Mr Shirinia is part of the ACT Parks Rural Fire Brigade, which was one of the first interstate responders to the Blue Mountains fire that struck last week.
"I've been helped by a lot of people in Australia, and I think [firefighting] is a way I can give the favour back," the 31-year old says.
The Iranian man spent 11 days on a boat coming to Australia from Indonesia, before being intercepted and put in immigration detention.
"Each day I was expecting to be drowned at sea," Mr Shirinia says. "It was my only choice."
He still has family in Iran, and is reluctant to talk about why he left, except to say it was his only option.
