Using taxation statistics, we estimate the income share held by top income groups in Australia over the period 1921-2002. We find that the income share of the richest fell from the 1920s until the mid-1940s, rose briefly in the post-war decade, and then declined until the early-1980s. During the 1980s and 1990s, top income shares rose rapidly. At the start of the twenty-first century, the income share of the richest was higher than it had been at any point in the previous fifty years. Among top income groups, recent decades have also seen a rise in the share of top income accruing to the super-rich. Trends in top income shares are similar to those observed among other elite groups, such as judges, politicians, top bureaucrats and CEOs. We speculate that changes in top income shares may have been affected by top marginal tax rates, skill-biased technological change, social norms about inequality, and the internationalisation of the market for English-speaking CEOs.
