Hello,
In relation to the above link I have sent a message to AustPost requesting they answer you but this is starting to linger too long and pretty soon my client will start making threats for me to deliver.
In that case you can use the AuPost shipping plugin V2 with the "group package" option set to NO.
Can we please look into when the AustPost (version 1) plugin does not currency convert on the postage amount.
The solution will probably be to directly add the lines :
if(hikashop_getCurrency() != 6)
$finalRate->shipping_price = $currencyClass->convertUniquePrice($finalRate->shipping_price, 6, hikashop_getCurrency());
Just after :
foreach($rates as $finalRate){
trough the "aupost.php" file of your Aupost plugin.
