In line with No Shark Cull Rallies across the country Greens Senator spokesperson on marine issues Rachel Siewert has today announced a notice of motion that will condemn new Serious Threat Guidelines of the Western Australian Government.

"The first week back in the Senate we are moving to highlight that in Western Australia the move towards a revised catch and kill policy is just as indiscriminate and as nonsensical as hanging hooks along our coast throughout the summer.

The Australian Greens said today they were concerned that a loophole may be created that still allows Colin Barnett to deploy drumlines off WA beaches.

"I think the Federal Government would most likely have rejected the Premier's application before it was withdrawn at one minute to midnight," Senator Rachel Siewert, Australian Greens marine spokesperson said today.

The Australian Greens said today that Premier's decision to withdraw his shark cull from Federal Government assessment should finally signal an end of the flawed policy.

Reports today indicate that the WA Government has withdrawn an application for an exemption to the EPBC Act, which would have allowed the Premier to carry out a three year shark cull off Perth and the South West of WA.

"I hope that by withdrawing the shark cull from federal assessment, Colin Barnett is abandoning this cruel policy," Senator Rachel Siewert, Australian Greens marine spokesperson said today.

The Australian Greens are calling on the Federal Environment Minister Greg Hunt to support the recommendation of the WA EPA and reject Colin Barnett's shark cull.

"The EPA's decision shows that the science does not support this cull," Senator Rachel Siewert, Australian Greens marine spokesperson said today.

"Federal Environment Minister Greg Hunt will have the final say, and given the extensive body of evidence highlighting the flaws in Colin Barnett's plan, we call on him to support the EPA's recommendation.

Scientists and surfers have visited Parliament House today to speak about non-lethal alternatives to WA Premier Colin Barnett's shark cull.

Professor Jessica Meeuwig from UWA, Professor Rob Harcourt from Macquarie University, Dr Charlie Huveneers from Flinders University and Brendon Donohoe, Chairman of Surfrider Foundation Australia gave a briefing for MPs and staff in Parliament House today, co-sponsored by Western Australian Senator Rachel Siewert and MP for Fremantle Melissa Parke.

The Senate has today supported an Australian Greens motion noting the letter of concern from 305 scientists about the cruel WA shark cull and calling on the Federal Government to reject the proposal.

"My motion acknowledges the contribution of the 305 scientists and experts who signed a Letter of Expert Concern showing that there is no justification for Colin Barnett's government to continue this cull," Senator Rachel Siewert, Australian Greens marine spokesperson said today.

The Australian Greens today urged Minister for the Environment Greg Hunt to listen to the large group of Australian and international scientists and experts rejecting Colin Barnett's shark cull.

More than 300 leading scientists and experts have signed a Letter of Expert Concern, which has been sent to the WA EPA and Minister Hunt, as part of the assessment process for the proposed three year extension of WA's shark cull.
