A candlelight vigil was held at the weekend to remember Mason Szanto.
Local 18-year-old Mr Szanto's body was found last week in the Flinders Ranges, after he had been missing for two weeks.
The event was on the Port Augusta foreshore, with family members and loved ones present.
Speeches were made in honour of Mr Szanto, remembered as "Forever 18".
A Go Fund Me webpage has been set up by the family, with the aim of raising $20,000. At time of print $8,320 had been raised.
His older sister Emily Szanto said the money would be used to help the family prepare for the funeral through this difficult time.
"We never planned for something like this to happen," she said.
"We needed some help.
"We will be using the funds to help out with his funeral.
"We are waiting for the autopsy to come back before we start making plans for the funeral."
Ms Szanto was unable to attend the vigil over the weekend due to being sick, but was represented by her aunt and two younger siblings.
"The family was touched by the effort people went through," she said.
"We still have not wrapped our head around it, but we are all coping at this stage.
"We have been really appreciative of everyone that has been helping.
"And on behalf of my family thank you to everyone that tried to help find my brother."
The family wished to convey their thanks to the Port Augusta City Council, local police, Pika Wiya Health Service Aboriginal Corporation, The Reject Shop Port Augusta, Interflora, Umeewarra Aboriginal Media 89.1fm and Ashawariya Designs for their support, along with community members Maybelline Shaw, Andy Shaw, Charlene Woods, Caitlin Swan, Candice Swan, MP Dan van Holst Pellekaan, Adele Marshall, Lisa Marshall Humphries, Jeanette, Rachel and Tanya.
