The remaining family of a missing Sydney model turned prostitute has welcomed a $1million reward for information about her disappearance 26 years ago.
Revelle Balmain, 22, was last seen on November 5, 1994, at Kingsford, in the city's eastern suburbs and is presumed to have been murdered.
Ms Balmain's half-sister, Suellen Simpson, said her sibling's disappearance had caused immeasurable grief to her family for a quarter of a century.
'For many years, our family worked tirelessly to find out what happened to my sister - but sadly both our mother and Revelle's father, Ivor, passed away without ever knowing what happened to their little girl,' Ms Simpson said.
