The Ai Group Australian Industry Index® eased in October 2023, dropping 6.5 points to -9.9 points (seasonally adjusted). The index, which reports industry conditions and sentiment, has indicated contraction for the last 18 months.

Key findings for October 2023:

  • The Ai Group Australian Industry Index® shows a broader range of industrial businesses reported contractionary conditions in October.
  • The employment, activity and new orders indicators all fell.
  • The Australian PCI® construction indicator continued a rally, rising strongly into expansion to post its highest score since March 2021.
  • Machinery & equipment continued a recovery trend, while business services and upstream manufacturers still report slow conditions.
  • Price indicators all remained strongly positive, but the sales price indicator eased. The wages indicator was stable but high, and continues to point to strong wages pressure.

Innes Willox, Chief Executive of the national employer association Ai Group said: "The employment index fell back into contraction in October, while activity and new orders declined more steeply than in the previous month. Further improvement in the Australian PCI® indicator is a positive sign, with a broader range of construction firms reporting improved trading conditions. But the Aii indicates a worsening of contractionary conditions in the industrial sector as a whole. This is particularly evident in upstream manufacturing sectors and business services," Mr Willox said.

About the Ai Group Australian Industry Index®
The Ai Group Australian Industry Index® is a monthly index that measures changes in activity in Australia’s industrial sectors. It provides diffusion indices which measure rates of changes in the level of industrial activity – expansion, stability, or contraction. A positive reading indicates the activity is expanding; negative indicates contraction. The distance from 0 indicates the strength of the expansion or decline.


The Australian Industry Index is based on monthly surveys from a national sample of Australian businesses. It uses ANZSIC industry codes for classifying sectors, and weights survey results using ABS data on gross value added by sector. Seasonal adjustment and trend calculations follow ABS methodology.
