The Australian Macadamia Society forecasts a 16% increase in the country's macadamia shell production for the 2024 season, reaching 56,000 tons with a moisture content of 3.5% or 60,000 tons with a moisture content of 10%. This growth is expected despite recent rainfall and rising input costs, attributed to favourable growing conditions and a positive outlook among growers. The official forecast is based on a scientific model from the Queensland Department of Agriculture and Fisheries, and a review of historical crop yields after periods of low prices.
