Greens Leader Christine Milne says it's about time federal funds started flowing for deradicalisation programs in Australian communities.

"It has been almost eight months since Australians were first sent off to another unwinnable war in the Middle East, but only now is the Abbott government starting to act on countering violent extremism at home," said Senator Milne.

Greens Leader Christine Milne says that Daesh is running a sophisticated propaganda campaign and the Prime Minister's response is inadequate.

"Where are the prevention programs Mr Abbott?" Greens Leader Christine Milne said.

"This propaganda is sophisticated and appealing to hearts and minds.

"It's not enough for the Prime Minister to just stand there with his eight flags and say "don't do it". That won't work. It a recipe for complete failure.

On behalf of the Australian Greens I extend our deepest sympathies to all those who have lost loved ones in yesterday's plane crash in the French Alps.

I am particularly sad to hear that a Victorian woman and her adult son have been killed. Our hearts go out to their family and friends.

We all travel; we've got friends who travel, children who travel. This is a tragedy that hits home because so many people have died, many of them young, and it appears so random. We get the sense that in other circumstances, it could have been any one of us or our family or friends.

Australian Greens Leader Christine Milne says it's time the Abbott government used the money it has set aside for deradicalisation programs.

"It's easy to see what programs they've defunded, but not one cabinet minister can point to a program working right now to help communities deradicalise young people," said Senator Milne.

"It is time the Prime Minister stopped just pushing the terror button and actually got out there and started to work in prisons, in schools, and in communities to make sure that we counter the messages coming from the jihadists.

Prime Minister Tony Abbott is trying to shore up his leadership by scaring the community and pressing the terror button, says Australian Greens Leader Christine Milne.

"We've got a Prime Minister who is so desperate that he is trying to press the terror button in order to shore up his own position. It won't make us safer," Senator Milne said.

"He's fanning flames of fear, anxiety, difference and division, because it's about the only thing that can distract from those same problems within his own party.

"Real leadership will bring people together, not divide them.

Australian Greens Leader Christine Milne says 2015 is the year Australia should recognise Aboriginal and Torres Strait Islander people in the Constitution, with a referendum that is fully understood and supported by the community.

"I'm calling on Prime Minister Abbott to get his head out of knights and dames and giving honours to Prince Philip, and instead put real effort into the campaign for giving recognition to Aboriginal and Torres Strait Islanders in the Constitution," said Senator Milne.

On behalf of the Australian Greens, Leader Christine Milne is congratulating Rosie Batty on being named the 2015 Australian of the Year.

"I'm so pleased that Rosie has been recognised in this way for her resilience and incredible determination to make Australia a safer place for people to live," said Senator Milne.

"There were no dry eyes here on the front lawns of Parliament House as Rosie dedicated her award to Luke, saying he had not died in vain.
