Albury High School’s Cody Brinkworth was chosen for his centrifugal go-kart transmission design which exceeds the performance of a two-speed gear box, while being cheaper and simpler.

He said once he saw the mechanics finally working he felt he “had achieved something that I was told I could never do”.

Meanwhile, Trinity Anglican College’s Matilda Trebilcock created a pulley system which eliminated the need for people installing nesting boxes to climb an unstable ladder while carrying a heavy box and tools.
