Ms Gillard has recorded a short video for Triple J's breakfast show, as part of their "end of the world" celebrations. The world is supposed to end on December 21, according to interpretations of the Mayan calendar.
"My dear remaining fellow Australians," Ms Gillard begins in the clip. "The end of the world is coming. It wasn't Y2K, it wasn't even the carbon price."
The Prime Minister took time out from her preparations for Friday's COAG standoff to film the clip in Melbourne on Tuesday.
The jokes were a joint effort between the radio station and Ms Gillard, thus explaining the mix of pop culture references and political spin.
"Whether the final blow comes from flesh eating zombies, demonic hell beasts or from the total triumph of K-pop, if you know one thing about me it is this: I will always fight for you to the very end," Ms Gillard says in solemn tones.
Finishing the video, the Prime Minister observes: "At least this means I won't have to do Q&A again."
