THE Greens have challenged the Nationals' candidate for Richmond Matthew Fraser to come clean on Gonski reforms.

According to Federal Greens candidate for Richmond Dawn Walker, the Gonski reforms will provide greater educational opportunities for thousands of children on the North Coast.

"Kingscliff High School would receive at least $2 million in extra funding each year for better resources, improved teacher quality, enhanced student learning and improved support for struggling students," Ms Walker.

Under the Gonski reforms, funding would start flowing into NSW schools early next year.

The future of the planned changes to school funding appears uncertain however, with opposition leader Tony Abbot threatening to abolish the reforms unless they are backed by every state and territory by a June 30 deadline.

With the deadline looming just days away, Ms Walker is upping pressure on Mr Fraser.

"It's important that the Nationals' candidate Matthew Fraser informs our community what his position on Gonski will be in the face of an Abbott government," Greens candidate Dawn Walker said.

In response, Mr Fraser claims that Labor's planned changes to school funding under the Gonski review are uncertain.

"The federal budget has revealed Labor is actually reducing school education funding by $325 million over the forward estimates, despite the claims of extra spending," he said.
