Currency rates are updated daily from published bank exchange rates and include foreign exchange fees. These rates are used to convert your international currency rewards to Australian dollar rewards when they are first displayed in your account. Providing the foreign amount is not subsequently adjusted by the store the initial conversion amount will be final as per the date of the transaction. If, however, the store subsequently adjusts the transaction amount the current exchange rate on the date of the adjustment will be used to redetermine the Australian dollar conversion amount.
