During her time at 702 Sydney first presenting 'Breakfast', Catterns temporarily displaced prominent Australian radio broadcaster Alan Jones in 2004 to achieve number one in the listener survey ratings. Catterns has also held broadcasting roles at Australian commercial radio stations 2SM and Vega 95.3 in Sydney, 2UE and at WKYS in Washington DC. Her popularity as a radio broadcaster is often attributed to her "perfectly measured combination of intellect and personality", her listening and interviewing skills, and a voice described as being "smooth as chocolate" ("The Sydney Morning Herald") or "as if her vocal cords have been marinated overnight in plum brandy and golden syrup" ("Elle" Magazine).
