Key issue
In the 12 months to March 2022, the Consumer Price Index (CPI) increased by 5.1%, the highest annual rise reported since the introduction of the GST in 2000.
The cost of living can be analysed through various indexes produced by the Australian Bureau of Statistics (ABS).
Recent increases in the cost of living indexes were primarily driven by price increases in transport and housing.
Cost of living measures
Price rises in the cost of essential goods such as
housing, utilities, petrol, and groceries often raise concerns around the cost
of living in Australia. To assess whether living costs have increased over a
period, a broad range of household costs need to be considered, as well as the
proportion of household expenditure allocated to different expenditure items.
The ABS publishes several measures that can assist in understanding changes in
the cost of living.
The Consumer Price Index (CPI)
The CPI measures changes in the price of a basket
of goods and services over time, designed to be representative of average
household expenditure. It is calculated using price changes within each capital
city only and cannot be used to compare differences between regions. The
CPI does not include the cost of buying established dwellings but includes
rents, the cost of new dwellings (excluding value of land) and major
alterations and additions to dwellings. Mortgage repayments are not included in
the CPI. The CPI is often referred to as the measure of inflation, or headline
inflation.
- During the most recent 2-year period (March 2020
to March 2022) the CPI rose 1.1% in the first 12 months, but 5.1% in the
second. This rise of 5.1% was the highest annual rise reported since the
introduction of the GST in 2000.
Underlying inflation
The ABS produces 2 key measures of underlying
inflation – the ‘trimmed mean’ and the ‘weighted median’. These measures are
designed to reduce the impact of irregular price changes by removing changes in
the most volatile categories such as fuel. Over the long-term, the ‘all groups
CPI’ trend will be similar to both the ‘trimmed mean’ and ‘weighted median’.
- In the most recent year (March 2021 to March 2022) the ‘trimmed
mean’ rose by 3.7% and the ‘weighted median’ 3.2%, as opposed to the ‘all
groups CPI’ of 5.1%.

Selected Living Cost Indexes (SLCI)
The ABS calculates cost of living indexes for 4
distinct household types defined by their principal source of income. Each
household type LCI is determined with reference to their individual spending
pattern and they are only available at an Australia-wide level. The principal
difference between CPI and LCIs is that LCIs include mortgage interest charges
but do not include new house purchases, while the CPI includes the cost of new
house purchases but does not include mortgage interest charges.
Consumer Price Index over time
While it fluctuated over the 20 years preceding
the pandemic (March 2000 to March 2020) the annual CPI rose at an average
annual rate of 2.6%. During the 2-year pandemic period (taken to be March
2020 to March 2022) the CPI rose 1.1% in the first 12 months, but 5.1% in the
second.
This annual increase was the largest since the
introduction of the GST which led to an annual increase of around 6% for the
4 consecutive quarters from September 2000. Prior to this, CPI had stayed
above 5% for 17 years from September 1972 through to September 1989, except for
a brief period when the introduction of Medicare (in 1984) significantly decreased
the price of health care for the consumer.
High commodity prices and growing domestic demand
in the latter stages of the global resources boom saw annual inflation rise to
a peak of 5.0% in September 2008. Inflation then decreased dramatically
following the onset of the global financial crisis with quarterly deflation of
-0.3% in December 2008. By September 2009, annual inflation had reached a low
of 1.2%.
A decrease in CPI occurred in the June 2020 quarter
when it fell by 0.3%, 3 months into the pandemic period, principally due to the
Australian Government subsidy of childcare costs.
As the CPI measures the cost to the consumer,
government subsidies can have an impact on prices paid. During the pandemic,
the Australian Government made childcare services free for families from 6
April to 12 July 2020. Consequently, the price of childcare for families
dropped 95% in the June 2020 quarter but rose 1380% in the September 2020
quarter and then 38% in the December quarter 2020 when it returned to the
longer-term trend. As childcare accounted for 1.2% of household expenditure at
the time, the impact on total CPI was to record a 0.3% decrease for the year to
June 2020.
Consumer Price Index by group
At the group level, the biggest increases in the
last 12 months were for Transport (13.7%) and Housing (6.7%). The increase
in Transport costs was a significant departure from the pre‑pandemic
long-term trend of an average annual increase of only 1.8%.
Two groups for which costs decreased in the same
period were Clothing and Footwear down 1.5%, and Communication down 0.8%.

