A masterpiece. despite the worst accents I have ever heard in my life.

Leaving aside whether your take on the challenge is successful, and whether it's a good idea to insult one of the judges, the primary thing I'm concerned about with regard to this song is that it's a joke song, and it's just not funny. And if none of the jokes land, I don't really hear anything else to appreciate here. It has none of your usual performance and production finesse. The Australian accents are horrendous, there's no message to the lyrics, and even the melody strikes me as facile and unmemorable. Better luck next year.
