Australia – Australian integrated agency 303 and sister media agency Mediahub have formed a strategic alliance with Melbourne-based creative agency Pembleton, expanding their national footprint and specialist capabilities while maintaining independent operations.
Under the alliance, the three agencies will collaborate on projects and share resources where capabilities align, while retaining their individual ownership structures and brands.
The move strengthens 303 and Mediahub’s presence in Melbourne alongside their existing operations in Sydney and Perth, while giving Pembleton access to on-the-ground support beyond Victoria.
Anthony Gregorio, Executive Chairman at 303, said evolving client expectations and opportunities in the Melbourne market drove the partnership.
“In a world where the agency landscape is changing rapidly, clients increasingly want experienced senior people in multiple locations actively working on their business. This alliance allows senior talent from both organisations in several Australian markets to collaborate closely and deliver seamless outcomes for clients, while remaining agile and efficient.”
The alliance builds on longstanding relationships between the leadership teams.
Pembleton Directors Alex Speakman, Simon Bagnasco and Mac Wright previously worked with Gregorio at Saatchi & Saatchi Australia, creating what the agencies described as a strong foundation of trust and collaboration.
Matilda Hobba, Director and Managing Partner at Pembleton, said the arrangement enables the agency to broaden its reach without compromising its independent operating model.
“Pembleton’s model has always seen senior brains on the tools end-to-end, supported by bespoke specialist teams to execute the thinking. The alliance with 303 provides Pembleton with a greater pool of specialists to tap into on the projects that need it, along with the opportunity to support our friends at 303 where relevant.”
She added that remaining independent allows both agencies to continue structuring projects and client relationships in the way that delivers the strongest outcomes.
Gregorio said the agencies share an entrepreneurial culture that extends beyond the partnership’s commercial objectives.
According to Gregorio, the combined expertise will help both businesses pursue growth opportunities while expanding their integrated service offering across strategy, creative, media, digital, PR and retail activation.
The alliance follows 303’s return to independent ownership after dropping the MullenLowe branding in December 2025.
At the time, the agency reaffirmed its integrated business model by bringing together its creative, media, strategy, digital, PR and retail activation capabilities alongside Mediahub.
Since the rebrand, 303 and Mediahub have secured new client wins including the Australian Cancer Research Foundation and Cancer Council’s Australia’s Biggest Morning Tea.
The agencies were also recently appointed to the Western Australian Government’s Common Use Arrangement (CUA) panel for media strategy and buying.
