The third place result is the NSWIS rider's second podium of the season. In February he won his maiden World Cup victory in Feldberg, Germany.
After the event a happy Bolton commented.
"Had a crazy start to the day, had a big crash in training but luckily had Wennie here to help me out and work some miracle physio at the top."
"The first heat was shaky too, I was in second place and got passed by everyone after I made a mistake, and then went from fourth back to first."
"It's been a rollercoaster day, won the next round of 16, second in the semi-final, and then finished on the podium."
Also in action for Australia was Alex "Chumpy" Pullin, who finished 18th and Adam Lambert 25th.
The final World Cup standings reflect Bolton's breakthough season, with a personal best fifth place end of season ranking, easily surpassing his previous best of 20th in 2017.
Pullin finished the season in seventh, with Adam Lambert 15th.
