Marnie has been in radio for the last 18 years starting her career in Brisbane at B105 in promotions.
After learning the panel and after much pleading to her boss she landed the midnight to dawn shift at B105 and then on to late nights (7pm til 12am). Marnie spent two years after that as the female breakfast host on Mix 106.5 in Townsville.
Upon returning to Brisbane she took the 9am-2pm slot on 97.3FM. After 6 months was promoted to the Breakfast show and spent four years hosting the Marnie T, Terry & Mark show. After doing a floating role for Brisbane, Melbourne Sydney and a night show in Adelaide, Marnie moved to mornings on Mix 106.5 in Sydney for two years and was also the host of the nationally syndicated Sunday lifestyle show Body & Soul in conjunction with News LTD, heard in Sydney, Melbourne, Brisbane and Adelaide.
