Cairns Infrastructure Boom: Major Projects Reshaping the City and Its Future

Cairns is in the midst of an infrastructure transformation. Multiple major projects, spanning water security, transport, health and marine industry, are either underway or on the drawing board, promising to reshape the city for decades to come. For local residents, the impact will be felt in everything from daily commutes to long-term community resilience.

Water Security Takes Priority

The largest single project ever undertaken by Cairns Regional Council is the Cairns Water Security Stage 1, a $325.5 million drinking water supply initiative. Construction has been awarded to John Holland Qld and will feature a new intake on the Mulgrave River. The project, listed as being in the planning and design phase on the council's major projects page, is a critical investment for a region that has faced water supply challenges and is expected to support population growth and future development. For residents, it means a more reliable and secure water source, reducing the risk of restrictions during dry periods.

Roads, Hospitals and Jobs

Transport upgrades are also making headway. The Bruce Highway, Cairns Southern Access Stage 3, connecting Edmonton to Gordonvale, is a $535 million project nearing completion, with the Australian Government contributing $428 million. Meanwhile, the Captain Cook Highway upgrade from the Cairns CBD to Smithfield is a $359 million initiative-$287.2 million from the federal government and $71.8 million from the state-with early works expected to be done by late 2025. These road projects will ease congestion and improve safety for thousands of daily commuters.

In health, the Cairns Hospital Expansion Project is adding 64 beds at a cost of $171 million. Early refurbishment works are already underway, and a new 53-bed Mental Health Inpatient Service building opened in February 2025. These additions will help meet growing demand for hospital services in the region.

On the economic front, the $180 million Cairns Marine Precinct, set to include a 5,000-tonne ship-lift and three hardstand areas, is expected to begin construction later in 2026. The project is projected to create 460 construction jobs, boosting local employment and supporting the marine industry.

Airport Upgrades

Cairns Airport is also investing heavily in its facilities. Two major redevelopment projects are underway: a $60 million Eastern Aviation Precinct and a $55 million international terminal upgrade-the first major refresh of that terminal since it opened more than 30 years ago. These upgrades will improve the travel experience for locals and visitors alike, supporting tourism and business connectivity.

What Comes Next

Many of these projects are progressing through various stages. The council's major projects page shows the flood recovery program is also active, reflecting ongoing community resilience efforts. Residents can expect continued construction activity across the city in the coming months and years. While exact completion dates vary, the long-term benefits-from safer roads and expanded hospital capacity to a secure water supply-are set to significantly improve daily life in Cairns.
