Australian National Accounts: Input-Output Tables

The Input-Output (I-O) tables are part of the Australian National Accounts. They complement the quarterly and annual series of national income, expenditure and production aggregates. They provide detailed information about the supply and use of products in the Australian economy, as well as the relationships between Australian industries and their structures. The data published in this release is consistent with the latest release of the Australian System of National Accounts.

This publication contains the I-O tables and I-O Product details tables for 2023-24. The I-O tables include:

• basic transactions
• coefficients
• industry flow
• margins

The Product details tables cover more than 900 products. The details include:

• Australian production
• imports and exports
• margins
• taxes and subsidies
• intermediate and final usage

Previous I-O tables were produced for 1958-59, 1962-63, 1968-69, 1974-75, 1977-78 to 1983-84, 1986-87, 1989-90, 1992-93 to 1994-95, 1996-97, 1998-99, 2001-02, 2004-05 to 2009-10, and 2012-13 to 2022-23.

The 2023-24 I-O tables and the I-O Product details tables are available in the Data downloads section.

This release includes one update to the I-O product classifications (IOPC) in the I-O Product details tables.

This change is based on the implementation of historical revisions regarding the incorporation of solar generated electricity into the Supply-Use tables. Refer to the Impacts from the 2025 Annual National Accounts historical revisions article for further details of historical revisions improvements, and to the Household solar electricity generation in the Australian national accounts article for further information about household solar electricity generation.

New IOPC added to IOPG 2601:

• 26190020 Household electricity production for own use

This change is reflected in the Industry and product concordances section on the Input-Output tables methodology page.

This data presents information on supply and use by industry and product. It shows Australian production, imports, intermediate usage, final usage, exports, margins and taxes less subsidies on products.

Columns in the Input-Output (I-O) tables and I-O Product details tables both show the industry classification Input-Output Industry Group (IOIG). Rows in the I-O tables show the product classification Input-Output Product Group (IOPG). Rows in the I-O Product details tables show the product classification Input-Output Product Classification (IOPC).

IOIGs are based on the Australian and New Zealand Standard Industrial Classification (ANZSIC). IOPGs are groups of IOPCs aggregated to the IOIGs to which they are primary. 

The IOPC is an industry-of-origin product classification that has been specifically developed for the Australian I-O tables. The I-O system describes the production and subsequent use of all goods and services. Each I-O product classification is defined by characteristic products of industry sectors. The overall principles for such an industry-of-origin product classification include:

• Homogeneity of inputs - each product or product group should consist of items that have similar input structures or technology of production. This principle is generally applied through the definition of each IOPC item in terms of the ANZSIC industry in which it is primarily produced.
• Homogeneity of disposition - each product or product group, having satisfied the first criterion, should consist of items that have similar patterns of disposition or usage. This principle is applied by reference to the description of source data items and information about the transport, distribution and product taxation margins applying to particular products.

This structure in the IOPC uses ANZSIC classes as the basis for defining IOPC items. IOPC items are identified by an eight-digit code. The first four digits typically refer to the ANZSIC class to which the item is primary. The last four digits are the product number. The Industry and product concordances section on the Input-Output tables methodology page details the relationship between ANZSIC codes, I-O industry groups and other industry and product classifications.

The IOPC used in this publication is consistent with the 2006 edition of the Australian and New Zealand Standard Industrial Classification (ANZSIC). The IOPC has over 900 individual product items.

The alternative view of the Input-Output tables is produced for use in large and sophisticated models.

The variation relates to the treatment of imports data and offsets the treatment of freight and insurance services provided on imports by residents. These are already part of domestic output and should not be treated as imports. In the main tables, therefore, imports of freight and insurance services are adjusted downwards at an aggregated level.

This adjustment, while conceptually correct, can generate negative values for imports of transport services for some industry groups. However, this adjustment is an accounting entry only, with no economic meaning. 

In the alternative view, the value of freight and insurance on imports has been added back into imports. This removes negative values. To maintain the balance on the current account, a similar value has been added to exports. The value of this adjustment in 2023-24 is $2,173m.

The alternative view is available in the Data downloads section.
