Greens Senator for South Australia Penny Wright has announced she will be stepping aside, due to illness in the family.

"I have thought very carefully about this step. I am disappointed to be leaving the Senate and my colleagues but I know that this is the right decision for my family and me," said Senator Wright.

"As a founding member of the Greens in South Australia, I'm proud of what our party has achieved so far and I know that we have high quality candidates who will be nominating as my replacement.

The 2015 Budget has no vision for the future of South Australia, say SA's Australian Greens Senators.

Senator Penny Wright said the Government was continuing to protect big business at the expense of everyday South Australians.

"The Abbott Government has absolutely no vision for South Australia's future. Rather than finding new sources of revenue from the big end of town, this Budget cuts one vital service to fund another," Senator Wright said.

Senator WRIGHT (South Australia) (14:25):  I too stand today to offer a personal reflection on the life and legacy of former Prime Minister Malcolm Fraser, and to offer my sincere condolences to his family and loved ones.

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'.
