Sent RUI a message about shipping to Australia and got this response....
Thank you for your interest. We have shipped to Australia many times with success. However, we don't know all of your Country's Custom laws so after we ship, it's out of our hands. Our packages are shipped discretely and marked as "Commercial Sample" with a $0.00 value. We are not responsible for lost product. Large quantities are not accepted. For International Orders, please allow 10 to 15 business days for delivery. If your order is seized, with proof of the Seizure Document we can refund 50% of the item cost only. Thanks!
Definitely worth a shot.
