I'm not sue if I fully understand your question, there are quite a few very reliable AU domestic vendors who are mostly reselling product bought from o/s on SR. The price buying domestically though is quite high hence why many people order from o/s at a fraction of the cost. If you want fast and reliable service avoiding customs and are happy to pay the premium for that service they buy domestic. If you are happy to take your chances with customs and a longer wait then go o/s. I have had very good experiences with Neon Lights, Enter The Matrix, aussieExpress for domestic MDMA if that helps.
