Her big break came when she landed the role of Felicity 'Flick' Scully in Neighbours. Holly's first single was Kiss Kiss which was released in 2002 (based on Tarkan's hit single Simarik).
The video for Kiss Kiss was notable for the impression that she was dancing naked, with her nudity only concealed by strategically placed lighting. In fact she was dancing wearing flesh-coloured underwear, and the footage of her dancing was then digitally retouched to create the illusion.
Her debut album Footprints went on sale at the end of that year.
In 2002 she won the British GQ Award for "Woman of the Year".
