Inequality in education will rise unless the Abbott Government commits to the full Gonski model in the next budget, says Australian Greens spokesperson for schools Senator Penny Wright.

Speaking as the AEU's Gonski road trip concluded in Canberra, Senator Wright urged the Abbott Government to commit to needs-based funding for every state and territory and deliver the full six years of funding.

"Since coming to government, the Abbot Government has done nothing to address the staggering educational equality in Australia," Senator Wright said.

As the Australian Greens spokesperson for Schools, I am very concerned submissions to the review are not being made public, as originally promised.

Given the high level of interest in the Abbott Government's announced review of the curriculum and concerns about the independence and qualifications of the selected review panel, I feel it is vital this review is conducted with as much transparency as possible.

South Australian Liberal leader Steven Marshall signed up to a dud deal for South Australian students, says Australian Greens spokesperson for Schools Senator Penny Wright.

"Steven Marshall has abandoned SA schools and is seriously risking the economic future of this state," Senator Wright said.

"Investing in our students is the best investment we can make for South Australia.

The Abbott Government's independent public schools system will create a hodgepodge of different schooling systems all around the country, Australian Greens spokesperson for schools Senator Penny Wright said today.

Questions asked by Senator Wright in estimates hearings last night revealed each state and territory will be able to decide their own application criteria for independent public schools and develop their own levels of autonomy.

The Abbott Government will spend $300,000 in rushing a review of the national curriculum before implementation is complete, paying reviewers Kevin Donnelly and Ken Wiltshire $429 each per day.

Questions asked by Australian Greens spokesperson for Schools Senator Wright in estimates hearings today revealed the full costs of the review.

"This review is nothing more than an ideological exercise by the Minister based on his own paranoia about a "left wing bias" in schools," Senator Wright said.
