OMD Australia has unveiled a new leadership structure for its Brisbane office, as Managing Director Rob Swinton concludes his 20-year tenure with the Omnicom media agency.

Effective immediately, Alison Costello, who joined OMD in 2019, has been appointed to take the helm.

"I feel so fortunate to have worked with Rob for 15 of his 20 years at OMD. During this incredible tenure, Rob has led and grown our Brisbane business and team to become the powerhouse they are today," said co-CEO of OMD Australia, Laura Nice. She added that Swinton leaves OMD Brisbane as the leading agency in the Queensland market and that they look forward to honouring his achievements with a special send-off.

Costello, Swinton's successor, initially joined OMD as Head of Digital Brisbane in 2019. She was promoted to National Head of Digital in 2021 and later to Chief Transformation Officer in 2023. With over 18 years of experience and a proven track record of delivering long-term transformation for OMD's clients, Costello is well-positioned to take on the new role.

"Throughout conversations with Rob and looking to the bench strength of talent in Brisbane, we identified a new leadership structure to create what's next for this important OMD market," said Nice. She expressed excitement over Costello's appointment and the evolved focus on delivering business transformation for their clients as part of OMD's future-focused vision.

"I'm incredibly excited to build on the momentum within the OMD Brisbane office. The opportunity is not lost on me, and I look forward to continuing to set up our people, clients and media partners for success alongside the Brisbane leadership team," said Costello.

The new leadership structure in Brisbane will be supported by Kenny Stewart, who remains as Group Managing Director Queensland and Victoria, and Nathan Fraser, who transitions from Head of Group to Managing Partner.
