So far as I understand it, "bluetongueskinks.net" is a forum, not a breeder. We get e-mails here at BP.net by people asking to buy this or that from us, and we ignore those as well. Now, the forum may be connected to or owned by a particular breeder, I'm not sure...but I'd be willing to bet that if so, it's someone that lives in Australia. Most of their members with active breeding and unusual blueies live in Australia and none of them can export their animals.
Brian Barczyk (BHB Reptiles) is getting into blue tongues. His are from Indonesia rather than Australia. He's got some axanthic-looking animals, if I remember correctly, but I don't know when he'll have babies available. You could write to him and ask, though.
It's extremely unlikely that you'll find any actual Australian localities available, much less any of their exciting morphs. If you do, be very careful about the source, because the last thing you want to buy is illegally smuggled animals.
EDIT: Well, disregard some of that. The forum is owned by the breeder, and the breeder is in the US. I do wonder how they got all those different lines of Australian animals, but I guess if they've been at it long enough, they got animals that came into the States before Australia shut down their exports. Anyhow...good luck with that.
