Health prices

It is useful to understand how changes in health spending are related to price movements (for example, inflation) rather than the volume or nature of services being purchased and how this compares with the general economy. Between 2022–23 and 2023–24, health prices grew by 4.93%. General inflation, measured using the implicit price deflator (IPD) for gross national expenditure (GNE), was 4.6%. As such, ‘excess health inflation’ was 0.31%, indicating that prices of health goods and services rose slightly faster than prices in the broader economy (Figure 5).

Over the decade to 2023–24, prices in the health sector grew at an average annual rate of 2.56%, compared with prices in the broader economy with an average yearly growth rate of 2.51%. This resulted in varying levels of excess health inflation over time, ranging from –2.16% in 2022–23 to 1.41% in 2016–17.

The line graph shows annual health inflation rates and general inflation rates from 2013–14 to 2023–24. Between 2014–15 and 2020–21, both rates fluctuated. Annual health inflation ranged between 1.66 and 2.25%. General inflation, based on the GNE IPD, varied between 0.83% and 2.09% during the same period. Health inflation increased significantly between 2020–21 and 2023–24, rising from 2.01% in 2020–21 to 4.93% in 2023–24. General inflation rose sharply from 1.12% in 2020–21 to a peak of 6.50% in 2022–23, before declining to 4.61% in 2023–24.

Inflation and deflators

Inflation refers to changes in prices over time. It can be positive (prices are rising over time and the same volume of goods cost more, so money is losing value) or negative (the same volume of goods is costing less).

Inflation in the broader economy is measured using price indexes, also known as deflators. These show the amount a price has changed over time relative to a base year. The reference year, or base year, for the deflators used in this report is 2023–24.

Health inflation

Health inflation is a measure of the average rate of change in prices within the health goods and services sector of the economy.

See Concepts and definitions: Deflators for more information on health deflators and industry-wide deflators.

General inflation

General inflation refers to the average rate of change in prices throughout the economy over time. There are different ways to measure the economy, and many methods for deriving deflators. The specific deflator can affect whether prices in the health sector appear to have risen slower or faster than the general inflation rate (excess health inflation).

In this report, the measure used for this is the IPD for GNE. GNE is a measure of the value of final expenditures on the goods and services purchased in the economy by all parties including governments and including imports but excluding exports. IPD is an indicator of changes in the purchase price of these goods.

Excess health inflation

Excess health inflation is the amount by which the rate of health inflation exceeds general inflation. Excess health inflation will be positive when health prices are rising more rapidly than prices generally throughout the economy. It will be negative when the general level of prices throughout the broader economy are rising more rapidly than health prices.

Health spending and gross domestic product

The ratio of health spending to GDP, showing the proportion of total economic activity represented by the health sector, is an indicator of the contribution of health spending to the overall economy.

In 2023–24, health spending accounted for 10.1% of GDP in Australia, approximately 0.2 percentage points higher than in 2022–23 (Figure 6). The ratio of total health spending to GDP increased gradually during the first half of the decade (2012–13 to 2015–16), then flattened out. It increased and reached 10.7% in 2020–21 before declining to 10.5% in 2021–22 and further to 9.9% in 2022–23. However, the ratio increased to 10.1% in 2023–24. This suggested that health system entered the post-pandemic period. 

See International comparison of health spending for comparing the ratios of the health spending to GDP among OECD countries.

The line graph shows that annual growth rates in Gross Domestic Product (GDP) were more volatile than the annual growth rates in total health spending from 2013–14 to 2023–24. Annual growth in total health spending ranged from 3.1% to 9.5%, while GDP growth rates varied more widely, from 1.6% to 11.7%. Over this 10-year period, the ratio of health spending to GDP remained relatively consistent and increased overall from 9.6% in 2013–14 to 10.1% in 2023–24.
