Sister makes appeal for missing NSW woman

The sister of a woman missing on the NSW Central Coast is asking the public to help police find her sibling.

Foster woman Nardia Clark, 56, was last seen at her home on Little Street on July 4, where she left behind her wallet and bank cards.

Her family say her disappearance is out of character, and they will make a public plea with local police on Thursday for help find Ms Clark, who's about 155cm tall with a thin build and shoulder-length grey hair.
