The Ulladulla High School P&C has asked the community to write to all key minority senators, urging them to “deliver the full Gonski funding”. 

The only public high school in the area is set to lose $933,040 in government funding under the new plan, when compared to the original Gonski agreement. 

High School Principal Denise Lofts said the original Gonski funding had, so far, allowed the school to run a “myriad of programs”, including outdoor education and skills for life programs.

“We will lose $900,000 over the coming years if Gonski is cut,” she said. “Everything is on the line right now.”

Mrs Lofts said the Coalition’s plan would see students miss out on much-needed support. 

The plan passed through the Senate on Thursday night with slight adjustments, meaning schools will see changes to funding from 2018.

Senators argued for an extra $4.9 billion in funding, with the spending timeframe sped up from 10 years to six.

The reviewed plan will see the Coalition pump an extra $23.5 billion into the nation's schools over 10 years than it promised in last year's budget.

“Our students will miss out on the support and assistance they need,” she said. 

“Mr Turnbull’s 10-year plan is not what the Gonski Review recommended. It locks in the over funding of private schools and the under-funding of public schools.”

NSW Parliamentary secretary for education Gareth Ward said the state government wanted the “original agreement” they had with the commonwealth fulfilled. 

“Naturally, we welcome increase in funding to schools,” he said. 

“We believe a tried and tested model should be fully funded.

“Obviously we want to continue that we agreement is honoured. I am pleased that the commonwealth has recognised the need for increased funding.”
