A) If the Australian dollar appreciates, the RBA doesn't care, unless its an abnormal increase, it will intervene
B) Increase in skilled immigration Program = Healthy
C) A Less Budget Surplus = expansionary stance, will mean that there is a stimulation in the economy. Tighter Monetary Policy is possible, because the budget may perhaps be pro-cyclical in the future.
D) Consumers are faced with water shortages. This increases the cost for consumers. Unless the Water inflation is extremely high, the RBA Is unlikely to intervene. It is a volatile event and only affects consumers, not businesses. Example was severe droughts and the RBA did not increase cash rates because of these things. IT WILL intervene if there is a serious consequence to inflation as a whole.
= C is the only contractionary answer possible/ most likely
