Gold Coast Pet Centre on Kortum Dr at Burleigh is a good shop - upstairs has an impressive (at least, from the few shops I have seen) reptile set up. Nerang Pet Barn pretty good too, but I haven't been there in a while.
Been to Gold Coast Pet Centre good selection But the reptile "expert" wasn't able to tell me much about the import/export and was quite a retail mark up. Besides that was quite good.
