On a sweltering Australia Day in Brisbane, the worlds of three young people collide. Indigenous teen April, young Chinese woman Lan, and Sami - an Iranian-Australian teen - are desperate and on the run. As each of their stories unfold, farmer (Bryan Brown), Indigenous policewoman (Shari Sebbens) and homicide detective (Matthew Le Nevez) are also swept into a whirlpool of violence, racism and resentment. Provocative and illuminating, Australia Day offers a fascinating take on national identity and the cultural tension that lurks beneath the surface of modern Australian society.
