Electricity fell 7.5%, the strongest quarterly fall in the history of the series, dating back to 1980. The fall was due to a $600 household electricity credit introduced on 1 November by the Western Australian (WA) government, resulting in a significant fall in electricity prices in Perth (-66.7%).
A rise of 0.7% in the series new dwelling purchase by owner occupiers partially offset the fall. House builders passed through increases in project home prices and reductions in the value of promotional offers in response to higher demand. The rise was partially offset by the impact of HomeBuilder and state-based grants in WA and Tasmania. Without these grants, new dwelling purchase by owner occupiers would have risen 1.3% (see the following graph).
Rents (+0.1%) recorded a small rise following two quarters of falls. Rental market conditions are improving across most capital cities, consistent with falling vacancy rates and rising advertised rates. However, rent freezes for existing tenants remain in place in some states and territories.
Over the past twelve months the group fell 0.9%, which is the most significant fall since 1998. The fall was driven by utilities (-6.6%) and rents (-1.3%).
In seasonally adjusted terms, the group fell 0.6%. The main contributor was electricity (-7.7%).

The following graph shows the impact of HomeBuilder and the WA and Tasmanian state-based housing construction grants on the CPI series ‘new dwellings purchase by owner occupiers’ in the December 2020 quarter. The graph shows the impact before and after the application of these grants in the CPI.

Furnishings, household equipment and services group (+3.4%)

Health group (+1.3%)

Transport group (+0.9%)

Rises of 1.8% in motor vehicles and 4.5% in urban transport fares were the main contributors. Increasing demand for cars combined with supply disruptions resulted in price rises and reduced prevalence of typical end of year run-out sales. The rise in urban transport fares was due to the cessation of discounts offered on Sydney off-peak fares.
Over the past twelve months the group fell 4.6%. The main contributor was automotive fuel (-16.7%).
In seasonally adjusted terms, the group rose 1.0% this quarter. The main contributor was motor vehicles (+2.2%).

The Consumer Price Index (CPI) rose 0.9% in the December quarter in original terms and 0.8% in seasonally adjusted terms.

At the All groups level, seven capital cities saw rises ranging from 0.6% in Darwin to 1.5% in Melbourne for the quarter. Perth was the only exception, recording a fall of 1.0% due to the $600 household electricity credit introduced by the state government from 1 November.
Tobacco rose in all capital cities, due to the annual excise tax increase of 12.5% and the bi-annual excise tax increase based on Average Weekly Ordinary Time Earnings (AWOTE) indexation, both applied on 1 September 2020.
Furnishings, household equipment and services rose in all capital cities due to child care, following the cessation of free child care on 13 July. Out-of-pocket expenses have now returned to pre-COVID levels in all capital cities. Melbourne recorded a higher rise in the December 2020 quarter due to the increase in the out-of-pocket expenses for child care as attendance levels returned following stage 4 lockdown in the September quarter.
Health rose in all capital cities due to increases in private health insurance premiums on the 1 October 2020, following a six-month price freeze.
Annually, the CPI rose 0.9%. At the All groups level, six capital cities saw annual rises ranging from 0.8% in Sydney and Hobart, to 1.3% in Melbourne. Darwin was flat and Perth recorded a fall of 0.1%.

Spotlight: CPI exclusion-based measures

Each quarter, the ABS produces a range of CPI exclusion-based measures, which remove selected components from the CPI basket. Typically, the removed components have volatile price changes and/or a pronounced seasonal pattern. These exclusion-based measures can help distinguish short term price fluctuations that impact the quarterly CPI movement, providing additional insights into the general direction of medium-term inflation.

An example of a CPI exclusion-based measure is ‘CPI excluding alcohol and tobacco’, where annual increases in the federal excise tax have had a significant effect on tobacco prices each year.

COVID-19 has brought about new challenges in measuring the CPI. For the December 2020 quarter, additional CPI exclusion-based measures have been produced to those previously available in Table 8 of this release. The additional exclusion-based measures, presented in Table 1 of this article, demonstrate some of the temporary impacts of COVID-19 on the December quarter CPI.

