I have just received a letter from my brother , Tim. He is in Australia. He has been there for six mouths. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has lust bought an Australian car and has gone to Alice Springs , a small town in the centre of Australia. He will soon visit Darwin. From there , he will fly to Perth. My brother has never been abroad before , so he is finding this trip very exciting.
