How to protect yourself from these dangerous animals?

Spiders are usually found in dark, dry places, under stones or amongst rubbish. The poison is slow acting so there is plenty of time to get to the hospital.

Many beaches have shark nets to keep sharks away from swimmers. In hot weather, small planes fly along the coast looking out for sharks. If one is spotted an alarm is sounded to warn people to get out of the water.

When jellyfish are close to the beach, you usually find a few dead ones on the beach. Vinegar can help relieve the sting of jellyfish. If a person has trouble breathing or becomes unconscious, they should be taken to hospital immediately.

Saltwater crocodiles are found a long way from settlements only in the far north of Australia near rivers and waterholes. There are usually signs to warn people that crocodiles are in the area. Crocodiles stay hidden in the water or on the land close to water.

Dear _______,

I am thinking of going on a camping trip in the Northern Territory. The trip is organized by a well-known tourist company with a good reputation.

We will be camping some of the time in Darwin and some of the time in Kakadu National Park. It sounds like lots of fun and I would see lots of wildlife, but I’ve heard so much about the dangerous creatures in Australia that I’m a bit scared about going out of the city.

Perhaps I’d be better staying in Sydney. I know there are lots of interesting things to see there too. What do you think I should do?
