Per the Australian Bureau of Statistics, the Wage Price Index (WPI),

measures changes in the price of labour, unaffected by compositional shifts in the labour force, hours worked or employee characteristics.

The WPI is a key measure of the Australian labour market. It is "the major measure of inflationary pressure on wages and salaries." The seasonally-adjusted quarter-to-quarter percentage change in WPI also serves as a critical point of discussion in forecasts of the post-COVID Australian economic recovery.

Thanks to the Australian Government's Public Sector Workplace Relations Policy, the relationship between public and private sector WPI is also legally important: for a large portion of government employees, annual adjustments to remuneration are capped in line with the private sector WPI change.

The ABS has reported the WPI statistic quarterly since 1997. A full table of quarterly WPI data is available for download.

What will be the percentage change of Australia's seasonally-adjusted Private Sector WPI for Q3 2021?
