An Australian artificial intelligence infrastructure company called Firmus has secured a $10 billion debt funding package led by global investment firms Blackstone and Coatue Management. The financing will help the company build a major network of AI training and inference data centers across Australia under its Project Southgate initiative.
This development highlights how investment in physical AI infrastructure is growing worldwide as demand for high-performance computing continues to rise.
What the Funding Will Do
Scale AI Compute Capacity
Firmus plans to use the funds to expand its Project Southgate platform, which focuses on building large-scale AI facilities. The infrastructure will support both training and inference workloads, meaning it will help run and improve complex AI models.
The project is expected to eventually reach up to 1.6 gigawatts of compute capacity over the next few years. A gigawatt of capacity refers to the amount of power AI equipment can use, which reflects how large and energy-demand-intensive these facilities are.
Partnerships With Industry Leaders
Firmus is working with CDC Data Centres and Nvidia, a major U.S. chip maker known for its graphics processing units (GPUs). Nvidia’s processors are widely used for AI computing tasks. The collaboration supports a plan to create a network of AI-optimized data centers across Australia.
The deal follows other recent funding rounds for Firmus. In 2025, the company raised additional capital backed by Nvidia and Australian investors, signaling growing investor interest in sovereign AI infrastructure on Australian soil.
Why This Matters
The AI Infrastructure Trend
The AI industry is moving beyond software models to a physical layer of infrastructure that includes data centers, cooling systems, power supply and networking. These elements are essential to train and run state-of-the-art models that require significant computational power.
Countries like Australia are positioning themselves as competitive nodes in the global AI compute network by investing in both renewable energy and data-center capacity. This approach can attract international customers and provide local businesses with access to advanced compute resources.
Investment and Market Impact
Large debt financing of this scale signals confidence from major private equity investors in the long-term growth of AI infrastructure. For global technology markets, it reflects a shift in investor focus toward companies that build the hardware backbone of AI systems, not just the software.
This trend parallels other significant investments around the world, where companies and governments invest in large compute facilities to support research, enterprise use and cloud services for artificial intelligence.
Bottom Line
Australian AI infrastructure developer Firmus Technologies has secured a $10 billion debt financing package led by Blackstone and Coatue to accelerate its national rollout of AI data centers. The funding will support Project Southgate, a plan to build up to 1.6 gigawatts of AI compute capacity with partners such as CDC Data Centres and Nvidia. This deal underscores the growing focus on physical AI infrastructure and Australia’s role in the global AI ecosystem.
