Landmark Energy Investment Headlines Queensland Budget
The Queensland State Budget 2025–26 has delivered a historic commitment to infrastructure, with a $2.4 billion funding injection into the CopperString 2032 project—a massive step forward in Australia’s energy and mining development. This substantial allocation positions CopperString as the nation’s most ambitious energy transmission project, creating a direct high-voltage link between Mount Isa and the National Electricity Market (NEM).
Described by government officials as a “nation-building investment,” the funding underscores Queensland’s intent to become a leader in critical mineral extraction, regional industrial growth, and clean energy transmission.

What is CopperString 2032?
Originally proposed over a decade ago and revitalised in recent years, the CopperString 2032 project is a 1,100-kilometre high-voltage transmission line that will connect the resource-rich North West Minerals Province with the state’s electricity grid. It is expected to unlock access to vast reserves of copper, zinc, vanadium, and rare earths, enabling new mines to come online and existing operations to expand with affordable, grid-connected power.
The project is also designed to integrate renewable energy zones in northern and western Queensland into the broader grid, enhancing reliability and reducing dependence on diesel generation.
“This investment isn’t just about infrastructure—it’s about unlocking Queensland’s future,” said Deputy Opposition Leader David Janetzki, who praised the project’s potential for both industry and decarbonisation.
CopperString 2032 Funding Boost: What’s in the Budget?
The newly allocated $2.4 billion in CopperString funding is the largest single infrastructure line item in the 2025–26 Queensland Budget. The money will be directed toward:
- Completion of route planning and land acquisition
- Construction of transmission towers and substations
- Labour force expansion and contractor mobilisation
- Connection upgrades for Mount Isa and Cloncurry
- Integration of renewable energy nodes in Hughenden and Julia Creek
With this boost, the project’s total funding now exceeds $5 billion, combining federal contributions, private equity, and previous state allocations.

Strategic Importance for Mining and Minerals
The Queensland CopperString investment is not solely about energy—it’s a mining strategy. The North West Minerals Province is one of the most prospective regions in Australia for copper, a metal crucial to the global transition toward electrification.
New deposits in the region have long faced development delays due to lack of affordable and stable power. With CopperString now progressing, companies operating in areas such as Mount Isa, Ernest Henry, and Cloncurry are revising their production forecasts and investment plans.

“The economics of remote mining change significantly when power costs fall and carbon intensity drops,” said a senior analyst at the Australian Resources and Energy Group.
This transmission line could be the difference between project shelving and project execution.
Unlocking Renewable Energy Zones
Beyond mining, the CopperString renewable energy connection is key to Queensland’s net-zero transition. The transmission corridor is designed to tap into wind and solar farms being developed across the inland northwest, bringing clean power to the grid and supplying industrial customers with green electricity.
The state government expects up to 5 GW of renewable generation capacity could be connected via CopperString by 2032.
This capability places Queensland at the centre of a larger vision for interconnected, renewable-led energy systems, serving not only miners but also manufacturing and export hubs seeking clean energy certification.

Political and Regional Support
The CopperString 2032 funding boost has been met with strong bipartisan support and backing from regional councils. Community leaders in Charters Towers, Hughenden, and Mount Isa say the project will bring lasting economic benefits, including thousands of construction jobs and long-term roles in energy and maintenance.
Despite initial concerns over delays and rising material costs, the Queensland Government insists the project is on track for major construction to begin in early 2026, with first transmission scheduled for late 2028.
Conclusion: Powering the Future of Queensland
The 2025–26 Queensland State Budget has delivered more than just numbers—it’s made a long-awaited commitment to one of the state’s most transformational infrastructure projects. With the CopperString 2032 funding boost, Queensland is not only connecting wires across vast distances but also linking mining, energy, and regional development into one unified vision.
In a future defined by clean energy, copper demand, and digital infrastructure, CopperString is fast becoming the literal and symbolic conduit powering Queensland’s economic ambitions.
