Enrolment of Indian students in Australia is expected to go down by about 21 per cent over safety worries. In its latest projection, Tourism Australia has said the recent spate of attacks on students will result in 4,000 fewer Indians coming to Australia to study next year. <br/><br/>Head of its forecasting committee, Bernard Salt said, this could lead to a loss of about 70 million US Dollars in revenue. He said the study is based on consideration of visa applications.<br/><br/>President of the Federation of Indian Students in Australia, Gautam Gupta, however said the slump would not be as severe as feared earlier after a spate of attacks on students of Indian origin up to June this year. He said, fears were that the slide could touch as high as 50 per cent. But it is going to be only 21 per cent.
