303 and Pembleton form strategic alliance

Under the agreement, the three agencies will collaborate on projects and share resources where capabilities align

Independent agency 303 and sister media agency Mediahub have formed a strategic alliance with Melbourne-based creative agency Pembleton, expanding their national footprint and broadening the specialist services available to clients.

Under the agreement, the three agencies will collaborate on projects and share resources where capabilities align, while maintaining separate ownership structures and agency brands. The alliance strengthens 303 and Mediahub's presence in Melbourne, alongside their existing operations in Perth and Sydney, while giving Pembleton greater reach beyond Victoria.

Alliance expands national capabilities

303 said the partnership reflects growing demand from clients for senior agency talent across multiple locations and integrated services delivered through flexible teams.

The alliance builds on longstanding professional relationships between the agencies. Pembleton directors Alex Speakman, Simon Bagnasco and Mac Wright previously worked with 303 Executive Chairman Anthony Gregorio at Saatchi & Saatchi Australia.

Anthony Gregorio, Executive Chairman, 303: "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."

Independent model remains in place

Pembleton said the alliance will allow it to expand its geographic reach while maintaining its independent operating model.

Matilda Hobba, Director and Managing Partner, Pembleton: "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. Importantly, by remaining completely independent, we both retain the ability to structure our respective projects and clients in the way that gets the best outcomes."

Builds on independent strategy

The alliance follows 303's decision in December 2025 to return to independent ownership, removing the MullenLowe brand while continuing to offer integrated creative, media, strategy, digital, public relations and retail activation services alongside Mediahub.

The agencies have since secured new business, including Australian Cancer Research Foundation and Cancer Council's Australia's Biggest Morning Tea campaign. More recently, 303 Mediahub was appointed to the Western Australia Government Common Use Arrangement panel for media strategy and buying.
