Services to veterans must not be interrupted by the planned closure of the General Repatriation Hospital, says Australian Greens Senator for South Australia Senator Penny Wright.

Senator Wright said the new centre of excellence must be fully operational before the Repat is closed, and consideration should be given to the cultural significance of the site for veterans.

"The General Repatriation Hospital is more than just a hospital to many veterans - it is a place to meet and to remember and has had a culture that respects and understands veterans," Senator Wright said.

Australian Greens Senator for South Australia Penny Wright says South Australia has been hardest hit by the ABC job cuts, with 7.30 SA, the Port Augusta radio bureau and local TV production to close.

"Today's announcement is gut-wrenching. Our local ABC is a vital part of South Australia's media landscape and our community," Senator Wright said.

"Christopher Pyne's hypocritical petition to save South Australian TV production has proved as useless as Tony Abbott's promise of 'no cuts to the ABC'.

Australian Greens Senator for South Australia Penny Wright says the closure of South Australian ABC TV production and outsourcing of administration would be a serious blow to the state and could cost up to 150 jobs in Adelaide.

“The government’s cuts to the ABC will decimate the Adelaide ABC workforce and will have serious flow on effects – especially for a smaller city like Adelaide where the job market is tight,” Senator Wright said.

The Australian Greens said today that South Australian hearings for the Senate Inquiry into income inequality will focus on issues affecting equality in the state, including the impact of the Government's budget on the most vulnerable members of the community.

The Committee is chaired by Australian Greens Senator Rachel Siewert, who initiated the Inquiry.

Waiting times at South Australian emergency departments will triple if the Abbott Government's $7 GP co-payment is introduced, the SA Health department told a Senate inquiry today.

The Senate Select Committee on Health also heard the South Australian Government was considering a further administration fee of up to $30 dollars to cover the cost of collecting the co-payment in emergency departments.

Australian Greens Senator for South Australia Penny Wright says Prime Minister Tony Abbott must end the uncertainty around the future of the Renewable Energy Target, as South Australia announces plans to raise its target to 50 per cent.

"The Renewable Energy Target is cutting pollution, creating jobs and will bring power bills down," Senator Wright said.

The Australian Greens say the Abbott Government is shirking responsibility by waiving a new environmental impact statement for the proposed expansion of Olympic Dam.

"The Federal Government needs to do its job and stop putting the private profits of the big mining companies ahead of the environment," said South Australian Greens Senator Penny Wright.

"This is a short-sighted measure, which shows how little the Government cares about environmental protection."
