There is debate over the extent reached by unemployment in Australia, often cited as peaking at 29% in 1932. "Trade Union figures are the most often quoted, but the people who were there…regard the figures as wildly understating the extent of unemployment" wrote historian Wendy Lowenstein in her collection of oral histories of the Depression. However, David Potts argues that "over the last thirty years …historians of the period have either uncritically accepted that figure (29% in the peak year 1932) including rounding it up to 'a third,' or they have passionately argued that a third is far too low." Potts suggests a peak national figure of 25% unemployed.