Consumer Price Index by expenditure class
CPI groups are sub-divided into 87 expenditure
classes. Expenditure classes are the lowest level groupings of similar goods or
services for which price indexes are reported.
In terms of the recent annual rise in their price
to the consumer, the top five expenditure classes were: Automotive Fuel; New
Dwelling Purchase by Owner-Occupiers; Vegetables; Beef and Veal; and Other
Non-durable Household Products (includes items such as light globes, toilet
paper, tissues, garbage bags, batteries).

Automotive Fuel
The price of Automotive Fuel fluctuates
considerably (Figure 2) and in the last 5 years has ranged between dropping
by 19% over a quarter (June 2020) to rising 11% (March 2022). Heavily dependent
on global oil prices, the recent March 2022 quarter rise was attributed to an
oil price shock caused by the Russian invasion of Ukraine in February 2022,
paired with an ongoing easing of COVID-19 restrictions which strengthened
global demand.
All CPI indexes are based on final cost to the
consumer. From 30 March 2022 until 28 September 2022, the fuel excise rate will
be reduced by 22.1 cents per litre. This would represent a 12% reduction in the
cost of petrol across the 2 quarters (June and September 2022).

change in automotive fuel price index, March 2017 to March 2022

(Canberra: ABS, 2022).
New Dwelling Purchase by Owner-Occupiers
In the March 2022 quarter, continuing strong demand
for housing construction enabled builders to pass through increases in costs
for both materials and labour. Fewer grant payments this quarter from the
Australian Government’s HomeBuilder program and similar state-based housing
construction programs also contributed to the rise in prices for the consumer.
Vegetables
Vegetable prices rose due to COVID-19 related supply
chain disruptions and the high costs of transport and fertiliser. Flooding in
production areas of NSW and Queensland also disrupted supply in
early March, placing additional pressure on vegetable prices late in the
quarter.
Beef and Veal
Meat and seafood prices have risen due to herd
rebuilding in response to favourable weather conditions, reducing supply.
Supply chain disruptions and high transport costs also contributed to the rise.
Other Non-durable Household Products
Grocery item prices have increased as supermarkets
passed through supplier cost increases and reduced discounting activity in
response to supply disruptions. According to the Reserve Bank of Australia,
retailers have become more willing to accept price increases from their
suppliers due to the broad-based cost increases their suppliers have faced,
including for inputs, shipping, and packaging.
Other expenditure classes of interest
Electricity and gas
Prior to the pandemic the long-term trend in both
household electricity and gas prices was similar at 6.0% and 5.9% per year,
respectively. During the pandemic, electricity prices fell 11.2% in the first
year and grew 3.5% in the second. Gas prices fell 1.4% in the first year but
rose in the second year by 7.4%.
In the December 2020 quarter, the Western
Australian Government introduced a $600 household electricity credit, resulting
in a fall in electricity prices in Perth of 66.7%. In the March 2021 quarter,
prices for utilities fell owing to declines in regulated electricity prices plus
the introduction of state government rebates.
In the March 2022 quarter, Gas and Other Household
Fuels’ prices increased by 4.4%, driven by a 10.9% rise in Melbourne largely
due to annual price reviews that factored in rising wholesale and network
costs.
Rents
In the June 2020 quarter rents declined for the
first time in 45 years. The supply of properties available for long-term rental
had increased since the outbreak of COVID-19 and the introduction of travel restrictions
encouraged some landlords who were previously supplying short-term holiday
accommodation to put their properties on the longer-term rental market. Around
5% of residential tenants successfully negotiated rent reductions in the
quarter. In the March 2022 quarter, rents increased by 0.6% which was the
highest quarterly increase since September 2014.
Coffee and tea
While not a significant proportion of household
expenditure, the price of Coffee, Tea and Cocoa rose 8.2% in the last year in
contrast to the long-term trend of only 0.8% per year.
The impact of cost of living increases on
individual consumers will depend on their individual spending habits, for
example takeaway
coffee rising from $4 to $7.

