The long-term growth in Australian residential property becomes particularly striking when you look back several decades.
In Sydney, historical figures show just how dramatically housing values have changed. A house that cost around $18,700 in 1970 had risen to approximately $76,500 by 1980. By 1990, the figure was around $184,600, increasing to approximately $312,000 in 2000 and $575,900 by 2010.
While different data series use different measures — including median sale prices, median values and price indexes — the long-term direction is clear: Sydney residential property values have increased substantially over successive decades.
The Australian Bureau of Statistics provides historical housing and price data, while Cotality (formerly CoreLogic in Australia) publishes ongoing analysis of residential property values and market conditions.
How have Australian house prices changed over time?
Australia's property market has not moved upwards in a straight line. There have been periods of rapid growth, slower conditions and falling values, influenced by factors including interest rates, credit availability, population growth, housing supply, employment and broader economic conditions.
Over the longer term, however, residential property has experienced substantial capital growth.
That long-term perspective is important. Looking at property prices over 20, 30 or 50 years can produce a very different picture from looking at a single year or market cycle.
What was the average house price in Sydney in 1990?
One of the questions people frequently ask when looking at historical property prices is how much a Sydney house cost in 1990.
Historical figures put the Sydney house price at approximately $184,600 in 1990, compared with around $76,500 in 1980.
By 2000, the figure had increased to approximately $312,000.
Those numbers help illustrate how significant the change in Sydney residential property values has been across a generation.
Sydney house prices: 1970 to 2010
Sydney house prices have increased substantially over the past several decades. In 1970, the historical house price was approximately $18,700. By 1980, this had risen to around $76,500, and by 1990 to approximately $184,600. In 2000, the figure had reached around $312,000, increasing further to approximately $575,900 by 2010.
These historical figures illustrate the scale of Sydney's long-term property price growth, although comparisons between periods should be treated as indicative because the measures and methodologies used to report housing prices have changed over time.
Historical figures should be treated as indicative because methodologies and measures used in housing-price datasets have changed over time. Median sale price, average price and estimated property value are not necessarily interchangeable.
For example, historical ABS releases report median prices of established house transfers and separate results by capital city. That distinction is important when comparing figures from different periods.
What has happened since 2010?
Sydney's property market has experienced several distinct cycles since 2010 rather than uninterrupted growth.
Periods of strong appreciation have been interrupted by tighter credit conditions, interest-rate changes and market corrections. This is why extrapolating a historical growth rate indefinitely — for example, assuming a particular percentage increase will continue every year for another 20 years — can be misleading.
Current market data also demonstrates that different segments can behave very differently. Cotality's September 2026 Housing Chart Pack, for example, reported that Sydney's upper-quartile house values were 10.7% below their peak, illustrating that even within a long-term growth story there can be significant shorter-term declines.
What does long-term house-price growth mean for property owners?
Historical house-price growth is interesting, but it should not be confused with the value of an individual property.
Two properties in the same suburb can perform very differently because of their land, location, condition, accommodation, planning controls, development potential, views, aspect and other characteristics.
The purpose and date of a valuation also matter. This is particularly relevant when an owner needs to establish what a property was worth at an earlier point in time for purposes such as Capital Gains Tax, an estate or another retrospective assessment.
Wills Property provides independent property valuations across Sydney, including current and retrospective valuations for Capital Gains Tax, probate and deceased estates, SMSFs, family law, stamp duty and related-party transactions.
