The stability (stationarity) of real interest rates and surveys of expected inflation in Australia is analyzed over the period 1993(10) to 2001(10). We find that the real yields on Australian 2-, 5-, and 10-year bonds are stationary in levels whereas the real overnight cash and the bank-accepted bills (BABs) 90-day real rates are stationary subject to structural breaks occurring in September 1994 and October 1994, respectively. These breaks were identified by applying tests proposed by Nunes et al. [Oxf. Bull. Econ. Stat. 59 (1997) 435]. An application of the Nunes test to the surveyed expected inflation series points to a structural break in this series in January 1998. Our results indicate that while real long-term bond yields in Australia are relatively stable, short-term yields and expected inflation are susceptible to domestic policy changes and international influences.
