welovereptiles, may l ask why you want to know if you can breed stumpy's from different locations, is it that you want to cross-breed them and create a new colour phase.
Are you aware that in western australia you cannot keep the tiliqua rugosa aspera on licence, you can only keep the tiliqua rugosa rugosa on licence in western australia, that are found natually in the wild over there.
We don't want people like you going-ahead and cross-breeding these 2 sub-species of stumpy's, and then exporting them into western australia as tiliqua rugosa rugosa, when in fact they are half tiliqua rugosa rugosa and tiliqua rugosa aspera.
L know of a pet shop in western australia that got in serious trouble in 2003, from excepting tiliqua rugosa aspera from ultimate reptile supplies in adelaide, they were force to return the 8 of them back to ultimate reptile supplies and cop a fine for not saying on their import permit what they really are.
Lf l hear of anyone selling any australian reptile's under false names, or cross-breeding them so they can sell them in victoria or western australia, where their not on licence, you will be reported to your local wildlife and permit office in your state.
