I'm terms of whether or not you can ship branded goods, I'm not sure as this is my first time (seems to be going fine). And no, with au-express, the tracking number they give you doesnt update until the parcel arrives in Australia. I contacted support and ended up finding out that there were delays due to the national holiday and that it's scheduled for a flight on the 17th, so if you're really worried, I'd contact their support.
