The Prime Minister has warned that any hope of implementing the reforms Gonski Review of school funding would vanish if the Government was to lose the September election.

In an address to the Australian Education Union’s National Conference, Prime Minister Julia Gillard was at pains to stress the prospect of the reform was very much contingent on a Labor victory this year.

“The Government I lead will deliver Gonski. If this Government goes, Gonski goes with it. Mr Abbott's Liberals will always stand in the way of this reform,” Ms Gillard said in her speech.

Under the proposed reforms, each school would receive funding depending on the number of students enrolled, with extra funding being made available depending on other factors, such as disabilities, geographical distance and English skills.

“This isn’t just tinkering around the edges. It is the biggest reform to schools policy in 40 years,” Ms Gillard said.

Ms Gillard’s warnings come after the Victorian Government outlined its own $400 million school funding reform package, which it claims is based around the core findings of the Gonski Review.
