The $472 million Cairns Water Security project has reached a major construction milestone, with work continuing on the new intake, treatment plant and distribution network, designed to strengthen long-term supply for the region.
Since construction began in July 2024, more than one million hours of labour have been logged across the project, which is jointly funded by the Australian and Queensland governments through the National Water Grid Fund and delivered in partnership with Cairns Regional Council.

What progress has been made on site?
More than 25 kilometres of the planned 30-kilometre distribution pipeline has now been installed, with major works underway at the Mulgrave River intake, the new water treatment plant and associated reservoir infrastructure.
The project has also directed significant investment into the regional economy, with more than $100 million spent through 140 local suppliers. Of the 1,100 people involved in the project, more than 80 per cent are based in the Cairns region.
Major construction is scheduled for completion by mid-2026, followed by commissioning, subject to weather conditions.
How will the project strengthen Cairns’ water security?
Queensland Minister for Local Government and Water Ann Leahy said the project was central to supporting growth in the Cairns region.
“Water is critical for the prosperity and sustainability of our Queensland communities, and we know this project is critically needed for the growing Cairns population,” Minister Leahy said. “Once complete, it will deliver a resilient, reliable water network that is built to support the future water needs of Cairns and nearby Gordonvale.
“This project is growing our economy to help drive down the cost of living and support a better lifestyle for North Queenslanders, with real benefits already flowing through new local jobs and investment.
“This milestone reflects the strong partnerships between local, state and federal governments to deliver essential infrastructure for Queensland’s future.”
Federal Member for Leichhardt Matt Smith said the works were generating immediate economic benefits.
“It’s fantastic to see the construction process supporting local jobs and businesses, relying on local know-how and pumping funding into the region,” Smith said. “This project will continue to have lasting benefits for Cairns by delivering a reliable, clean water supply for the future.”
Cairns Mayor Amy Eden said recent water restrictions and extreme weather had reinforced the importance of the investment.
“Reaching one million work hours is a significant milestone for the community, particularly following recent water restrictions and weather events,” Mayor Eden said. “Recent conditions have been a clear reminder of how vulnerable our water supplies can be, and why this project matters.
“This milestone shows we are taking responsible, long-term action to secure Cairns’ water future. Water security underpins our lifestyle, our environment and our ability to grow sustainably, and this project ensures Cairns is better prepared for the decades ahead.”
Assistant Minister for Far North Queensland Bree James said the infrastructure build was also strengthening the regional economy.
“Projects like this are vital to deliver on local needs and drive economic growth across Far North Queensland,” James said. “By investing in essential infrastructure, we’re not only ensuring water security but also creating jobs, supporting local businesses, and building a stronger, more resilient regional economy.
“This project is shining a light on the incredible local talent and capability of our region. This truly is a project built by the people of Cairns, for the people of Cairns.”
