Greens Senator for WA Rachel Siewert has urged the Minister for Heritage, Peter Garrett to take seriously potential damage to a national heritage-listed site on Western Australia's Burrup Peninsular.

"We hear that the Heritage Minister's Department has gone to the trouble of seeking expert archaeological and legal advice about whether multinational Cemex has damaged artefacts of national heritage significance on the Burrup," Senator Siewert said.

"We now need to know the outcome of this advice and what Minister Garrett plans to do about it.

Today, Federal Greens senators for WA Rachel Siewert and Scott Ludlam joined WA Greens Upper House MPs Giz Watson, Robin Chapple, Alison Xamon and Lynn MacLaren on the steps of the WA Parliament to congratulate Adele Carles on her historic win of the seat of Fremantle.

"This is the first time the Greens have ever beaten the ALP on primary votes," Ms Carles said.

"The people of Fremantle have entrusted the Greens with their first seat in the WA Legislative Assembly.

The Senate today moved to establish an inquiry into the Government's handling of awarding employment services contracts.

"The Greens and Coalition Senators today referred this issue to a Senate Inquiry to review the decision making processes, and the outcomes of the tender process. The key questions are whether Australia's employment services will be better or worse as a result of this process and most importantly will those Australians without a job be supported as they need to be," said Australian Greens Senator Rachel Siewert.

Australian Greens Senator for Western Australia Rachel Siewert today expressed deep concern that the Federal budget leaves many people behind and does not develop the new green economy.

"While the increase of $32.49 per week for single aged pensioners is a welcome step, the Government has not addressed the crisis Australia is facing in aged care. In fact, for Western Australia I am deeply concerned that beds may need to close and many older people will face deeper hardship, particularly in regional and rural areas," said Senator Siewert.

The latest impasse between Kimberley Traditional Owners and Premier Colin Barnett over the siting of an LNG hub in the Kimberley highlights the State Government's poor handling of the decision-making process, the Australian Greens say.

"We are now seeing Premier Colin Barnett preparing to lay the blame for a failure to reach an agreement squarely on the shoulders of Traditional Owners, when in reality he is to blame for skewing the process," Greens Spokesperson on Indigenous Issues, Senator Rachel Siewert said.

Tens of thousands of WA university students returning to study in the next fortnight will be able to qualify for a $950 Government Training and Learning Bonus, thanks to an extended deadline negotiated by the Australian Greens.

“Under Kevin Rudd’s original plan for the $42 billion economic stimulus package, only those students who had enrolled by 3 February could qualify for the $950 bonus,” Greens Senator Rachel Siewert said.

“However, as a result of the Greens’ negotiations in the Senate this deadline has been extended to 31 March.”

Greens highlight emergency relief for struggling families as more mines close

Western Australia must create a more resilient economy that can ride out mining busts and the current round of job cuts, according to the Australian Greens.

“The need for emergency relief is becoming evermore apparent as each day more Western Australians find themselves out of work through mining closures and cutbacks,” Australian Greens Employment and Workplace Relations Spokeswoman Rachel Siewert said.

The Australian Greens today called on Federal Environment Minister Peter Garrett to press ahead with the ongoing strategic assessment process to find the best location for an industrial Hub in the Kimberley, saying that he should not approve any LNG developments in the region outside of the agreed process.

"Colin Barnett's attempt to return to the old days of trampling on Aboriginal rights and environmental heritage is inappropriate and out of step," said Senator Rachel Siewert.

The Australian Greens today voiced their concerns over the future state of industrial relations in Western Australia, after comments from WA Treasurer Troy Buswell that the state system would be overhauled.

"This call from the new Liberal leadership in WA is a purely political reaction to the proposed industrial relations changes at a federal level. What is needed is considered debate and consultation with all involved, not political points scoring," said Australian Greens spokesperson on industrial relations Senator Rachel Siewert.
