End of era as DDB Sydney moves out of Ultimo into Clemenger BBDO’s Walsh Bay office

After more than 20 years DDB Sydney has vacated its Mountain Street, Ultimo office to move into Clemenger BBDO’s Walsh Bay office next week. CB understands the combined businesses will officially become Clemenger BBDO on January 1.

John Lam, Creative Partner at DDB Remedy, has shared a photo of the now-empty DDB building on Mountain Street in Ultimo with the simple note:

“Today we say farewell to the DDB name and to the offices in Mountain Street, Ultimo. Thanks for the memories.”

Former DDB Sydney CCO Ben Welsh, now based in regional Victoria, commented: “Crazy. So many great people, ideas and memories, good luck everyone.”

The farewell follows Omnicom’s announcement that it would merge DDB Australia with Clemenger BBDO to form a single national agency, bringing together two of Australia’s most storied creative brands under one banner.

According to the original announcement, the merged agency will operate across key offices in Sydney, Melbourne and Brisbane, with leadership drawn from both legacy brands. The strategic goal is to create a more cohesive national offering for clients, aligning creative, strategy and production under one unified structure while simplifying go‑to‑market delivery across Australia.