Weighting and averaging of household expenditure
Households do not spend equal amounts on each
expenditure class, so the CPI applies weightings to price rises according to
the proportion of total household expenditure each class represents.
For example, Transport costs rose 13.7% but
represent 10.6% of average household expenditure, so accounted for a 1.6% rise
in total household costs.
In contrast Coffee, Tea and Cocoa rose 8.2%, but
as it only represents 0.2% of household expenditure, accounted for only a 0.4%
rise in total costs.
The CPI can only measure average household
expenditure across all households and cannot account for varying expenditure on
different expenditure classes. For example, if the price of new motor vehicles
increases, there is no impact on a household that did not purchase a new
vehicle in the period; however, the CPI can only measure the impact as if the
price increase for new vehicles were averaged across all households.

Selected Cost of Living Cost Indexes
The ABS Selected Living Costs Indexes (SLCI) are
useful in understanding levels of inflation within selected household types
defined by their main source of income.
| Household type / SLCI |
Principal source of income |
| Employee households |
Wages and salaries; |
| Age pensioner households |
Age pension or veterans’ affairs pension |
| Other government transfer recipient households |
A government pension or benefit other than the age
pension or veterans’ affairs pension |
| Self-funded retiree households |
Superannuation or property income |
| Pensioner and Beneficiary Living Cost Index |
Age pension or veterans’ affairs and other pension
government pension or benefit combined |
Australian Government payments such as the Age
Pension, Service Pension and the Disability Support Pension are regularly
indexed by the greater of the movement in the CPI or the movement in the
Pensioner and Beneficiary Living Cost Index (PBLCI).
SLCIs include interest charges but do not include
new house purchases, while the CPI includes cost of new house purchases but
does not include interest charges.
The most notable variations in household spending
patterns are:
- Age Pension households spend a greater proportion on ‘Health’
compared to the average Australian household (12.2% versus 6.5%), but less on
‘Education’ (0.2% versus 4.6%).
- Employee households spend a greater proportion on Insurance and
Financial Services (9.5% versus 5.8%) as this includes home mortgage and
credit interest payments.
- Employee households spend a lesser proportion on Housing (15.1%
versus 23.2%).

Comparing the movement in Cost of Living Indexes
and the CPI
Over the long-term, the trends are similar with
SCLIs rising at a slightly higher annual rate than CPI for Other government
transfer recipient households (2.8%), and Self-funded retiree households
(2.9%) but slightly lower for Employee households (2.4%) and Age pensioner
households (2.5%)
- In the most recent year all SLCIs rose at a rate less than that of
CPI, with the lowest increase being for Age pensioner households at 3.8% and
highest for Other government transfer recipient households at 4.9%.
These differences principally reflect the treatment
of housing and interest costs between the 2 types of indexes.

Price rises compared to income
To properly assess the impact on cost of living,
price increases need to be assessed in the context of household income. If
household income does not increase in line with inflation, then wages are said
to be decreasing in real terms. The ABS also produces the Wage Price Index
(WPI) which measures changes in the price of labour.
While over the previous 20 years the WPI has
generally kept pace with CPI, since the June 2021 quarter, CPI increases have
out-weighed WPI increases.
In the March 2022 quarter, the WPI annual increase
for Australia was 2.4% compared with the CPI of 5.1%.
