How to protect yourself from these dangerous animals?
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.
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.
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.
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.

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?
Best wishes,
Li Haidi

Dear Haidi,
Thanks for your email. How wonderful it is that you are going to Australia.
I think you’ll have a great time on the camping trip and you’ll get to see native animals in their natural setting. Also you’ll make some good friends on the trip, which is much more difficult while staying in a hotel in the city.
Sample Writing
Don’t worry about the dangerous creatures. They are not as dangerous as some people think and anyway you’ll be with an experienced tour guide who will keep you safe. Just do everything the guide says and you’ll have a safe and enjoyable time.
Do write again when you get back and tell me all about your trip.
Your friend,
John
Dear Haidi,
Aren’t you lucky going all the way to Australia? I’m sure whatever you do, you’ll have a good time.
Personally, I would rather visit Sydney. I’m not very fond of sleeping in tents and I like to have my own nice, clean bathroom. Also there are mosquitoes in the National Park and I always suffer from mosquito bites.
Sydney is a very nice city and the weather is usually good. There are all sorts of interesting places to see, like the Sydney Opera House and the harbor bridge, and there are lots of wildlife parks you can visit to see native animals. Plus there are lots of great shops and restaurants in Sydney and the nightlife is pretty good too.
I think you would have a good time whichever holiday you went on.
You’re more adventurous than me so you would probably enjoy camping. Don’t worry about the dangerous creatures --- you’ll be quite safe on an organized tour.
Have a good time wherever you go and write back and tell me about it. Love, Murray
