Barry McKenzie (full name: Barrington Bradman Bing McKenzie) is a fictional character created by the Australian comedian Barry Humphries (but suggested by Peter Cook) for a comic strip, written by Humphries and drawn by New Zealand artist Nicholas Garland in 1964, in the British satirical magazine Private Eye.
The comic strip about a randy, boozy Australian rampaging through Swinging London was very popular, but Eye editor Richard Ingrams eventually dropped it on account of Humphries’ drinking and missing deadlines (Ingrams gave up alcohol in the Sixties, as did Humphries in the seventies). Ingrams said that Humphries was at that stage a serious alcoholic. 
The Private Eye comic strips were compiled into two books, The Wonderful World of Barry McKenzie (1968), in which McKenzie travels to Britain to claim an inheritance, and later, Bazza pulls it off! (1971). The books were published in London, but were banned in Australia with the Minister for Customs and Excise stating that they "relied on indecency for its humour".
In 1972, the film The Adventures of Barry McKenzie was released, based on the first published book. In 1974, a sequel, Barry McKenzie Holds His Own, was made. The films starred Australian singer Barry Crocker as McKenzie, and chronicled the character's adventures in Britain and France respectively. In the films, McKenzie is the nephew of another of Humphries' characters, Edna Everage. Despite the banning of The Wonderful World of Barry McKenzie in Australia, the films received considerable support from the Australian government of John Gorton, becoming the first to receive funding from the Australian Film Development Commission. Later Prime Minister Gough Whitlam even made an appearance in Barry McKenzie Holds His Own, where he granted a damehood to McKenzie's aunt, Edna Everage.
The character was a parody of the boorish Australian overseas, particularly those residing in Britain – ignorant, loud, crude, drunk and punchy – although McKenzie also proved popular with Australians because he embodied some of their positive characteristics: he was friendly, forthright and straightforward with his British hosts, who themselves were often portrayed as stereotypes of pompous, arrogant, devious colonialists.
McKenzie frequently employs euphemisms for bodily functions or sexual allusions, one of the most well-known being "technicolour yawn" (vomiting). The film popularised several Australian euphemisms and slang terms which are still used today in the Australian vernacular (such as "point Percy at the porcelain", "sink the sausage" and "flash the nasty"). Some of the sayings were invented by Humphries, while other terms were borrowed from existing Australian slang such as "chunder" and "up shit creek" (adopted by the Australian poetry magazine Shit Creek Review).
