I have a store which regularly receives order from International addresses including Australia. But a customer tried to enter the following address and USPS does not recognize it
12 Riverdowns Cr
Helensvale,
Helensvale, 4212
QLD, Australia

I thought the problem might be QLD for Queensland but the store abbreviates it to QLD. Both my customer and myself have tried it number of times without being able to have USPS recognize the address.

Ajey you are the authority on USPS module. So I hope you will be able to shed some light on this problem,

The version is 1.3.9f and we have received many good orders from Australia. It must be this particular address that is causing the problem perhaps because of abbreviation. Please help.
