The 11-year-old was found in Surry Hills about 10.30am on Monday.

Her parents Adam and Anne Levy left their home to go and pick their daughter up with police.

"We are just so thrilled," her mother said.

"She said she was in good spirits and she just wants to come home.

"I don't think this would have happened so fast if it weren't for all the people out there."

Anne posted a message to Facebook saying: "She's been found! Going to fetch her now. Thank you everyone one and all!"

Hundreds of messages of relief and thanks were posted to a Facebook page that had been set up to find Michelle just minutes after the news broke that she had been found.

"Best news all morning!!!!," wrote one person.

"I can't stop crying I am so relieved," said another.

"It's heartwarming to know that even in a world full of hate that there is still good people in this world willing to help without asking for anything in return. So happy she's found safe xx," wrote another.

Michelle left her home in Glenayr Avenue, North Bondi, after a family argument about 6.30pm on Saturday.

Her distraught extended family and their friends spent Saturday night scouring the streets before calling in the police. She was spotted on security footage at Bondi Junction on Saturday and Randwick on Sunday.

By Sunday morning, a police hunt was well under way with officers from the Police Rescue Team and SES personnel searching the area, including the eastern beaches clifftops and waterways.

Up to 1000 members of the Bondi and Jewish communities combed the eastern suburbs on Sunday in search of the girl, whom friends have described as intelligent, shy, and "gentle as a butterfly".

Many were planning to reconvene in Bondi on Monday morning to plan the next phase of the search.
