The article is based on empirical data from Australian Economy. It made an attempt to evaluate the success of Reserve Bank of Australia (RBA) in controlling inflation by aggressively using cash rate. The main objective of the research is to find out the relationship of RBA's monetary policy with Taylor Rule; whether it follows the Taylor Rule mechanically or uses a different form (e.g. forward looking) or depends on other factors as well. Other models have been used for estimation and the results are analyzed subsequently. The evidences from the test results suggest the successful implementation of interest rate rule by the Reserve Bank to stabilize the inflationary pressure in terms of forward looking perspective. The monetary policy has evolved in the last few decades towards a new concept-inflation targeting. Many countries are already practicing inflation targeting as a tool for monetary policy. New Zealand was the first country that introduced inflation targeting in 1990. Till then it dispersed to other countries, i.e. Canada, UK, Sweden, Australia, Finland etc. The basic idea of inflation targeting is that, central bank adjusts the short term interest rate in such a way that ensures the projections of inflation and other variables satisfy the target criterion. Though the objective of inflation targeting is to stabilize the inflation around the target, it also takes into account the importance of output gap by allocating some weight onto it. The inflation targeting is based on the following characteristics: Numerical Inflation Target: Central bank usually specifies the target as a range rather than point estimation. Inflation-Forecasting-Targeting: The decision making process is stated as inflation-forecasting-targeting. Transparency & Accountability: The overall process must be transparent and central bank must be accountable for the consequences. Usually, in the inflation targeting regime, central bank makes public announcements about any changes in policy indicating both current inflation and expected future inflation states and steps needed to keep inflation in track. The desired level of target inflation actually achieved gradually over a period than in one instance. The stability is linked with the concept "Price Stability", and this price stability does not refer to zero inflation rather it is closer to a low level (i.e. 2%) annual rate of price changes. The target price level need not remain constant indefinitely, but could be allowed to drift upward in a predetermined way over time (Goodhart and Vinals, 1994; Svensson, 1996).
