Serious Eats' Culinary Ambassadors check in from time to time with reports on food fare in their homeland or countries of residence. Here's the latest! —The Mgmt.
In the part of Australia that I lived in for most of my life we had very few "festivals" as such. What we did have, though, was the Royal Show. Every year the Royal Show tours Australia, stopping at untold amounts of places along the way.
One of, if not the, most common foods at the Royal Show was the Dagwood Dog, also known as the Pluto Pup. Essentially just a hot dog on a stick, dipped in batter then deep-fried, this is an absolute thing of beauty.
Generally the tip is dipped in tomato sauce (not ketchup) when you buy it, making it oh so much yummier, but oh so much harder to eat elegantly.
The thought of eating Dagwood Dogs at any other time of the year is enough to turn anyone's stomach, so this is very definitely a festival food.
