Karl O’Callaghan
Karl O’Callaghan is the former Police Commissioner for Western Australia, a position which he held from 2004 to 2017. He is the longest serving post-war West Australian Police Commissioner and was formerly a career police officer having served for more than 43 years. He has been awarded the Australian Police Medal and is a Rotary International Paul Harris Fellow, awarded for outstanding community service. He is also the first serving police officer in Western Australia ever to be award a PhD and in 1997 was made a Churchill Fellow.
Karl has overseen significant reform and cultural change within the Western Australia Police Service having been appointed by Government to oversee the implementation of reforms. His significant work on police culture not only resulted in the ‘modernisation’ of the WA Police and the ‘softening’ of old hierarchical structures but also resulted in a greater gender balance in the most influential management levels in the Force.
During his time as Police Commissioner he was arguably the most well known and most listened to public sector figure gaining respect for his practical and common-sense approach. He is credited with being one of the only Police Commissioners in Australia to regularly work on the street with front line officers.
Karl is still very much in demand by the media for opinion-based commentary on a range of issues affecting the community and regularly, both writes opinion pieces for print media and works in radio. In recent times he has developed quite a high profile as an announcer and DJ on one of Perth’s premier community radio stations and his knowledge of the music industry furnish many amusing and informative anecdotes for his listeners.
