I tried searching, but didn't find any info about this, anyone know what it's about?

Luckily, they are just Koala, Not much milk spot occurring on them.
They are Bullion coins just like many, people often name the finishing to make them more attractive.
There are plenty around and don't command much premium on them.

Thank you, i was just wondering if there was some variation i didn't know about, especially since that one ebay article is selling for double the market rate. Cheers.
