Cummins & Partners Appoints Callum Walker as GM: What’s Next for the Agency? (2025)

The world of advertising is abuzz with a major leadership shift! Cummins & Partners, a renowned independent creative agency, has just announced a pivotal move, appointing Callum Walker as its new General Manager.

But here's where it gets emotional... This transition comes as the beloved Sarah Raine steps down after two impactful years at the agency's helm. Raine, a powerhouse in the industry, joined Cummins & Partners from Special Melbourne, where she served as Managing Director. Her journey included a stint as General Manager at Bullfrog and nearly six years at CHEP Network, making her departure a significant moment for the agency.

"Sarah has been an invaluable asset to Cummins & Partners and our clients," said Ben McCallum, CEO of Cummins & Partners. "We're grateful for her contributions and wish her the very best." Raine's legacy sets the stage for Walker's entrance.

And now, a new era begins. Walker, a strategic leader with a client-centric approach, is celebrated for his ability to foster high-performing teams, drive business growth, and produce award-winning creative and media campaigns. His background includes leadership roles at Special New Zealand and M&C Saatchi, as well as senior positions at iris Sydney, Clemenger BBDO, Host, and DDB.

"Callum's expertise will enhance our capacity to deliver integrated, powerful work for brands with big dreams," stated Sean Cummins, the agency's founder. McCallum echoed this sentiment, emphasizing Walker's alignment with the agency's philosophy: "He understands that creativity and strategy are inseparable, especially in an AI-driven marketing landscape."

Walker himself is enthusiastic about the opportunity: "Cummins & Partners has a remarkable 30-year history of innovation. They've pioneered the integration of creative and media, producing iconic work. I'm eager to leverage data and technology to build upon this rich legacy."

Cummins & Partners is celebrated for its unique approach, bringing creative and media together to craft ideas that influence behavior and elevate brands. By blending decades of expertise with cutting-edge tools like AI, they rapidly prototype and refine concepts, ensuring that campaigns resonate deeply. McCallum highlights the human element: "While technology offers a level playing field, it's our interpretation of data and creative application that sets us apart."

The agency's philosophy centers on attention as the ultimate currency in modern marketing. They believe in capturing attention through emotionally compelling creative and converting it into tangible results via data-driven, strategically guided media. Cummins & Partners seeks partnerships with brands that value ideas that resonate with audiences and media that delivers measurable impact.

As the agency welcomes Walker and bids farewell to Raine, a new chapter unfolds. But the question remains: How will Walker's leadership shape the agency's future, and what innovative campaigns will emerge under his guidance? Share your thoughts below!
