My favorite reference is Zach Griffith's website Bluetongueskinks.net

His site is home to many Tiliqua keepers, hobbyists, and breeders. It has probably the largest and most detailed care sheet ever produced for Blue Tongue Skinks, and the forum is filled with casual BTS pet owners, as well as some hard core keepers with multiple animals and years of experience.

(I prefer the Australian Northern and Eastern BT's for a first time animal.)

Good luck with your acquisition.
