Former federal MP Wyatt Roy was reportedly caught up in a firefight between ISIS militants and Peshmerga forces in Iraq last week.
Mr Roy, 26, told SBS News around 15 ISIS insurgents launched the attack on Kurdish forces near the town of Sinjar last Thursday.
The former Liberal minister told the broadcaster the firefight ended when Coalition airstrikes were called in.
"Very quickly after we were attacked - it was obviously quite a serious situation - the Peshmerga called in an airstrike and probably within a half an hour, forty minutes, the jets were overhead," Mr Roy said.
Mr Roy told SBS he was in the region as he "wanted to visit and see for myself, in a way that I really couldn’t have done as a member of parliament."
The federal government has deemed nearby Mosul a "declared area", which prohibits Australians entering the region.
It is unclear whether Mr Roy would have breached Australian law with his trip.
He has since flown out of Iraq.
Mr Roy, who lost his seat of Longman at this year’s federal election, was elected to the lower house at the age of 20.
During his term as an MP, Mr Roy highlighted the plight of the Kurdish Yazidi community, who were persecuted by ISIS militants.
