The Australian Greens have announced a suite of new costed initiatives to protect the environment no matter who wins government.

"I don't think anyone is surprised the old parties are ignoring the environment this election," Australian Greens Leader Senator Christine Milne said.

"Tony Abbott and Kevin Rudd think it's an afterthought portfolio, making token announcements while slashing major environmental programs.

"The Greens will plug the gaping void left by the environmental vandalism of the two old parties.

The Australian Greens have a $46.5 million plan for teaching kids what they need to know about food including funding up to 800 new school kitchen gardens and ensuring healthy eating and nutrition is part of the national curriculum.

"One of the best things we can do to help our children lead a healthy life is to teach them about food - how to grow it, choose it, buy it, cook it and store it," Greens Leader Senator Christine Milne said.

The Australian Greens have pledged a $100 million boost for tourism marketing as the old parties threaten to destroy our tourism jewels and the half a million jobs that rely on them.

"Our natural attractions are Australia's biggest tourism drawcards," Greens Leader Senator Christine Milne said.

"They define us in the international mind. Every year thousands of people visit places like the Great Barrier Reef, Kakadu and Uluru and come to see unique animals like the koala, leadbeater's possum and Tasmanian devil.

The Australian Greens have welcomed news that both Labor and the Coalition have now joined the Greens in supporting the continuation of Antarctic climate and ecosystems research but say the promises still fall short of what is required.

"In a race for votes in Tasmania, it is not surprising they are making a last minute pitch by announcing they will increase support for Antarctica," said Australian Greens Leader Senator Christine Milne.

Australian Greens Leader Senator Christine Milne says obfuscation by Tony Abbott on details of the Coalition's savings measures is a deliberate attempt to hide his razor gang from voters.

"Tony Abbott wants to cut environment spending and the public service to fund tax breaks for the rich but he isn't being honest with the Australian people about it," Senator Milne said.

"Mr Abbott wants total control of the parliament and for the Senate to wave through policies he won't even come clean on. He is hiding the ruthlessness of his razor gang from voters.

Christine Milne joined a panel on ABC Saturday Extra to outline the Greens' vision for Tasmania's clean green and clever economic future.

Tasmania has so many advantages that the Greens have worked hard to develop, from the innovation economy with scientific research hubs and the NBN, through tourism and ecosystem services with wilderness protection, creativity and the arts, growing healthy food & much more.

Australian Greens Leader Senator Christine Milne today announced a $120 million plan to save our plants and animals from extinction.

"If we don't act now, Australia will lose some of our greatest natural treasures," said Senator Milne.

The Australian Greens have rebuked the Prime Minister for suggesting coal seam gas could help lower electricity prices in Australia.

"Extracting more gas won't reduce its price any more than digging up more gold reduces the gold price," said Australian Greens Leader Christine Milne.

"Kevin Rudd is confused by the basics on coal seam gas in Australia. Increased production will have zero impact on electricity prices because the industry is geared up to export it out of Queensland.

The Australian Greens have expressed alarm that Kevin Rudd is having secret discussions with at least one Liberal Premier about Australia's environmental laws. This comes on top of apparent plans to hand big polluters billions by ending the carbon price fixed period early.

"In his Press Club address today, Kevin Rudd announced that he wanted to reduce the ‘regulatory impost' on business by changing the environmental assessment process in Australia and that he had discussed this issue with Premier Barry O'Farrell," said Australian Greens Leader Senator Christine Milne.
