The Survey of Income and Housing (SIH) collects data from households across Australia to measure levels of housing occupancy and costs and how these change over time.
- Around two thirds (66%) of Australian households owned their own home with or without a mortgage, a decrease from 68% in 2015–16.
- Almost one third (32%) of Australian households rented their home in 2017–18, an increase from 30% in 2015–16.
- Average weekly housing costs increased to $484 for owners with a mortgage (up $15 per week from $469 in 2015–16) and remained relatively stable for the other major tenure types ($53 for owners without a mortgage, $366 for renters).
- Households continued to spend 14% of their gross weekly income on housing costs (owners with a mortgage spent 16% and renters spent 20%).
- The average number of persons per household remained stable at 2.6, and the average number of bedrooms per dwelling was unchanged at 3.2.
- Applying the Canadian National Occupancy Standard for housing utilisation, almost one in twenty (4%) of Australian households required at least one additional bedroom to meet the requirements of the household, while more than three quarters (79%) of households had at least one bedroom spare.
- One in five households (20%) owned one or more residential properties other than their usual residence. Of those that owned other residential property, almost three quarters (71%) owned a single property, while one in twenty (5%) owned four or more properties.
- More than half (55%) of recent first home buyers were households with a reference person aged under 35 years.
