For more than 20 years, Castle Group has worked in Western Sydney – shaping places where people live, work and build their future. That experience has reinforced a simple truth: strong communities depend on reliable infrastructure that supports everyday life.​

Electricity, digital networks and modern work environments underpin homes, schools, hospitals, emergency services, businesses and local jobs. Much of this infrastructure operates quietly in the background, but as cities grow, its importance becomes increasingly visible.​

Castle Group’s infrastructure work builds on decades of experience in careful planning, long-term thinking and early engagement. Our focus is on supporting essential energy and digital infrastructure in ways that are responsible, transparent and subject to independent assessment and regulatory oversight.​

Castle Group has secured 1.5GW of strategically located, powered land across Sydney, Australia for Data Centres, alongside a further 2GW utility-scale BESS projects.

Combined with Data Centres, Castle Group is uniquely positioned to deliver valuable infrastructure for Sydney and Australia’s digital economy.
