Shipping from Guangdong Province to Australia

I got an email this morning that my parcel was posted around 10pm 24/11/2013 local time. My tacking number isn't on the system yet. Why is that? Tracking code is RQ192603988SG
This is the re- send of an order I placed 8 weeks ago. I really like to know if its coming before I place dispute with PayPal by 10 December. Thank you.
