The tangled branches and gloomy undergrowth of Australia's forests provide the perfect hideouts and shadows in which to lie in wait. Secret lairs in which to launch a lethal ambush, a predators paradise. These are the case-files of Australia's notorious forest killers.

From tangled mangroves, and raging rivers, to dark waterholes and vast floodplains, Australia's waterways are complex, competitive, deadly. The riverbeds are battlefields where the vicious thrive. The marshy grasses are alleyways from where the cunning strike. A web of organized crime winds through Australia's deadly wetlands.

The Australian desert, a dry and desolate wasteland, hell on earth. In these parts only the toughest survive. Heat and dehydration kill indiscriminately and the wild life is armed and dangerous. Out there it's everyone for themselves.

Australia, a tropical paradise, but these pristine waters conceal sinister undercurrents. The oceans surrounding this island continent are home to some of the deadliest creatures known to man. Marine assassins that strike from the shadows or wield biological weapons that kill with terrifying efficiency, curiously intriguing, exquisitely beautiful and exceptionally lethal.
