Yarra 3DX is active too. They sent a nice letter and sticker to their crowdfunding supporters.
If I where you I'd wait a few days and if you still don't have the letter try to contact Comhear. If you don't have an e-mail address you can always use the contact form:Haven't got a letter from them yet
Did in anyone else in Australia order one and get a letter yet? Sorry for continuing the slight derail.

Or maybe you are lucky and they read this thread and react.
