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.

Consumer price index
Over the past five years to June 2022, the Darwin CPI has grown modestly averaging 2.0%, below the national average growth of 2.2%. In the 10 years prior to the slow growth, the Darwin CPI grew by an average of 2.3%, lower than the national average growth of 2.4% over the same period.
In the June quarter 2022:
- Darwin CPI increased by 2.1%, the equal highest increase of the capital cities, tied with Brisbane and Adelaide.
- the quarterly increase was driven by food and non-alcoholic beverages, in particular fruit and vegetables, due to supply chain disruptions relating to COVID-19, flooding events, labour shortages and rising freight costs.
- Darwin CPI increased by 6.0% in the year to 2021-22 (Chart 1), the equal highest increase of all capital cities, tied with Perth, which otherwise ranged from an increase of 3.9% in Sydney to 5.4% in Brisbane.
- The largest yearly price increases in Darwin were transportation (up by 15.3%) and housing (up by 11.3%). Clothing and footwear (down by 2.4 %) and communication (down by 0.6%) were the only categories to report price decreases.
Wage price index
In the March quarter 2022:
- NT WPI increased by 0.3%
- This was the lowest quarterly change of the jurisdictions, which otherwise ranged from 0.5% in Queensland to 0.6% in Tasmania, Victoria, South Australia and New South Wales.
- NT private and public sector wages increased by 0.4% and 0.1% respectively.
- NT WPI grew by 2.1% in year-on-year terms, with private sector wage growth (up by 2.2%) stronger than the public sector (up by 1.8%) (Chart 2)
- Nationally, the WPI grew by 2.2% over the same period, with public sector wage growth (up by 1.8%) below the private sector (up by 2.2%).
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 November 2021:
- NT average weekly full-time earnings (AWFTE) increased by 0.8% to $1,795 and was the second lowest year-on-year increase of all jurisdictions, ahead of New South Wales.
- NT recorded the fifth highest level of AWFTE of the jurisdictions, behind the Australian Capital Territory ($1,988), Western Australia ($1,970), New South Wales ($1,821), and Victoria ($1,812).
- the AWFTE for males in the NT increased by 0.3% to $1,919 and the AWFTE for females increased by 0.3% to $1,640 (Chart 4).
- nationally, the AWFTE increased by 2.0%, with female AWFTE increasing by 1.8% and male AWFTE increasing by 2.1%.
- 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 lump sum payments delivered to eligible employees under the Northern Territory Public Service 2021-2025 Enterprise Agreement were not captured in the ABS’ methodology for the headline WPI.
- 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.
