REGIONAL universities made a last ditch effort to convince crossbench senators to pass the Abbott government's controversial higher education reforms on Thursday.
The government continues to negotiate with crossbenchers, but has so far fallen short of getting the requisite support.
Regional Universities Network chairman Professor Peter Lee again called for the reforms to be passed with changes.
He also rejected claims that regional students could face $100,000 in fees for degrees under the deregulated system.
Mr Lee said it was time to "end the uncertainty".
He also said the Senate should endorse a recent Senate committee's recommendations for extra help for regional students and an adjustment fund for universities outside the major cities.
The Palmer United Party, Labor and The Greens remain opposed to the reforms, with one week before sittings end for this year.
