Police are appealing for public assistance to help locate missing child Chaz.
The 10-year-old boy was seen riding his motorcycle between 1pm and 5pm at a campground off Four Mile Beach Road in Jeparit.
Police and family have concerns for Chaz due to his age, and the length of time he has been missing.
Chaz is described as being approximately 130cm tall with blonde hair and is of slim build.
He was last seen wearing a grey jumper and red motorbike pants. Chaz is believed to be in possession of his helmet.
The motorcycle was located about 5pm approximately 3km from the campground.
Police, along with SES volunteers and the Air Wing, are searching the areas surrounding Lake Hindmarsh and Four Mile Beach.
Investigators have released an image of Chaz in the hope someone recognises him and can provide information on his current whereabouts.
Anyone who sights Chaz or with information is urged to contact Horsham Police Station on (03) 5382 9200.
