Nick Garrett taps ex-Deloitte colleague David Gatt to join Omnicom Oceania

Omnicom Oceania has appointed David Gatt as Managing Director, Marketing Operations & Ecosystem Design, in a newly created role to help brands adapt to an AI-driven marketing landscape.

Based in Melbourne, Gatt will operate across the region, focusing on redesigning how marketing, data and technology integrate to deliver more connected and scalable growth.

New role responsibilities

The role comes as brands increasingly rethink how agency, data, and technology capabilities converge, shifting away from siloed execution toward integrated, end-to-end marketing systems.

Gatt’s remit will focus on helping clients move from fragmented execution to unified operating models that enable faster, more accountable outcomes.

Gatt will work across Omnicom’s broader ecosystem, including OMNI, alongside advisory capabilities from Credera and The Loom, as well as the group’s wider data, technology and agency expertise.

Gatt's past experiences

Gatt joins from Deloitte, where he led marketing transformation across sectors including telco, retail and financial services.

He brings more than 15 years’ experience, specialising in marketing automation, operating model design and translating technology capability into commercial outcomes.

CEO Nick Garrett comments

CEO Nick Garrett said the appointment reflects a shift in client priorities.

“The vast majority of conversations we’re having with clients right now and what we’re seeing in new business, is about operating models and a broader need for marketing transformation capability, not just marketing execution,” he said.

“It’s no longer just about how we evolve our business around clients, but how we help redesign theirs.”

Having worked closely with Gatt during his time at Deloitte as CMO, Nick Garrett said he had no doubt about the commercial impact Gatt brings.

“He is as talented as he is nice and will be a huge asset to our clients’ businesses. There are very few people in the Australian market with the depth of expertise in this space that Gatty brings, and that’s exactly why this role is so important for us.”

Gatt comments

Gatt said the opportunity lies in rethinking how AI is applied within marketing systems.

“The pressure on brands to unlock value from AI has never been greater, but most are using it to go faster down the same road,” he said.

The work I’m most excited about is helping brands ask whether they should be on that road at all and designing something better. Omnicom has everything needed to do that at real scale".
