Australia's Deadliest

Deadly Playground (1x11)

:

Lisa suddenly becomes a snack of a massive Great White shark. With deep gashes to her face and her arm almost completely severed, her friends race to save her life. After Andrew is bitten by a snake, he is sure that it was nonvenomous, so he ignores it. He didn't know that the deadly venom of a brown snake coursing through his veins could kill him. And Ryan is bitten by a jumping jack ant and soon his parents rush him to the hospital, recognizing the signs of anaphylactic shock. Is it too late?
