In Australia’s push for energy security, digital capacity and connected communities, Castle Group is building from the ground up.
The Sydney-based, founder-led company has moved from property into a diversified platform covering battery-based energy storage systems, data centers, property and hospitality. Its edge is rooted in a discipline Japanese investors know well: originating land, securing approvals and staying patient enough to build durable value.
“Our growth has never been about pursuing specific sectors. It has been about recognizing where long-term demand is heading and building the capability to meet it,” said Ritchie Perera, founder and group CEO.
That approach is now moving into larger infrastructure-led opportunities. In March, two Castle Group battery storage projects were endorsed by the New South Wales government’s Investment Delivery Authority as strategically significant energy projects, strengthening the group’s role in Australia’s energy transition.
“Energy and digital infrastructure are no longer adjacent to development. They are fundamental to how cities function and how economies grow,” Perera said.
“Our growth has never been about pursuing specific sectors. It has been about recognizing where long-term demand is heading and building the capability to meet it.”

Castle Group’s development platform gives that ambition weight: 10 gigawatt-hours of battery energy storage across Sydney and 750 megawatts of data center capacity. Its residential pipeline totals 2 billion Australian dollars ($1.43 billion) across 15 projects, including two joint ventures with Kanden Real Estate Development, a subsidiary of Kansai Electric Power Co.
For Japanese investors, Castle Group offers access to institutional-grade real asset opportunities and cultural alignment across Australia’s energy, digital infrastructure and property sectors.
“Our partnerships with Japanese institutions reflect a shared approach to investment. It is disciplined, considered and focused on long-term outcomes rather than short-term return,” Perera said.
With government recognition, a diversified pipeline and Japanese partners part of its growth story, Castle Group is positioning itself for the next generation of Australian infrastructure, where land, power and long-term capital meet.
