Bodie's mother, Hayley Hamilton, earlier told the Herald they had just left their nearby home, heading to Discovery Park.
Bodie pushed the button at the crossing, before walking across when getting the green signal.
At the same time, De Costa was heading west along Discovery Dr and failed to see the red light and the pair crossing the road.
Bodie - who has made a full recovery - was hit and thrown several metres into the air before landing on the road.
De Costa's counsel, Glen Prentice, said he was remorseful for what happened and had no other bad driving history.
"It was a bad error of judgment on the defendant's part. He has to accept that the light was red, he went through the red light.
"Looking at the CCTV footage the young boy has run out on the road and it's just an unfortunate string of events that has led to what's happened."
De Costa could pay the victims $1000 initially and pay the rest off at $40 per week.
