Australia Post Shipping Not calcuating Help

Hi there,

Im a real newbie at wordpress, i have condfigured the plugin and believe i have covered all areas, weights, sizes, shipping zones etc. But when i test the plugin whilst creating a order, it simply does not work out the shipping…I have obtained a API key from Australia Post…entered that…..at this stage trying to just get Australia Only shipping to show up, then would like to get international shipping to show up as well.

Message displayed is as follows:

There are no shipping methods available. Please check your address or contact us if you need any help

Would appreciate any support avaialble.
