A massive land and water search for an 11-year-old girl missing from her eastern suburbs home was still underway on Sunday evening, more than 24 hours after her sudden disappearance.

Up to a thousand members of the Bondi and Jewish communities combed the local area in search of the school student on Sunday night.

"Theres a sense of very clear purpose to help bring this nightmare for this family to an end," said Jeremy Spinak, the President of the NSW Jewish board of deputies.



Police, NSW SES and volunteers also undertook an extensive search of Centennial park.
