Actually they do offer Global Priority Mail to Australia, but is has a max weight of 4lbs.... I know this for a fact as I ship at least 2 shipments Via GPM weekly....
BTW; I agree with what you said in your previous post.... The fist time you ship something International via USPS your head will start to spin, not to mention the employees working the desk are of no help at all!!!! Trust me I KNOW!!! My very first international order was accidentally shipped via USPS air post, no tracking # no insurance (that was my fault). The order was just over $6K, it got lost in transit and finally showed up 2 months later ....But at least it showed up!!!.... From now on it's EMS for me (Insured BTW)
Yea I forgot about that. I gues it blocked it out because I had 6 lbs in there for the weight.
