Google promotes any product that pays their fees for doing so, no questions asked. This topic may be enlightening, and subsequently @Fred123’s efforts to get the google presence removed.
You already have your answer on your account statement, but for others who may be tempted to order products off shore, regardless of what refund one might get if any, since product was purchased in foreign currency the refund will also be in that currency. It is rare the purchase and credit amounts will be the same in $AUD because each transaction is made using the exchange rate of the moment. During a day it is common for $AUD rates to vary 1% and 5% across any week is not uncommon.
A 100% refund could put extra or fewer $AUD in one’s account than the original charge, so foreign purchases have a bit of currency risk as a percentage of the transaction; depending on the value of the transaction it could be from pennies to meaningful amounts.
