Hi Pltgyst (how do you pronounce that?!?!)
....this is a long shot but do you have any spares?
There's an "r" in there -- pltrgyst -- and it's pronounced as "poltergeist". Comes from the 1980s, when ARPAnet/Internet logons were limited to eight characters.
I have five $1s, two $5s, and one $20 possibly still available. Have no idea what mailing would be to Australia, though -- probably similar to Europe, which was $13.50.
