“I have seen Tasmanian devils battle over a carcass. I have seen lionesses crowding a kill, dingoes on the trail of a feral piglet, and adult croc thrashing its prey to pieces. But never, in all the animal world, have I witnessed anything to match the casual cruelty of the human being.”

“Crocodiles are easy,' Steve said. 'They try to kill and eat you. People are harder. Sometimes they pretend to be your friend first.”

“It is a gift when someone can challenge you and open your mind to new ideas.”

“This time it is not a simple, understandable war, within the same culture. This time it is an assault of the animal world upon the house of the human being. I don’t know what you saw in Africa and Italy, but I know what I saw in Russia and Poland. We made a cemetery a thousand miles long and a thousand miles wide. Men, women, children, Poles, Russians, Jews, it made no difference. It could not be compared to any human action. It could be compared to a weasel in a henhouse. It was as though we felt that if we left anything alive in the East, it would one day bear witness against us and condemn us. And, now, we have made the final mistake. We are losing the war”

“There are too many books I haven't read, too many places I haven't seen, too many memories I haven't kept long enough”

“I never drink while I'm working, but after a few glasses I get ideas that would never have occurred to me dead sober.”

“I have no fear of losing my life - if I have to save a koala or a crocodile or a kangaroo or a snake, mate, I will save it.”
