Quinbrook Taps Australian Lead for Global CEO Role | ASX All Ordinaries Sector View

Highlights

• Brian Restall to become global CEO of Quinbrook Infrastructure Partners

• New leadership team unveiled across North America and digital infrastructure

• Organisational changes aim to strengthen Quinbrook’s global clean energy focus

Quinbrook Infrastructure Partners has announced a major leadership transition with Brian Restall, its Australian regional leader, stepping into the newly created global chief executive officer role by year-end. The move marks a significant evolution in the firm’s management structure as it continues expanding across North America, Europe, and Australia, where it actively supports clean energy and infrastructure assets.

The announcement comes as global energy transition strategies drive demand for executive leadership with deep project development and investment execution expertise — areas in which Restall has been active since Quinbrook's inception.

Long-Standing Partnership Anchors Global Strategy

Brian Restall has worked alongside Quinbrook’s founder since 2011 and was part of the firm’s launch in 2015. Over the course of his career, Restall has led substantial energy infrastructure efforts, including large-scale project development and asset construction. He was also the inaugural CEO of Cape Byron Power, Quinbrook’s first portfolio company, offering him foundational insight into scaling early-stage renewable platforms.

His elevation to the global CEO position signals a drive to harmonise regional investment execution with the firm’s overarching strategic priorities in clean energy and digital infrastructure development.

New North America Leader Brings Policy and Strategy Expertise

Alongside Restall’s transition, Quinbrook has appointed Giulia Siccardo as the new regional head of its North American operations. Previously a partner at McKinsey & Company, Siccardo recently served as the first director of manufacturing and energy supply chains at the US Department of Energy. Her government role involved leading a newly formed investment arm aimed at accelerating domestic clean energy manufacturing.

Siccardo replaces John Lucas, who departs at the end of the month, and is expected to bring a combined perspective of private-sector innovation and public-sector implementation to Quinbrook’s US-led initiatives.

Digital Infrastructure Leadership Strengthened

Further reinforcing its strategic verticals, Quinbrook has also promoted Kathryn Lin to senior director. Lin will lead the firm’s digital infrastructure platform from within the North American investment team, focusing on data centres and associated clean power solutions. Her new role highlights the growing intersection between energy infrastructure and digital connectivity — a sector increasingly prioritised by institutional investors and sustainability-focused platforms.

Lin’s promotion reflects a broader trend across Quinbrook's operations to elevate internal talent and expand capacity in sectors such as energy storage, grid modernisation, and data-driven power systems.

Global Focus Sharpens on Clean Energy Investment Deployment

These appointments represent a shift toward deeper global alignment across Quinbrook’s platform as the firm scales its development pipeline and continues delivering low-carbon infrastructure solutions. With Australia, North America, and Europe as key markets, the structural adjustments aim to consolidate leadership capabilities and support agile decision-making across multiple jurisdictions.

Quinbrook’s evolving management structure supports its mission to deploy capital across the clean energy spectrum, focusing on real asset development that underpins renewable energy, resilient power systems, and sustainable data infrastructure. The announcement positions the company to meet expanding market demands through a renewed leadership framework grounded in regional experience and sector-specific depth.
