Australia Post moved its media account to Accenture Song from 1 June 2026 after a competitive pitch, ending a seven-year run with incumbent Wavemaker. The deciding factors were data, technology and AI-led media capability.
The pitch was not won on media buying. It was won on data and technology. That should tell agencies where the ground is moving.
Australia Post has pulled its media account out of a traditional agency and handed it to a consultancy. Accenture Song became media agency of record from 1 June 2026 after a competitive pitch, taking strategy, planning, activation and performance. Wavemaker, the incumbent of seven years, lost it.
Read what won the pitch. Australia Post said the deciding factors were data, technology and AI-led media capability. Accenture Song already runs the creative through its Droga5 arm, so the consultancy now owns both ends of the work.
This is the same defection story playing out across the market. Accenture Song built its media division in 2024 when Melissa Fein, Sam Geer and Chris Colter left Initiative to start it. Two years later it is taking national accounts off the holding companies.
Why it matters
A seven-year incumbent losing a marquee account is not a one-off. It is a signal about what large advertisers now value. They are buying the ability to connect data, technology and media into one system, and they increasingly believe consultancies do that better than media agencies built for a different era.
How long Wavemaker held the Australia Post media account before losing it to a consultancy
For Australian agencies the message is blunt. Media buying on its own is not the moat it was. The work is moving toward whoever can wire the data and the technology together and prove performance.
What to do about it
The holding companies built the last era of media. The consultancies are pitching the next one. Australia Post just told you which way it leans.
