Helen Smarts sister, first seen when Judy Bryant helps Helen to try to get Sharon away from a sinister sub-Moonie cult led by Alpha Centauri. The members of the cult have to submit to a severe test of loyalty, such as being forced to answer to preposterous cult names: Sharon's is Sister Peace Bird. Helen and Judy have Sharon kidnapped and taken to the attic at Driscoll House to be "deprogrammed", but Sharon accidentally stabs the de-programmer Colin Burton in the stomach with a cheese knife and kills him. She is brought to Wentworth charged with malicious wounding but she blames Helen for her problems and accuses her of wanting to get hold of her money. At Sharon's trial, Judy and Helen give evidence in her favour: Sharon is found guilty and sentenced to 3 year's probation (388). Played by Liddy Clarke
