I have a hard time finding part diagrams for a Ford Fiesta. It's like the car never existed, at least not for 2009. Anyway, it's called an
Front Bumper Valance. Part # is 8A61-
17B769-A. The bold part really matters.
Here's a Ebay listing of it. Alibaba listings of that part.
I just learned something and that's to never buy a Ford Fiesta. Can barely find any car parts for the stupid thing.

I might be wrong. It might also be called a stone deflector. The part number is 17808, but the problem is that's the part # also for the rear deflector. I'm pretty sure they don't look the same. Might be also because you're from Australia and the part numbers I find might be for America. So 17808 could be correct.
I found this info here. You can try asking people there since they're all about Fiesta's. Y U Do Dis Ford?