Table 1 shows both the quarterly and annual movements for selected exclusion-based measures and can be used to compare to the headline CPI. For example, when excluding child care from the CPI, the quarterly movement is 0.5 per cent compared to 0.9 per cent for the published CPI. This highlights the impact that the unwinding of free child care has had on the December 2020 quarter CPI movement.

How to calculate exclusion-based series

Points contributions, available in Table 12 of the CPI release, can be used to calculate exclusion-based measures. The sum of the points contributions of all lower level components equals the overall CPI index value. The points contribution of selected components can then be excluded and the CPI re-calculated.

Measuring the quarterly price change that would occur when excluding a CPI component is calculated by subtracting the points contribution of the CPI component from the CPI index number in each quarter and then calculating the percentage change between the resulting indexes. ‘CPI excluding electricity’ series has been used as an example in Table 2.

Table 2: Calculating exclusion-based measure example
	Dec-20	Sep-20
All Groups index	117.2	116.2
Electricity Points Contribution	3.0	3.3
All Groups minus Electricity	114.2	112.9
Quarterly movement (114.2-112.9)/112.9*100 (%)	1.2

Table 2 shows that prices of all items other than electricity increased by 1.2 per cent on average between the September 2020 and December 2020 quarters.

Spotlight: Underlying inflation measures

The Trimmed Mean and Weighted Median provide important insights into underlying inflation and the health of the Australian economy. These measures are derived from the Consumer Price Index (CPI) by removing atypical movements from the quarterly CPI, and recalculating a quarterly movement. Full details of the methods can be found in Explaining the Trimmed Mean and Weighted Median.

The COVID-19 pandemic has resulted in some extremely large price changes, such as the provision and subsequent discontinuation of free childcare for Australian families. The underlying inflation measures reduce the influence of these large price movements, and thereby provide a measure of medium-term inflation.

As discussed in Update to measuring the CPI in the December 2020 quarter, prices for International holiday travel and accommodation were imputed during the December quarter to have a quarterly change equal to that of the headline CPI, rather than being measured. Following the 2020 annual re-weight this series contributes a weight of 0.1% to the CPI. Additionally, Domestic holiday travel and accommodation returned to normal price collection after being imputed in the September quarter, contributing a weight of 2 per cent to the CPI.

Imputing price movements for these series presented the challenge of how they should contribute to the underlying inflation measures. The two options considered by the ABS were:

Use all 87 CPI series, including the two imputed series, in the calculation of the Trimmed Mean and Weighted Median.
Exclude the two imputed series and calculate the Trimmed Mean and Weighted Median using the remaining 85 series.

In order to maintain consistency in the methods used, the ABS selected option 1 for the official measures presented on the Main Features page of the December CPI release, as per the June and September quarters. In this article, Table 1 presents the quarterly and annual movements for both options 1 and 2.

Table 1. December 2020 quarter Trimmed Mean and Weighted Median, including and excluding imputed series
	Including imputed series (Option 1)		Excluding imputed series (Option 2)
	Quarter (%)	Annual (%)	Quarter (%)	Annual (%)
CPI	0.9	0.9	0.8	1.0
Trimmed Mean	0.4	1.2	0.4	1.4
Weighted Median	0.5	1.4	0.4	1.4

Overall, excluding these two series from the Trimmed mean and Weighted median calculations (option 2) makes little difference to the quarterly and annual movements in the December quarter.

Chart 1 shows that when included in the calculations, both imputed series contribute to the Trimmed Mean, with Domestic holiday travel and accommodation also falling as the Weighted Median. Chart 2 shows the calculation of the two measures when the two imputed series are excluded.

Use of price indexes in contracts

Price indexes published by the Australian Bureau of Statistics (ABS) provide summary measures of the movements in various categories of prices over time. They are published primarily for use in Government economic analysis. Price indexes are also often used in contracts by businesses and government to adjust payments and/or charges to take account of changes in categories of prices (Indexation Clauses).

Use of Price Indexes in Contracts that sets out a range of issues that should be taken into account by parties considering including an Indexation Clause in a contract using an ABS published price index.
