On Monday, the Regional Universities Network had made the only submission to the Senate inquiry into the government’s bill to toughen up student loan repayments. But with two hours to go before deadline yesterday another 17 appeared on the Senate committee’s site.  Organisations addressing this significant (certainly for low-income graduates) bill include the Innovative Research Universities, the Council of Australian Postgraduate Organisations, the NTEU and eight universities. Graduates, you know who your friends are.
