But his memory was in the minds of many at the weekend, which saw the first Wear a Ribbon for Terry Day.

Terry's brother Daryl Floyd said the occasion - held on the anniversary of Terry's disappearance, June 28 - aimed to start conversations and raise awareness of what happened to Terry.

Sharing Terry's story, Mr Floyd said, would hopefully help keep other children safe.

Terry was last seen near Avoca on the afternoon of June 28, 1975.

A coroner determined in 2001 that Terry was murdered, but his body has not been found and no one has been charged in relation to his disappearance.

Tragically, Terry and Daryl's mother Dorothy died 12 years to the day after her son went missing, never knowing what happened to her child.

Mr Floyd said Wear a Ribbon for Terry Day was also about remembering his mother.

The day was an initiative of the Terry Floyd Foundation, an organisation Mr Floyd founded in the hopes of helping children.

Terry was unable to live out his dreams, Mr Floyd said, but he hoped other children would be able to live out theirs.

The foundation has provided scholarships to students in schools in central and north-eastern Victoria who stand up to bullying.

It has also helped rebuild Clifton Creek Primary School in East Gippsland, which was destroyed in the summer bushfires.

Recently the foundation kicked off a program through which schools 'adopt' an animal through Halls Gap Zoo and learn about it, with the intention of sending participating school students on an excursion to the zoo later this year.

Mr Floyd said there were also plans to deliver a workshop on decision-making for older teenagers.

Victoria Police confirmed the investigation into Terry's disappearance remained open and a $1 million reward for information was still available.

Anyone with information on Terry's disappearance should contact Crime Stoppers on 1800 333 000.

For 10 years, Mr Floyd has been searching a disused mine near Avoca where he believes Terry's body might be, and has uncovered fragments of clothing, a shoe and a silver chain, which match the clothing Terry was wearing the day he disappeared.

Reiterating the words of retired homicide detective Ron Iddles, Mr Floyd said a 12-year-old boy should not disappear from the side of the road without answers.

The Terry Floyd Foundation is looking for sponsors as it expands its work with children.
