SYDNEY, 9 April 2026 – Omnicom Oceania has appointed two senior leaders to its Executive Leadership Team as it continues to evolve its model and strengthen how it delivers for clients.
Kim Hamilton has been promoted to Chief Marketing and Communications Officer, Omnicom Oceania, expanding her remit from Chief Marketing Officer, Omnicom Media Australia and stepping into a broader enterprise leadership role across the region.
Paige Prettyman has been appointed Chief of Staff, Omnicom Oceania, a newly created role supporting executive alignment and delivery across the business.
Hamilton steps into the role after establishing Omnicom Media Australia’s first centralised marketing and growth function. In her expanded remit, she will lead enterprise brand, profile and communications across Omnicom Oceania, driving market positioning and strategic partnerships, while continuing to play a key role within Omnicom Media.
Prettyman joins from Deloitte Digital, where she was Managing Director. She previously held senior leadership roles at Special Group Melbourne and Clemenger BBDO.
Nick Garrett said:
“We talk a lot about helping our clients navigate transformation and elevating the role of marketing at an executive level. What’s important is that we’re doing the same ourselves.
These appointments are about putting that into practice, building a business that is more connected, more focused on the customer, and set up to deliver real commercial impact.
Kim has proven herself as a leader who delivers, driving growth, shaping our strategic direction and playing a central role in the transformation of our business and the value we create for clients.”
Hamilton added:
“I’m genuinely energised by the vision and transformation that Nick, KK and the broader team are building together at Omnicom Oceania. We are building something genuinely different, more connected, more capable and better set up to help our clients navigate increasing complexity. Now it’s about bringing that to life in market and for our people – simple, clear and with impact.”
Garrett added:
“Paige brings a strong mix of creative, agency and consulting experience, along with a clear understanding of what clients are looking for from partners today.
This role is about making sure we stay aligned and focused as we scale, and that strategy turns into action.
Paige has the credibility and judgement to operate at this level, along with the experience and capability to get things done.”
Prettyman said:
“What’s really compelling about Omnicom Oceania is the opportunity to bring together creativity, media and advisory in a genuinely connected way and the impact that can have for clients.
My time in leadership positions across both advertising agencies and consultancies has shown me how powerful that can be when it’s done well.
I’m looking forward to working closely with Nick and the leadership team to ensure that translates into clear priorities, strong alignment and consistent delivery across the business.”
