The Australian Greens have welcomed the Syrian refugees beginning to arrive under Australia's emergency intake, cautioning the world against lashing out in anger over the horrific attacks in Paris.

"A united Australian community is much stronger in helping to defeat these threats than one that's divided. Hate is the problem here, it's not the answer," said Greens Leader Richard Di Natale.

"As a community we need to recognise that the people seeking refuge in Australia are fleeing the kind of violence and barbarism that we've seen in Paris.

The Australian Greens have condemned the Abbott Government's decision to commence airstrikes in Syria, warning it will worsen the refugee crisis and aggravate extremism.

"At a time when our community is desperate to show compassion to people fleeing war in Syria, Tony Abbott is dropping bombs," said Greens Leader Richard Di Natale.

"I'm so proud of the way Australians have told the government loud and clear that we are strong enough to offer protection to people seeking refuge from war.

Greens Leader Richard Di Natale says it shouldn't be up to Tony Abbott or the United States to decide if Australia will join air strikes in Syria.

"Australia needs to have its own independent foreign policy, and the Parliament should decide whether or not we send Australians into harm's way," Senator Di Natale said.

"Ultimately it doesn't matter if the request to bomb Syria came from Mr Abbott or the US - the only way to be sure that political self-interest doesn't determine whether our troops are put in danger is for the Parliament to decide.

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.

Greens Leader Christine Milne says mission creep in Iraq has accelerated and Prime Minister Tony Abbott has committed troops to an unwinnable war.

"Tony Abbott continues to blindly follow the US further and further into the Iraq quagmire. He has absolutely zero idea of what success would look like," Senator Milne said.

"The Prime Minister says he will review the deployment after 12 months but against what criteria? What will constitute success or failure, what will determine whether we stay or come home?
