Going down the Holly Valance route, it would seem:
The Sunday Herald Sun reports that Stephanie McIntosh (Sky Mangel) has signed an international, five-album music deal with Universal Music. Although no other details have been released, it is apparently hoped that she will have a single out by mid-year, and that the deal will see her tackle markets in the UK, Australia and North America. Meanwhile, she reportedly has no plans to leave her Neighbours role and become a full-time singer, with current negotitations looking at her extending her existing contract by another year.
