Swinging between drought and deluge, Australia’s tropical Top End is literally teeming with life – and death. When prey is abundant, the Nightmares of the North are on the prowl. Nowhere is safe – Saltwater Crocodiles terrorise river systems ambushing prey at the water’s edge. Toxic Box Jellyfish and the world’s most venomous fish, Stonefish, lay waste to many creatures in the estuaries, and Whitebellied Sea Eagles rain death from above. Ruthless monsters wreaking havoc in Australia’s tropical north.
