You haven’t lived until you’ve had a hungover sausage sizzle.
Fairy Bread.
Despite the fact that it confuses the rest of the world, fairy bread is probably the food invention that we are most proud of. Basically grab a slice of white bread, spread with butter, and top with 100s and 1000s. You can't have a kid's birthday party without a plate, but that's not to say it's not for adults as well.
Lamingtons.
It's essentially a sponge cake coated in chocolate and coconut, sometimes with jam in the middle. You'd be hard pressed to find a bakery in Australia that isn't stocked with lamingtons, probably because they're the best mid-afternoon snack around.
Tim Tams.
Yes, they're now available in a few places in the USA, but they just aren't on the same level as Aussie Tim Tams. Though they do come in a range of flavours (shout out to chewy caramel), we all know that original is always the best. Oh, and you haven't lived until you've done a Tim Tam Slam.
Milo.
Milo is basically malt powder to be mixed with milk, but don't let that disgusting description fool you; Milo is the drink of the gods. It's important to get the milk/Milo ratio just right. But when we were younger and mum wasn't looking, it was all about trying to heap as much Milo in as possible.
