The prices and wages section compares the difference between the rate of inflation and the average household income, and how this affects the cost of living in the Northern Territory (NT). Analysis is provided on Darwin's consumer price index (CPI), the NT’s wage price index (WPI) and average weekly earnings (AWE). CPI reports on the changes in price of categories such as housing, food and non-alcoholic beverages, recreation and culture, alcohol and tobacco, transportation, furnishings, household equipment and services, financial and insurance services, health, communication, clothing and footwear, and education. WPI measures changes in the price that employers pay for labour, arising from market factors by both the private and public sectors of employment. AWE measures the level of average earnings in the NT.

Key facts
Consumer price index
- Over the past five years to 2020-21, the Darwin CPI has grown modestly averaging 0.8%, below the national average growth of 1.6%. However, in the 10 years prior (2006-07 to 2015-16) to the slow growth, the Darwin CPI grew by an average of 2.7%, higher than the national average growth of 2.5% over the same period.
- Each group in the CPI is given a weighting depending on its relative importance to household expenditure, which is outlined in Table 2.
In the September quarter 2021:
- Darwin CPI increased by 1.5%, the largest increase of the capital cities.
- the quarterly increase was driven by housing due to price increases for new dwelling purchases, transportation due to increases in the price of fuel, and insurance and financial services due to the removal of the Territory Home Owner Discount (THOD).
- Darwin CPI increased by 3.5% in the year to September 2021 (Chart 1), the strongest yearly CPI result of all capital cities which otherwise ranged from an increase of 1.9% in Adelaide to 2.9% in Brisbane.
- the largest yearly price increases in Darwin were furnishings, household equipment and services (up by 6.6%) and alcohol and tobacco (up by 6.2%). Communication (down by 1.7%) and clothing and footwear (down by 1.6%) were the only categories to report price decreases.
Wage price index
In the September quarter 2021:
- NT WPI increased by 0.9%
- This was the second highest quarterly change of the jurisdictions, behind the Australian Capital Territory and Tasmania (up by 1.0%). Victoria, Queensland, and New South Wales also rose by 0.9%.
- NT private and public sector wages both increased by 1.0%
- NT WPI grew by 1.9% in year-on-year terms, with public sector wage growth (up by 2.1%) stronger than the private sector (up by 1.8%) (Chart 2)
- Nationally, the WPI grew by 1.7% over the same period, with public sector wage growth (up by 1.5%) below the private sector (up by 1.8%).
Based on the 2016 Census data:
- the median total weekly personal income of women who are working full time in the NT is less than the median for males in the same industry, across most industries
- the income gap of full-time working women in the NT is wider than the national figures
- NT has a more equal workforce gender distribution across most industries compared to Australia (Chart 3).
Average weekly earnings
In the year to May 2021:
- NT average weekly full-time earnings (AWFTE) increased by 0.5% to $1,801 and was the lowest year-on-year increase of all jurisdictions
- NT recorded the fourth highest level of AWFTE of the jurisdictions, behind Western Australia ($1,962), the Australian Capital Territory ($1,952) and New South Wales ($1,822)
- the AWFTE for males in the NT increased by 0.7% to $1,929 and the AWFTE for females increased by 0.3% to $1,637 (Chart 4)
- nationally, the AWFTE increased by 2.2%, with female AWFTE increasing by 2.4% and male AWFTE increasing by 2.0%.
Explanatory notes
- Prices and wages statistics are based on data reported by the Australian Bureau of Statistics (ABS).
- Inflation is a key economic indicator that measures the change in the general level of consumer prices over a given period of time. ABS measures inflation in the economy through changes in CPI.
- CPI measures the price of a representative basket of goods and services in each Australian capital city. Each group in CPI is given a weighting depending on its relative importance to household expenditure, which is outlined in Table 1.
- The ABS introduced the 17th series of weighting pattern of the CPI series due to incorporating the results from the Household Expenditure Survey 2015-16. The introduction of the new CPI series has resulted in a break in the time series regarding components percentage point contributions to the CPI growth rates.
- The ABS WPI measures the influence of market factors on the price employers pay for a standard unit of labour. To establish a standard unit of labour for the index, the ABS holds the quantity and quality of labour services constant by excluding changes in the composition of the labour force, hours worked and changes in characteristics of employees (such as productivity) from the index.
- The ABS average weekly earnings (AWE) survey is designed to measure the level of average earnings in Australia at a point in time. Movements in average weekly earnings can be affected not only by changes in the level of earnings of employees but also changes in the overall composition of the labour force. This relates to variations in the occupational distribution within and across industries, distribution of employment between industries and proportion of male and female employees.
- AWE are not comparable with those for the WPI. They have different purposes and concepts and use different sample selection and estimation methodology. The WPI is a price index to measure changes over time in the price of wages and salaries and it is unaffected by changes in the quality and quantity of labour services. AWE measures the level of average earnings and, in addition to changes in the price of labour, is affected by changes in hours worked and by compositional changes.
