Amendment to Consumer Price Index. If either:
(a) the Consumer Price Index ceases to be published quarterly; or
(b) the method of calculation of the Consumer Price Index substantially alters, then the Consumer Price Index is to be replaced by the nearest equivalent index and any necessary consequential amendments are to be made. That index and those amendments are to be determined by agreement between the parties or, if the parties do not agree, by the Australian Bureau of Statistics or a nominee of the Australian Bureau of Statistics (acting as an expert and not as an arbitrator), whose decision is binding and conclusive.
