CANBERRA, May 11 - Labor has confirmed its opposition to a two-year efficiency dividend on teaching funding to universities, a 7.5 per cent increase to student fees, and a $13,000 drop in the HELP loan repayment threshold.

All up, the government hopes to save $2.8 billion from its latest plans to overhaul university funding.

"Clearly, Malcolm Turnbull thinks it's fair to saddle young Australians with a big uni debt at the same time as they are trying to buy a house, or start a family," Labor education spokeswoman Tanya Plibersek said on Thursday.

"He is completely out of touch."

Legislation for the changes will be introduced to parliament on Thursday.

The Greens also oppose the cuts, meaning Education Minister Simon Birmingham will have to win over 10 of the 12 crossbenchers.

Independent senator Jacqui Lambie has already indicated she's opposed.

The new package does away with changes proposed in the 2014 budget, including a 20 per cent cut to university funding and complete deregulation of fees.

Previous education minister Christopher Pyne made two doomed attempts to convince senators to support the old plan.
