Yeah that just means it's on its way. It has left China.
For example when it reaches Australia, it will then read something like this:
Timing Site Status
2009-07-22 13 SHANGHAI Posting
2009-07-22 13 25 Despatch from Sorting Center
2009-07-22 19 SHANGHAI Arrival at Sorting Center
2009-07-22 20 SHANGHAI Despatch from Sorting Center
Status: Arrived at Commonwealth of Australia (something along these lines)
Status: Handed over to Customs

Then, over to the post office; you usually get it the next day.
