No word from Australia on more troops to work with NZ in Iraq

Australia is yet to announce it's sending any more troops to Iraq after our Prime Minister yesterday said New Zealand's deployment is likely to be part of a joint training mission with Australia.

More than 140 New Zealand military trainers, support staff and a security protection force are being sent to Iraq in May.

Australia already has 200 special forces soldiers in Iraq, but Foreign Minister Julie Bishop says the national security committee of Cabinet is reviewing the commitment.

The ABC says the government is set to announce that hundreds more Australian troops will be sent to the strife-torn nation as part of a joint mission with New Zealand to train Iraqi soldiers.

"We have had our presence in Iraq under constant review to ensure that we're achieving the best outcomes," Ms Bishop told Sky News.

She said no decision has been made and it's up to Prime Minister Tony Abbott to make any announcements.

Mr Abbott is due to visit New Zealand on Friday and ONE News political editor Corin Dann says it is still expected Mr Abbott will make an announcement some time before he comes here.

Dann says there's a little confusion about this. "John Key made it clear our forces would work in conjunction with Australian forces but not under an Anzac badge," he says.

"Now I think there was some expectation, certainly there is from media across in Australia, that there would be an announcement from Tony Abbott today that he would be sort of matching our deployment if you like.

"There are already Australian troops in Iraq doing work but it was expected that he would add to that, possibly today. And it is still expected he will make an announcement some time before he comes here on Friday. But we'll just have to wait and see," our Political Editor says.

Meanwhile, both the United States and Australia have welcomed Mr Key's decision to send troops to Iraq to support the fight against Islamic State.

But the decision has created clear division in our Parliament, with both opposition and Government coalition parties criticising the military involvement, even in a non-combat role.
