Macquarie Technology Group today announced the appointment of Luke Clifton as Director of Macquarie Technology Operations Pty Ltd as the company continues to scale across telecommunications, cloud, cybersecurity, and data centres.

Clifton, who after nearly 15 years in senior leadership, including more than a decade leading Macquarie Telecom, has chosen to transition to the next chapter of his career, focusing on governance, board, and advisory work. Luke played a central role in Macquarie’s SD-WAN evolution, cybersecurity and cloud enablement, and more recently the expansion of major partnerships including VeloCloud, Fortinet, and Netskope.

Luke will continue to support the business throughout the handover period and his appointment as Director ensures his experience and perspective continue to inform the company as it scales.

“Luke has made an extraordinary contribution to Macquarie Telecom over the past 15 years. He has shaped our challenger ethos, led the introduction of SD-WAN to the Australian market, championed our SoUnTelco approach, strengthened our cyber and cloud capabilities in the mid-market, and built enduring customer and vendor partnerships,” said David Tudehope, Macquarie Technology co-founder and CEO.

As part of this evolution, Marija Harris has been appointed Group Executive, Macquarie Telecom, effective early 2026.

Marija, who has previously held senior roles at Foxtel and Virgin, has served as Commercial Director for the past two years at Macquarie Telecom and has been a key contributor to the company’s strategy, financial performance, and customer growth.

“Marija is a highly respected leader within Macquarie and in the industry. She brings deep commercial insight, a strong customer mindset, and a collaborative leadership style that aligns with our culture and our growth ambitions,” said Tudehope. “The Board and I are delighted to appoint her as Group Executive for the next phase of our journey.”

Reflecting on his transition, Luke Clifton said his focus is shifting toward governance and long-term stewardship.

“Macquarie has been a defining chapter in my life and career and I am incredibly proud of what our team has achieved – from our SD-WAN leadership to our work with nbn, our cyber and cloud growth, and our commitment to onshoring Australian jobs. After much reflection, I feel this is the right moment to transition to a governance and advisory portfolio.”

In addition to his new Board role, Luke will continue as Chair of the Australian Men’s Shed Association, where he has been leading national strategic initiatives in men’s mental health and community impact.

According to Clifton, Marija is a leader of exceptional capability and character. “She understands our customers deeply, knows the business intimately, and has my full confidence. I look forward to supporting her through the handover and continuing my involvement with the Group through the Macquarie Technology Operations Board.”

The leadership changes will be implemented progressively over the coming months, with a structured program of engagement with customers, partners, and employees to ensure continuity across the business.
