The article highlights a dramatic decrease in the price and revenue of macadamia nuts, with the price dropping by 62% from US$2.91 to US$1.09 per kilogram, and revenue falling by 39% from US$13.72 million to US$8.35 million between 2020 and the current season. This decline is primarily attributed to an oversupply in the European and American markets, resulting in prices reaching their lowest in the past 20 years.
