About the impact of these attacks on the influx of Indian students, Walters said: 'We have not experienced any dip in the number of enquiries from India. In fact, this year it has increased four times.'

He said that ten years back, only 10,000 Indian students were enrolled in Australia but last year this figure rose to 100,000.

'Punjab is certainly an important place for us as 40 per cent of these students are from this region,' Walters said.

Australian authorities formulated an 'International student strategy' July 2, which Walters said would help to improve the international students' experience through improved pre and post-arrival information and engagement with the ethnic and broader Australian community.

'We are also going to have a high-level round table meeting on Sep 15 and 16, involving international students,' he said

At the same time he admitted: 'However, we cannot guarantee the safety of all the tourists and students studying in Australia. In fact, no country can do so. It is an unfortunate thing but we cannot eradicate crime completely from this earth.'

In the wake of recent incidents, Australian government is also going to review its 'Education Services for Overseas Students' Act'.

'We would review that how actually this Act addresses the needs and problems of international students. We had reviewed it three years back but during this period the number of international students coming to Australia has dramatically increased,' said Tulip Chaudhary, from the Australian department of education and employment.

She added, 'We would start reviewing it by the end of July and it will continue till this year end.'
