In her new role, Ms Clarke will oversee the delivery of Castle Group’s $1.6 billion project pipeline and lead the company’s expansion.

Castle Group Founder, Ritchie Perera, will transition to the role of Group CEO – stepping back from day-to-day operations to enable him to focus on shaping the group’s long-term strategy.

“I am energised by the opportunity to lead the creation of the next generation of urban places – vibrant, sustainable, and inclusive communities designed to leave a lasting legacy,” Ms Clarke said.

With more than two decades of experience shaping Australia’s urban landscape, Ms Clarke brings deep strategic insight, commercial acumen, and proven ability to deliver transformative change. She most recently served as Managing Director of Communities at Lendlease and is currently President of the Property Council of Australia’s NSW Division.

Mr Perera said Ms Clarke’s appointment marks an exciting new chapter for Castle Group.

“Ranisha is widely recognised for her ability to balance commercial success with community and environmental integrity. Her leadership will accelerate Castle Group’s mission to create places that not only perform, but endure – driving growth, sustainability and innovation across every project,” he said.

Beyond her executive career, Ms Clarke is an influential industry voice, contributing to advisory councils and boards focused on urban planning, sustainable development and the transition to a low-carbon community.

“My focus is on aligning investment, innovation and impact, while creating the conditions for growth that deliver long-term social and economic value,” Ms Clarke said
