All indicators point to these being real, but angled toward tourists visiting Antarctica.
Either way, they are easily ordered through eBay and are not expensive, so I decided to check them out for myself.


These are strange banknotes, to say the least.
The guy on the $20 note reminds me of Ron DeSantis, which is also a little odd.
Full sets of these notes can be purchased on eBay from a number of sellers, and would cost less than $20.
