Instead he wore yellow and sat in the middle of a Riverina park as he cried and hugged the hundreds of people who knew and loved his fiancee, Stephanie Scott.

The body of the popular school teacher was recovered from bushland north of Griffith on Friday, five days after she was allegedly killed by cleaner Vincent Stanford.

Ms Scott's parents, brothers and sisters were meant to have been celebrating at her wedding reception this afternoon. Instead, they joined the whole town of Leeton at a memorial picnic to honour their daughter and sister.

The man who helped find Ms Scott's body knelt down before her fiance on Saturday afternoon and offered his condolences.

Griffith police commander Detective Superintendent Michael Rowan appeared shaken by the killing that has rocked the small community.

Only hours earlier, he had spoken of how police trail bike riders discovered Ms Scott's remains in Cocoparra National Park, where her alleged killer regularly camped.

Ms Scott's father, Bob, somehow managed to muster a smile as he spoke to many of his daughter's students from Leeton High School.

Close to a thousand people have congregated in Mountford Park, where almost every tree is wrapped in yellow balloons.

Mr Leeson-Woolley walked around the park with his hands on his head, hugging many friends and wiping his tears on their shoulders.

All the local residents have worn yellow and have yellow ribbons attached to their wrists and hair.

Every now and again children let single balloons into the sky.

Police, firefighters and volunteers who have spent the past week searching for Ms Scott have also rallied around the family.

Earlier on Saturday, Stephanie's sister Kim shared the poetic wedding speech she had intended to read at the couple's reception, which was to have been held at a Eugowra golf course.

"They make each other smile, they can fill a room with love," she wrote.

"Joking and laughing, they fit each other like a glove.

"You're beautiful people, when you stand alone.

"Together you're strong, you set the tone."

As the family shared memories of the bright and bubbly teacher, her remains were being taken to Glebe Morgue in Sydney, where an autopsy will be carried out.
