The university has refused to comment.

'The university has processes in place that ensure that any allegations that are made, that could constitute criminal conduct, are referred to the police,' the university's senior deputy vice-chancellor, John McCallum, was quoted as saying in a statement.

Australia's education sector is bracing itself for a possible downturn in international student demand following a series of attacks on Indian students over the past three months.

The sector has also been rocked with reports of students being exploited and a migration and education scam that was unearthed. Nearly 100,000 Indian students are enrolled in various courses in Australia.

International student representatives Thursday said there was no evidence that solicitation of bribes was a problem at Australian universities, given a lack of complaints.

Gautam Gupta, of the Federation of Indian Students of Australia, said while he had heard complaints of some private training colleges trying to solicit bribes from students to upgrade marks or falsify attendance records, no such complaints had been aimed at universities.
