Steve Lucas (Joss McWilliam) is a nineteen year old who is filled with the burning resentment of being forced to live in his brother's shadow. His brother Adam (Colin Friels), is burdened by his father's desire for glory, and must win The Coolangatta Gold Tri-Aquathon. Set on the beautiful beaches of Queensland's Gold Coast, it is the greatest endurance test of them all: a marathon involving a 20 kilometre beach run, 6 kilometre swim and a 17 kilometre surf ski from Surfers Paradise along the golden arc of beach to Coolangatta and back to the start. The Coolangatta Gold is a story of human endeavour and endurance against overwhelming odds.
