Greens Leader Christine Milne says Nepal is still in crisis, almost a week after the earthquake hit, and Australia must do more to help.

"There's a huge amount of concern around our country right now. People are worried, they want to help. We all want to see more stories of survival," said Senator Milne.

"Australia can send more money, and I'm pleased the Foreign Minister has announced a further $5 million in aid funding . We should also send more military personnel and search and rescue capacity, as this is a role which the ADF is well equipped and experienced in.

Greens Leader Christine Milne has proposed further actions in response to the Bali Nine executions and says the Australian Parliament must demonstrate its cross-party opposition to the death penalty with better safeguards to protect Australian citizens from state-sanctioned execution overseas.

"What happened to Myuran Sukumaran, Andrew Chan and other Australians before them must not happen again. We have a responsibility to do all we can to oppose the death penalty and protect people from it, wherever it exists," said Senator Milne.

On behalf of the Australian Greens I express my deepest sympathies to the families and friends of Andrew Chan, Myuran Sukumaran, and the six other people who have been executed in Indonesia overnight.

Myuran and Andrew will be remembered for overcoming their past to live meaningful lives, even from prison, not just for the way they died.

Their actions over the past ten years were testament to their remorse, and have given many of their fellow prisoners an opportunity to live better lives.

It is a tragedy Andrew and Myuran were denied their own second chance.

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?

Greens Leader Christine Milne says it's no surprise that Australian officials have been instructed to try to protect fossil fuel subsidies at the OECD.

"The Abbott government is a wholly owned subsidiary of the coal industry. There's no other way of looking at it," said Senator Milne.

"Anyone who was unsure if the government's attack on the Renewable Energy Target was anything other than attempt to prop up coal would now be in no doubt.

Tony Abbott's Cabinet is expected to make a formal decision to sign Australia up to the new Asia Infrastructure Investment Bank on Monday, but the Greens say tighter environmental and human rights standards must be agreed to first.

"Cabinet should not commit to joining the new bank until tighter environmental and human rights standards have been agreed to," said Greens Leader Christine Milne.

The Australian Greens today join the community in honouring the service of the men and women who served in Afghanistan as part of Operation Slipper and welcome them home.

"Around Australia today people have come together to say thank you to all those who put their lives on the line in Afghanistan, and to honour their service, and I join them," said Greens Leader Christine Milne.

The Australian Greens Leader, Senator Christine Milne, moves a Senate motion calling on the government to support legislation that enables the Parliament to decide when Australian troops are deployed overseas.

Greens Leader Christine Milne talks with Walter Williams on 2UE, 4BC and radio stations along the east coast about Liberal and Labor combining to deny the Parliament a debate on sending more troops to Iraq, leaving it to Tony Abbott to make another captain's call.
