About
A mid-tier full-service media agency in Australia with a distinctive joint-venture structure, operating independently from the broader Omnicom Hearts United rebrand that affected the rest of the Mediahub global network.
Mediahub Australia is the Australian arm of the Mediahub media agency, operated as a joint venture between Omnicom (which inherited Interpublic Group's majority stake when it acquired IPG in November 2025) and the independent Attivo Group, which bought a minority share of Mediahub Worldwide Asia-Pacific from IPG in June 2021. It is led by Sue Squillace, CEO of Mediahub ANZ, with offices in Sydney and Perth. When Omnicom Media combined Mediahub and Hearts & Science into Hearts United in August 2026, Australia was the exception: because of the joint-venture ownership, Mediahub Australia continues to operate as a separate agency, while Hearts & Science Australia took the Hearts United name. Ownership percentages have not been disclosed.
