Australia here too - Had the same kinda problem with BDB I liked the look of their retail products but couldn't get anyone to reply to my 2 emails and Facebook message. You can try trend beauty they're a supplier, but I know they were closing down very soon but they did send me a contact for another supplier in their last email.
I also am not a fan though. You can get the same result with a wax/thread and tint. The only difference is they fill them in with makeup after to give that perfect look, I'd feel like I'd be ripping off my clients charging them that price
