The eleventh installment in the World Exploration Comic History series takes readers to Australia, the land of koalas and kangaroos. Through an engaging comic-style story, children can naturally and easily learn about Australia, while Tori's History Corner offers deeper insights into the country's background. Tori and Assistant Lee travel to Australia in place of Professor Ji, who is away on research, to receive a boomerang—an artifact of the Aboriginal people. But when the boomerang goes missing, they set off to find it among Australia's Indigenous communities. There, they discover that a character named Bongpal has stolen the boomerang, and using a map drawn by the tribal chief, they begin a race against time to recover it before he does. Following clues hidden within the boomerang's design, Tori travels across Australia, experiencing its natural beauty, history, and culture while coming to understand the spirit of its Indigenous people. As the secret of the boomerang unfolds, Tori discovers something even more precious than treasure in this exciting adventure.
