The Australian Greens have called on federal National MPs join the NSW branch in publically advocating for the full six years of Gonski funding.

Australian Greens spokesperson for schools Senator Penny Wright commended NSW Education Minister and National Party member Adrian Piccoli for his speech in support of the full Gonski funding at the NSW Nationals conference.

"As Mr Piccoli says, funding the full six years of Gonski will benefit country schools the most," Senator Wright said.

Greens Senator for Western Australia Scott Ludlam was in Collie today talking with locals about the Greens' plans for Collie as a renewable energy generation hub.

Senator Ludlam, who earlier this year released Energy 2029 - a costed, technical plan for how WA's main electricity grid could switch to 100% renewable energy generation - said Collie should be one of five regional Renewable Energy Zones as it had key attributes that made it the right place to generate renewable energy.

The Greens today launched a plan to address the affordable housing crisis by creating a new local prefabricated housing industry in WA's South West.

Greens Senator for Western Australia Scott Ludlam said the manufacture and installation of prefabricated housing made with local sustainable plantation timber will be a boost for local jobs, while delivering much-needed housing.

Senator Ludlam made the announcement today in Bunbury, home to WA's largest pine sawmill at Dardanup.

The Australian Greens' plan to  invest more than half a billion dollars in mental health services across rural and regional Australia will save lives and build stronger communities, say Senators Penny Wright and Peter Whish-Wilson.

Launching the party's rural mental health policy in Launceston today, Australian Greens' mental health spokesperson Senator Wright said the policy was based on recommendations sought directly from rural communities.

"Years of under-investment in rural mental health continues to cost lives all across country Australia," Senator Wright said.
