Deveny has written for events such as the Logie Awards and the Australian Recording Industry Association (ARIA) Music Awards, and co-wrote the 2005 Australian Film Institute (AFI) Awards with Russell Crowe.
From 2001 to 2010, Deveny was a regular columnist for The Age newspaper, published in Victoria. In March 2009 she conducted a one-woman strike as a protest against the newspaper after her wages were reduced as part of an organisational restructure. Deveney's column was then removed from the newspaper after the writer/comedian caused controversy with Twitter posts that were in relation to the 2010 Logies awards ceremony.
In a radio interview following her sacking, Deveny claimed that her employers did not understand the nature of new media and how it is used. On 18 March 2009, during an ABC 774 radio interview between Jon Faine and the editor of The Age Paul Ramadge, angry supporters ambushed the show calling for Deveny's return as a regular columnist;
In June 2012, after Ramadge resigned following the announcement of a company restructure, Deveny wrote the following comment on Twitter: "I wish him arse cancer." Deveny has been named in The Age newspaper's "Top 100 Most Influential Melburnians" list.
Deveny is the author of Rank and Smelly (1997), Babies, Bellies and Blundstones (1999), Our New Baby (2005) and The Happiness Show (2012). Deveny's newspaper column writing has been published by Black Inc. in several collections: It's Not My Fault They Print Them (2007) and Say When (2008) and Free To A Good Home (2009).
The 2009 Festival of Dangerous Ideas, held at the Sydney Opera House, featured Deveny in a live debate with Cardinal George Pell, the Roman Catholic Archbishop of Sydney. In April of the same year, Deveny returned to stand-up comedy in the Melbourne International Comedy Festival with the show Mother of The Year.
Deveny appeared with Daniel Burt at the Butterfly Club venue in "An Evening Of Insight And Filth"—due to a high level of popularity, the show was extended by six shows. Deveny then appeared with Richard Dawkins, Peter Singer, Phillip Adams and PZ Myers at the 2010 Global Atheist Convention in Melbourne, Australia. Also in 2010, Deveny appeared in a one-woman show, entitled God Is Bullshit, That's The Good News, as part of the 2010 Melbourne Comedy Festival.
Deveny has also regularly acted as a substitute broadcaster on Australian radio station 774 ABC Melbourne.
In April 2010 Deveny caused controversy by posting comments on Twitter, such as "Anzac Day. Men only enlisted to fight for the money, for the adventure or because they were racist." and "An Australian Flag in your front yard tells everyone you're only a couple of Bundy and Cokes away from lynching a wog, slope or Arab."
In May 2010 a similar controversy arose when Deveny posted a number of Twitter comments during the Logies Awards ceremony. Deveny's comments caused controversy as they were in relation to public figures, such as the then 11-year-old Bindi Irwin ("I do so hope Bindi Irwin gets laid"); Rove McManus and wife Tasma Walton ("Rove and Tasma look so cute ... hope she doesn't die, too"—Rove's first wife Belinda Emmett died after being diagnosed with breast cancer). The Age fired Deveny two days after the event and a "Twitter ban" was consequently enforced during the 2011 Logies Awards event.
Deveny is a self-proclaimed atheist and, along with one of her three sons, is also dyslexic.Rank and Smelly, South Melbourne: Addison Wesley Longman Australia, 1997
