Release Information

In Australia, House Price Indices statistics are compiled by the Australian Bureau of Statistics. The suite includes:

  • Residential Property Price Index (RPPI)
  • Established House Price Index (HPI)
  • Attached Dwelling Price Index (ADPI)

The RPPI is calculated on the reference base 2011-12=100.0 for each of the eight capital cities as well as a weighted average of them. The capital city indexes measure price movements over time within the eight Greater Capital City Statistical Areas (GCCSAs).

The HPI measures the price change in all established detached houses on their own block of land.

The ADPI measures the price change of attached dwellings within the eight GCCSAs. Dwellings in scope of the index are flats, units and apartments; semi-detached, row and terrace houses.


  • Measurement: Fixed-base index relative to 2011-2012 (Index 2011-12=100)
  • Adjustment: Not seasonally adjusted (NSA)
  • Native frequency: Quarterly
  • Start date: Uniformly 2002Q1
  • Geo coverage: 
    • National-equivalent (IAUS_CAP)
    • 8 metropolitan areas (IAUS_M^^^)


  • HPI, Jul2003-Jun2004 - 1986 to 2013
  • HPI, 1989-1990 - 1986 to 2005

The ABS employs a stratification approach to compile the RPPIs. The stratification approach separates the total sample of residential properties into a number of sub-samples or strata. Dwelling transactions are stratified by dwelling type, long term median price and Socio-economic Index for Areas score. Each quarter, the strata are re-valued by applying a price relative (i.e. the current period median price of the stratum compared to the previous period median price of the same stratum) to the value of the dwelling stock for that stratum to produce a current period stratum value. The current period values of each stratum are then summed to derive the current value of the total dwelling stock in the capital city. Index numbers are subsequently derived from the total values.

Moody's Analytics supplements

For the "established houses" index, for each of the nine geos, we produce a seasonally adjusted counterpart using the U.S. Census Bureau's X-13ARIMA-SEATS program.

Estimates for the two most recent quarters of the established house price index series are preliminary and are subject to revision

The price indexes, and therefore the percentage changes, for the two most recent quarters are subject to revision as more complete data sets are obtained.
