstone Pipeline for Excellence in Economic Outcomes, joint winners Suburban Rail Loop East – Tunnels South and Metro Trains Melbourne for Excellence in Governance Outcomes, and Te Ara Tupua in New Zealand for Excellence in Environmental Outcomes.
The Outstanding Achievement – IS Rating Scheme award was presented to the METRONET Morley-Ellenbrook Line Project, delivered by the MELconnx Alliance, a partnership between Laing O’Rourke and the Public Transport Authority of Western Australia.
Kent said innovation was a defining feature of this year’s entries.
“What stands out this year is the depth of innovation – particularly in how organisations are embedding resilience alongside sustainability,” he said.
“From climate adaptation and circular economy solutions to stronger social outcomes, these projects show how infrastructure can be designed to endure, evolve and support communities through future challenges.”
The ISC congratulated all finalists and winners, as well as the independent judges, partners and industry participants who contributed to the success of the awards program.
