By his own admission, Australian Prime Minister Gough Whitlam was not much of an economist, a disclosure that has fuelled criticisms of his government's performance during the economic crises of the 1970s. By contrast, Whitlam was a self‐declared internationalist who promoted the domestic and global possibilities of the international system. Of course, twentieth‐century economics and internationalism were mutual rather than dichotomous. Accordingly, Whitlam's internationalism provides a vantage point to re‐evaluate his economics. This article focusses on how one strand of Whitlam's internationalism — his Third World sympathies and alignments — informed his government's resource policy, as designed by Minister for Minerals and Energy, Rex Connor. Rather than seeking to redeem Whitlam's economic credentials via this internationalism, however, I argue Whitlam's appeal to Third Worldism sought to infuse an anti‐economics — or, more precisely, a critique of mainstream economic thinking — into Australian resources policy. The legacies of this critique have been enduring. Whitlam and Connor's attempts to establish export controls, foreign investment regulations, and state‐owned enterprise galvanised a fierce backlash from miners and libertarian economists. This backlash has helped shape the neoliberal framing of Australian mining and energy policy over the past 40 years. At the same time, with climate change and energy transitions again illuminating the politics of natural resources, Whitlam's Third World critique remains salient.
