The 2019 Red Bull 'Branched Out' tree climbing contest will be held in Kapunda on October 17 - 19, with a record number of entries already received.
About 150 competitors have signed up to swing, limb walk and jump to capture the lofty prizes and coveted titles.
Organisers Arboriculture Australia said the Kapunda event will be the largest international tree climbing event in the world.
"Red Bull Branched Out 2019 has the largest prize pool with $25,000 cash and $50,000 of prizes and kit..." Organisers said.
Spectators will be able to watch the tree climbers at Davidson Reserve Kapunda starting Thursday 17 October during practice, after which there will be a competition gear check and BBQ at the new Kapunda Town Square on Main Street.
The preliminaries will be held on Friday October 18, with an additional stand-alone event in the evening where climbers speed-compete ascending the 25-30 metre trees under lights.
Saturday October 19 is the main competition; where the climbers' skills and agility will be tested, using swings and branch walks to reach designated targets.
"Arboriculture Australia brings the free Red Bull Branched Out event to towns where the community has the opportunity to benefit economically from the event being hosted in their community," event organiser Craig Hallam said.
"Community groups are supporting the event with hospitality and other services.
"Activities will be there for children to learn about the care of trees and arboriculture as a career with local schools also being invited."
Professional tree climbers and supporters from 14 countries along with 50 event crew and volunteers will provide a welcome economic boost to the Light Council Region and the Barossa.
