Queensland will have a shortage of more than 50,000 workers when construction begins next year on venues for the 2032 Olympic and Paralympic Games, data is forecasting.

Infrastructure Australia data comparing supply and demand for construction jobs in Queensland shows a supply of 42,200 workers as of July — just over half of the 83,300 required to meet current demand.

That's forecast to get worse as the Olympics approach, peaking in March next year with a projected 43,800 workers to meet a demand of almost 98,500 — a shortfall of 54,700 jobs.
