Independent media agency Nunn Media has appointed Belinda Miller as head of growth, creating a new role to support its expansion in Sydney and across NSW.
Based in Sydney, Miller will report to managing director Chris Walton and work with the agency’s leadership team to drive new business and strengthen client partnerships across its full-service offering.
Miller joins from Havas Media, where she served as head of partnerships & growth, leading investment negotiations across broadcast, digital, out-of-home and streaming.
She brings more than 25 years’ experience across media, agencies, publishing and sport, having also held roles including head of content at Havas Play, group business director at Nine and general manager at Social Soup.
Walton said Miller’s commercial experience and relationship-building skills made her well suited to the newly created position.
“Growth at Nunn has always come from relationships and results, and Bee has built her career on both,” Walton said.
“Her commercial instincts, her depth across media, content and partnerships, and the way she works with people make her the right person to lead this next chapter for our clients and our team.”
Miller said she was looking forward to helping more brands explore what the agency could offer.
“I’ve always been passionate about connecting with clients, brands and people, and turning those connections into commercial success,” she said.
“Nunn is an independent, future-led agency with a brand-first focus, and it’s genuinely invested in its people and its technology. I’m excited to help more brands discover what that makes possible.”
The appointment comes as Nunn Media invests in Kaspar, its proprietary platform combining data, technology and AI-enabled planning, activation and measurement.
The agency has also expanded its digital capabilities through acquisitions including Alley Group, indago digital and Innovate Online.
Its recent client wins include Australian Unity and Dairy Australia, adding to a roster featuring Spotlight Retail Group, SunRice, Philips, JB Hi-Fi, Aussie Broadband and Silversea Cruises.
