清洗傷口，讓傷者保持冷靜，並且就醫。

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

值得知道

小知識

Where cane toads arrived at Kakadu National Park, almost the entire population of this lizard was wiped out. Its numbers have been estimated to have dropped by as much as 97% within three years.1

Its eyesight is excellent, but it is night blind because its retinas have no rods, the cells used for night vision.1

The biggest threat to this lizard is the cane toad. Cane toads are poisonous to it, and it can eat the larger toads, which carry lethal doses of poison.1

The Australian name 'goanna' probably comes from 'iguana', because the first European settlers thought these lizards looked like the iguanas of South America.1
