Where can I watch Magical Land of Oz in United States?

A blue chip, continent-wide series ranging from Australia's highest snow peaks to the depths of the frigid and wild southern seas; from its last populations of wild numbats to its largest diorama of giant cuttlefish. It's a land of diverse beauty, that delights and surprises. The series both entertains and deepens our understanding of how the natural world is made up of not just unique species, but distinct individuals, whose lives are far from predictable.
