@ Markus. No problem. That's the name of the dish "Mixed Grill", it's not a generic fry up, it's got set ingredients, if you ask for one in a cafe/pub the photo shows what you'll get. A "national dish" we aussies all know and love.
It's just not known overseas, we keep the good stuff for ourselves and secret from the rest of the world.
As for cuisine instantly recognisable as Australian...we don't have anything yet.
