A day after Gary Tweddle's body was retrieved from the Blue Mountains, his mother has described him as a perfect child who never received a bad school report.
In a post on Mr Tweddle's Facebook tribute page `Have you seen Gary Tweddle', Carol Streatfield remembers the day her son was born, a "perfect looking baby" with black hair and dark skin.
"I was so proud of you," Carol wrote.
"Gazy u never had bad school report. perfect child through all your years I never met one person who could falt you.
"Such a beautiful soul. Love you with every breath I take."
Carol, Mr Tweddle's father Gary and other family learned on Tuesday of the discovery of a body matching his description in the Blue Mountains, west of Sydney.
The body has been taken to Glebe morgue where it's going through a formal identification process, which could include a dental examination and DNA testing.
Police abseiled down Sublime Point at Leura to retrieve the body which was spotted on Monday afternoon by an ambulance rescue helicopter involved in a training exercise.
They did not formally identify the body but said they were confident it was that of Mr Tweddle, who disappeared from a work conference in the Blue Mountains on July 15.
The site is about 2km from where the 23-year-old computer salesman was last seen, before he went missing from the conference at the Fairmont Resort in Leura.
His partner Anika Haig, who has been heavily involved in the search since he disappeared in mid-July, was in the area with her mother and sister talking to police.
Earlier in the day, Ms Haig had written on her Facebook: "One thing I know for certain is that Gary will come home one day - his fight, determination and 'never give up' attitude that we all loved so much about him will guide him."
