Australia's arid interior is a land of stark beauty. Stretching for over two million square miles, it's a vast mosaic of red sand dunes, mulga woodlands, dry flood plains, and spinifex grasslands. Occupying this land of extremes are hosts of desert nomads, water seekers, and ferocious carnivores. They come in a variety of shapes, sizes, and species but share one similarity: remarkable adaptations that have allowed them to survive, and even thrive in this world of boom or bust, which has been reshaped by colossal forces over millions of years.

Australia's arid outback covers 70% of the continent's terrain, but along the eastern coast is a whole other world of soaring peaks, towering cliffs, and lush forests: the Great Dividing Range. These mountains tell the story of how this ancient land came to be and how its unique species have evolved and adapted to survive. Shot from majestic heights and deep within its diverse worlds, we explore the range that both unites and divides Australia, and the Tasmanian devils, koalas, southern corroboree frogs, and other creatures who call it home.
