I am just going to comment on what i have experience on with that being said.
Also please note i am not here to endorce, enforce or moderate this thread, i am only posting what i feel could be done or should be done to help long standing members in the aussie community.

I feel it would be in good faith to show the beligas brand products you are a reseller for are proved authentic.
I have a good amount of experience with belgias and use it myself, few things of note here.
Every vial has silver foil on the box you can rub off and underneath it is a code that you can enter into the belgias site to prove if it is fake or authentic.
Does your packaging have that ? If so maybe in good faith you can show the aussie community that code, verify that code and post up the results if it is authentic or not.
Boxes have a qr code you can scan as well which i did see in one of your photos, transparency goes a long way with people in the aussie community.
I will also say ive seen alot of over here and on the American side of evo, one thing i Have never seen was one person using belgias or even mention beligas in the aussie community, because it would have to be shipped in international, no-one on the aussie side of things is gonna take that risk with how stringent customs is for the aussie guys.
Just my take after reading this entire thread.
