McDonalds Wagyu Beef Burger in Australia

Hey guys, just wanted your thoughts on the new wagyu beef burger that came out in Australia. Just had my first wagyu beef burger and i loved it, especially the new sauce that's int it, my be my new number one choice until they stop selling it!

What special burgers does everyone have in their country, i'm from Australia and think that this is the only country that has wagyu beef burgers.
