http://track-chinapost.com/?p=976 shows the average wait time for a parcel to Australia is 46days, but some parcel did take 93days to arrive. I'd suggest wait patiently and watch for your buyer protection period and ask an extension if it is running out soon,or open dispute for a refund.

I'm sorry for made this mistake , according to our statistics，the average wait time for a parcel to Austria about 96days, your parcel was received by China Post on May.20, and handed over to airlines on May.26 in Shanghai, it is in normal time frame , so suggest you wait patiently.
