Mojo was an Australian advertising agency formed in Sydney by Alan Morris ("Mo") and Allan Johnston ("Jo") in 1979. Its lineage can today be directly traced to Publicis Mojo, an Australian subsidiary of the French multinational advertising and communications company holding Publicis Groupe.
Johnston, initially from Adelaide and Morris from Sydney teamed up in the mid 70s at Sydney agency Hertz Walpole. Johnston had been employed there since 1968 and Morris was freelancing. Johnston and Morris had immediate success together working on campaigns for Hertz Walpole clients Meadow Lea margarine ("You oughta be congratulated") and Tooheys beer ("How do you feel?") and they left the agency but continued to work on such clients as they grew their consultancy. In 1979 their creative consultancy became a full-service advertising agency and Meadow Lea and Tooheys amongst other clients, signed with the new shop.
During the 1980s, MoJo was the hottest creative agency in Sydney and Mo and Jo had success jointly authoring World Series Cricket's "C'mon Aussie C'mon" and later the Australian Tourism Commission's spot with Paul Hogan's instruction to "put another shrimp on the barbie".
The MoJo approach to TV advertisements used a colloquial and irreverent style, often with a catchy jingle to simple accompaniment and frequently sung in Jo's own "gravelly" voice. Contrasting against the clipped and British-imitating style of voice presenters on Australian TV up till that point, Mojo ads highlighted Australian idiom and accent. Ads such as “I’m as Australian as Ampol”, “Hit ‘em with the Old Pea Beau” (insectide), “Everybody loves Speedo”, “I Can Feel a Fourex Coming on”, “Every Amco tells a Story” (for Amco jeans) all came out of the Mojo agency in the 1980s.

The merger was unsuccessful and in 1992 Chiat/Day sold off Mojo to Foote, Cone & Belding. The Mojo lineage can be directly traced today to the Brisbane, Sydney and Melbourne agencies Publicis Mojo, Australian subsidiaries of the French multinational advertising and communications company holding Publicis Groupe.
