Missing Customs declaration forms for item shipped through ebay's global shipping program

[cmarshall1]

I sold a saddle to a buyer in Australia.  I used the GSP in Erlanger, KY to ship item to Australia.  It was my understanding the GSP center would take care of necessary Customs forms for overseas shipping.  Now item is held up at Customs in Australia due to missing declaration forms.  They may destroy the item.  I've entered a resolution case with ebay and they resolved the matter by saying they would refund the buyer.  The buyer would prefer to have the saddle delivered, rather than get a refund.  How can I help get the saddle released from Customs and delivered?  I have emailed the carrier (DAIKEB) to see what can be done.  I feel so bad for the buyer; she really wants this saddle.
