This is nothing new. :O Used to have stuff like this in Mexico all the time, you could essentially pop/pull the top off the can and there would be a sandwich inside.
Yeah, that's actually... not bad at all. No weirder than stuff I've eaten out of a Japanese vending machine.
(My god, a report that actually shows what the product really looks like and tries to find out more about it?! What a concept! Don't those Aussies know you're just supposed to snark about the brain-break and never try anything yourself?)
