Interpreting the data
Property sales
Sales data is compiled from the NSW Valuer Generals bulk property sales information . This data contains property sales details including postcode, contact date, settlement date, purchase price, primary purpose, and the strata lot number. The property sales data is filtered to only include residential sales, and the properties are categorised into strata and non-strata. The date of sale is based on the contract date recorded.
Strata properties are a single building or multiple buildings that have been divided into lots. Properties that are typically owned under a strata scheme include apartments, townhouses, and villas. As such, properties categorised as 'non-strata' will typically be free-standing houses, while those categorised as 'strata' will typically be apartments and townhouses.
Property rents
The NSW Government rental bond lodgement data is published monthly and includes dwelling type, weekly rent amount, number of bedrooms, and postcode data. The data was filtered to exclude properties with a rental price below $10 a week as these are not considered to be representative market rental prices. It also excludes properties that are categorised as either 'other' or 'unknown' as these may include rented rooms, garages, or car spaces. The lodgement date was used to assign the rental property a year and quarter.
The 'house' category only includes houses. The 'non-house' category includes flats/units and terraces/townhouses/semi-detached houses.
Rent assistance
To qualify for Commonwealth Rent Assistance (CRA) a person must be eligible for an income support payment, ABSTUDY, family tax benefit part A, or a veteran's service pension or income support supplement. To receive CRA, a person must be paying private rent above the applicable threshold. CRA numbers are measured at the 'recipient household' or income unit level (which is a single person, with or without children, or a couple, with or without children). This data is from the Department of Social Services housing data set and includes CRA recipient households eligible for an income support payment or family tax benefit part A.
Medians
The median value of a data set shows the exact middle value, meaning that half of the values in the data are above this value and half are below. An average is the total sum of values divided by the total count of values. Unlike the average, the median is unaffected by outliers which makes it a better measure for heavily skewed data like property prices. Despite being unaffected by outliers, the median values for NSW are heavily skewed by the higher volume of property sales and rents across Sydney when compared to the rest of NSW. For example, this is observable in the higher median weekly rent for non-houses compared to houses, which is due to the eastern suburbs of Sydney accounting for a large proportion of the non-house rent data while house rent data is spread more evenly across the state. Due to a low volume of strata properties generally, Barwon has had multiple quarters without enough strata property sales to produce a median for.
The presented median values are representative of the typical property sale price or rental price for an area and are heavily dependent on whatever that typical property looks like. Location is not the only defining feature of a property. Features such as distance to amenities, size, and number of bedrooms differ from place to place and also impact the median price or rent.
Methodology
Weighted median
A weighted median of the values for property sales and rental costs is presented for each electorate and region. The weights used to calculate these medians were assigned using a postcode to state electoral district (SED) population-weighted correspondence, where the postcode data is assigned a weight based on the percentage of the population in that postcode which lives in the SED.
Inflation
The property sale and rental price data in the dashboard is presented as both inflation adjusted and in nominal values. As the price of goods and services increase over time the relative buying power of a currency decreases. The inflation adjusted prices show the price of housing over time in Q4 2025 dollars, adjusted for this change in buying power. Inflation adjustments were made using the RBA's quarterly trimmed mean inflation values. The price changes in the interactive tables and maps are based on nominal values.
Percentage of households receiving rent assistance
Rent assistance data is published for statistical areas level 2 (SA2s). The Research Service produced electorate-level estimates using an SA2 to SED population-weighted correspondence. Transport for NSW publishes occupied private dwelling projections for small areas called transport zones (TZs). The Research Service used occupied private dwellings data to derive estimates of the number of households in each electorate using a TZ to SED population-weighted correspondence. This data was used to calculate the percentage of households receiving rent assistance.
The rent assistance data presented in the map was prepared by performing a SA2 to postcode population-weighted correspondence. The percentage of households receiving rent assistance was estimated by also corresponding transport zones to postcodes and using these values as an estimate for households per postcode.
