Inland Kimberley is now so stiflingly hot, everything and everyone moves with caution - with the exception of gold diggers Honest John and Steve. The region's remaining waterholes are packed with animals, forced dangerously close. Windjana Gorge is a prime example: a pristine oasis where brave humans wade into croc-infested water all in the name of science. The coast is also a place to congregate. Thousands of shorebirds arrive from the world's longest single migration, only to be blasted with nets by crafty bird lovers. The humidity builds and finally, the skies explode with thunder and rain. Nyul Nyul ranger Albert Wiggan sings a welcome to the life it brings and arrival of a new season in his ancient land.

It might be the dry season but there's no rest in the outback: There are turtle eggs to be laid, saltwater crocodiles to dodge and young birds on maiden flights. Cattle must be mustered from the far corners of vast cattle properties and, when that is done, rodeos slam into action. More quietly, archaeologists are led through remote wilderness by traditional owners, revealing breathtaking galleries of ancient rock art. Out at sea, elite athletes dive the ocean depths in the name of the world's most spectacular pearl, risking dangerous encounters with curious giants. Meanwhile, mother to marsupials Mandy Watson sets her babies free.

The Kimberley region in North West Australia boasts some of the most spectacular wilderness, and tough characters, in existence. We meet the humans and the creatures, who – as the wet season comes to an end - begin their adventures across this diverse and surprising landscape. From the tiny orphaned joeys to the majestic osprey, survival takes guts (and sometimes even the huge heart of human carers). It's a land where humans and animals live in dangerous, and exquisite, proximity.
