Australian and Fijian soldiers are being deployed to a disputed region between Syria and Israel on a United Nations peace-keeping mission.
They are awaiting final UN approval before travelling to the disputed territory of Golan Heights.
A Defence spokeswoman has confirmed it has nothing to do with the United States' recent withdrawal from north-eastern Syria, on the other side of the country.
"I just met some of the (Australian Defence Force) boys upstairs who are going to be deployed with the Fijians over in Syria," Prime Minister Scott Morrison told his hand-picked rugby league team in Suva on Friday before they played their Fijian counterparts.
"Our Australians are going over there, training them, supporting them with what they're doing on the field."
The final approval could be given within weeks.
It was an encounter with ADF rugby players who played against Fiji's Army Bears earlier in the day that led Mr Morrison to spill the beans about the mission
The co-deployment is with the UN Disengagement Observer Force, which has been perched in the area between Israel and Syria since it was established in 1974.
The Defence spokeswoman said it was part of a long-standing commitment from both countries towards UN peace-keeping in the Middle East.
"This deployment is not related to current events in north-eastern Syria," she said.
Mr Morrison on Thursday expressed his "deep concerns" about Turkey's military incursion into north-eastern Syria, over fears it could lead to the resurgence of Islamic State.
Turkish warplanes and artillery have hit Kurdish militia targets in northeast Syria in an offensive that has killed hundreds of people, forced tens of thousands to flee and turned Washington's establishment against US President Donald Trump.
Mr Morrison has been in direct contact with the Turkish and United States governments to express his concern over the actions.
The Prime Minister has defended Mr Trump over the contentious withdrawal of US troops from northern Syria, which paved the way for the Turkish incursion.
Kurdish forces have provided security to camps where the Australian wives and children of Islamic State militants are being held.
The government is concerned for the Australians in these camps but won't put officials in harm's way to rescue them.
