ABC's Children's TV department is in the midst of a restructure, following the resignation of head of commissioning and development Carla de Jong.
Commissioning will now be separated into two areas: live action and animation.
Current vice president of programming and development at the UK's HIT Entertainment Chris Rose will take up the position of head of animation in May.
Rose has previously worked in acquisitions for BBC's Children and CBeebies. He has also served as exective producer on a number of animated series aimed at pre-schoolers, including HIT Entertainment's Mike the Knight, which he developed.
Commissioning and development editor Simon Hopkinson will oversee the live action children's TV department after three years commissioning drama and animation for ABC's children's channels under the direction of de Jong.
Both Rose and Hopkinson will report to ABC Children's controller Tim Brooke-Hunt.
De Jong will depart the ABC at the end of March and relocate to Toronto, where she will act a consultant for the development, financing and co-production of children's content.
