I buy most of my hardware from Little Bird too - I could easily source it cheaper but they provide awesome service. I attended a great presentation of theirs showcasing http://ninjablocks.com/
I'm also from Australia and I could list at least a dozen places I would buy an Arduino from, before using your website that's less than a month old, and provides no contact details.
