[1][2] Born in Sydney, Cordeaux began his career in radio during 1962, at the age of 16, when he became an errand boy for John Laws at 2GB.
[10] Cordeaux was sacked by FIVEaa in March 2021 following on-air comments about alleged rape victim Brittany Higgins.
[16] In 1999, Cordeaux was implicated in the cash for comment affair when ABC Television's Media Watch program aired allegations by former 5AD news director Neil Wiese.
[18] In response, Cordeaux said Wiese was a former employee who had been terminated for dishonesty, and who had orchestrated a "ten-year campaign of venom and vindictiveness", and who had since been employed by the ABC.
[18] However, following the Australian Broadcasting Authority's investigation, Cordeaux was found to have substantially breached the industry's code of practice.
[20] The ABC found Cordeaux's undisclosed personal sponsorship deals with the likes of Adelaide Casino, Network Ten, GIO and Optus had influenced the content on his programs.
[22] He later complained about not knowing about the scheduling of the court proceedings, and said he had expected someone from South Australia Police to inform him when he was due to appear.
[22] Cordeaux faced a similar drink driving charge in 2005, after he allegedly recorded a blood alcohol reading of 0.085 during a random breath test in late 2004.
[30] He won three Gold Medals from the International Radio Festival of New York in 1987, 1988 and 1989 for Best Talk Show Host in the World.
[5] Cordeaux became a Member of the Order of Australia (AM) on 12 June 2006, in recognition for his service to the broadcasting industry, and for his support of various charitable organisations.
