I have just received a letter from my brother, Tim. He is in Australia . He has been there for six months. 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 just bought an Australia car and has gone to Alice Springs, a small town in the center of Australia . He will soon visit Darwin. From there , he will fly to Perth . My brother has never been abroad before,so he is find this trip very exciting .
