Temando has nothing to do with Australia Post or StarTrack. 

As I said, they are a courier broker and also a client of StarTrack as well as a number of other courier companies.

If you want to find out more about them look it up for yourself.

There are a number of courier brokers who are just that....brokers who will find a well priced courier service for the customers needs.

They are not agents for AP or StarTrack.

Depending on their turnover it is possible that they are getting better rates and will pass it on to their customers.
