Publicis Groupe’s Zenith has taken the top spot in Comvergence’s latest Australian media agency rankings, winning and retaining US$120 million (A$175 million) in business in 2025.

The rankings, which account for new business wins, retentions and losses over the year, place WPP Media’s Mindshare and Essence Mediacom in second and third, with US$112 million and US$110 million respectively. Notably, Mindshare’s total was driven entirely by new client wins.

Independent agency Brainlabs and Omnicom Media Group’s PHD rounded out the top five, recording US$64 million and US$53 million in total business wins for the year, according to the France-based media performance monitor.

Under the leadership of local CEO, Jason Tonelli, Zenith Media Australia last year won new accounts with the likes of Flight Centre and Honda.

At a holding company level, Publicis Media ranked first with US$208 million in total business won and retained, followed by WPP Media on US$194 million.

Independent network Nunn Media placed third with US$28 million, while Havas Media Network ranked fourth with US$25 million in total billings.

In a statement, Publicis ANZ CEO Michael Rebelo said the local holding company had “built real momentum over time, driven by a relentless focus on our clients, capability enhancement, talent magnetism and innovation in data and technology”.

“These results are not just reflective of new business won but also how we are retaining our current clients. For that, I am incredibly proud of our media leaders and teams,” he added.

Comvergence’s results come just days after fellow French media agency monitor Recma released its qualitative assessment of Australian media agencies, which evaluates new business, capabilities and client base.

This saw the newly combined Omnicom–IPG Mediabrands holding company make its debut on Recma’s rankings, landing just behind market leader WPP Media, even as its individual organisations slipped in the scoring.

WPP Media, meanwhile, maintained its 56-point lead and Omnicom-IPG combined took 54 points. Publicis jumped from 42 to 48 points, while Dentsu slipped from 15 to 13 and Havas Media fell from three to two.

On the agency front, EssenceMediacom maintained its number one spot, earning top marks for “vitality” and “structure” ahead of OMD, with fellow WPP Media agency Mindshare in third.

“Our ambition is limitless growth for clients, our people and partnerships,” Aimee Buchanan, WPP Media CEO ANZ said in a statement.

“We are super proud that this has carried through our full year 2025 new business results. We have a strong track record across new business and retentions, which reflects the investment we’ve made in future-facing capabilities and in our people and our leadership across the group. Having both Mindshare and Essence Mediacom ranked joint number two is also a great credit to the leadership from Maria Grivas and Pippa Berlocher and their teams.”
