Medibank CMO Geoff Ikin said the appointment reflects Medibank Group’s ambition to grow as a health company and continue evolving how it engages customers across its portfolio while ensuring media investment delivers stronger enterprise outcomes.
“As one of Australia’s largest health companies, we are focused on creating more relevant and personalised experiences for our customers across every interaction,”Ikin said.
“We felt a real cultural alignment between our teams from the outset. Accenture Song has a genuinely differentiated proposition in market that brings together outstanding talent, technology and strategic firepower, as well as the transformation capabilities needed to help us accelerate growth across the portfolio.
“Media plays an increasingly important role in how people discover, engage with and experience our brands. The partnership with Accenture Song will help us accelerate our ability to connect data, technology, creativity and customer insight in ways that improve effectiveness and deliver better outcomes for customers.
“We would also like acknowledge our long-standing relationship with Dentsu and thank them for their partnership and contribution over many years.

The new partnership will span media strategy, planning and buying across Medibank Group, and support the organisation’s continued investment in customer experience, effectiveness, technology enablement and marketing transformation.
Accenture Song managing director Sam Geer said: “When we imagined the kind of businesses we wanted to partner with in Australia, Medibank Group was right up there.

Accenture Song’s MD Chris Colter added: “Medibank Group plays an incredibly important role in Australian life and culture.
