The updated Australia Post Shipping plugin is now available for Versions 4.0, 4.1 and 4.2 and incorporates the latest improvements and some new features. In previous versions there was some problems with the information returned from Australia Post not being unique which mean it was hard for the customer and store owner to understand the service options. This plugin re-codes the information received from Australia Post in an easy to read and understandable format, for example:
-  Australia Post - Regular Post Extra Large Satchel (Calculated Cost)
-  Australia Post - Regular Post Extra Large Package (Calculated Cost)

There are also additional configure options to only show the Lowest price services to the customer, ignore specific services as well as allowing the customer to select the shipping options: Extra Cover Insurance, Signature on Delivery and Email Track Advice. Online demos are also available for all versions.
