He is to be replaced by Galaxy programming director for Manchester James Brownlow, who will report to director of broadcasting, Richard Park, and will be responsible for all programming output at Capital.
Following three years at the station, Jackson’s new role as group programme director at DMG will charge him with heading up programming for several stations, including Radio Nova, Classic Rock, FIVEaa, NovaNation and Koffee. Jackson will be based in Sydney.
Prior to Capital, Jackson was programme director at Absolute Radio’s previous incarnation, Virgin Radio.
Richard Park said: "We look forward to welcoming James to this senior role and to the team at Leicester Square in November. We are certain he will be a great asset to Capital as we continue to develop and grow the brand."
"We are of course sorry to lose Paul. He has been a programming giant at Capital over the years, and integral to its great success. We all wish him the best of luck in Australia in his new role at DMG."
Brownlow added: "This is an incredible opportunity – I’m extremely passionate about the Capital brand and look forward to working with its talented team to continue the station’s success."
