Prices and wages statistics are based on data reported by the Australian Bureau of Statistics (ABS). For the latest available data and analysis, see the Department of Treasury and Finance’s Consumer price index, Wage price index and Average weekly full-time earnings economic brief.

In the year to March 2019, the Darwin consumer price index (CPI) increased by 1.0% (Chart 1). The main categories that recorded a yearly increase were tobacco and alcohol (mainly tobacco), transportation (mainly fuel), financial services (mainly other financial services), health (mainly medical and hospital services), and education (mainly secondary).
Darwin recorded the lowest yearly CPI increase of all capital cities. The change in other capital cities ranged from an increase of 1.2% in Perth to 2.5% in Hobart. Table 2 shows the quarterly and year-on-year changes in the Darwin CPI groups.
Each group in CPI is given a weighting depending on its relative importance to household expenditure, which is outlined in Table 1.
Table 2 shows the quarterly and year-on-year changes in the different components in the basket of goods. The category of alcohol and tobacco recorded the largest increase in year-on-year terms, up 7.7% and transport was up 3.6%. The categories that recorded the largest price declines in 2018 were communication (mainly telecommunications), which has been declining since 2014, and housing (mainly rent), down 4.6% and 1.3%, respectively.
In the March quarter 2019, the Northern Territory (NT) wage price index (WPI) increased by 0.5%, with public sector wages increasing by 10.4% and private sector wages increasing by 0.5%. Alongside Victoria, Tasmania and the Australian Capital Territory, this was the highest quarterly increase in WPI of the jurisdictions, with the lowest being 0.3% in Western Australia.
In the year to March 2019, NT WPI grew by 2.0% (Chart 2). Public sector wage growth was stronger (up 2.8%) than the public sector (up 1.5%). Nationally, WPI grew by 2.2% over the same period, with public sector wage growth (up 2.4%) stronger than the private sector wage growth (up 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. Even in industries where there are a higher proportion of employed women, such as in education and training, and health care and social assistance, males are still earning a higher median weekly income, as they are more likely to hold senior positions than females. The income gap of full-time working women in the NT is wider than the national figures. However, the NT has a more equal workforce gender distribution across most industries compared to Australia (Chart 3).
According to ABS, in the year to November 2018, the NT average weekly full-time earnings (AWFTE) decreased by 1.1%, which was the only year-on-year decrease of all jurisdictions. However, the NT recorded the third highest level of AWFTE of the jurisdictions, behind the Australian Capital Territory ($1,842) and Western Australia ($1,833). In the year to November 2018, the AWFTE for males in the NT decreased by 2.9% while the AWFTE for females increased by 4.1% (Chart 4). Nationally, the AWFTE increased by 2.5% over the same period, with female AWFTE increasing by 3.4% and male AWFTE increasing by 2.2%.
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.
