The Australia Institute

The Australia Institute is an Australian public policy think tank based in Canberra. Since its launch in 1994, it has carried out research on a broad range of economic, social, and environmental issues. The Australia Institute states that it takes a bipartisan approach to research, but it has been described as "progressive" or "left-leaning".

The Australia Institute has faced criticism over alleged links with the Australian Greens, with critics arguing these connections undermine its claim of being non-partisan. Media reporting has highlighted that several current and former senior figures at the Institute have held roles with the Greens, including founder and former executive director Clive Hamilton, who ran as a Greens candidate in 2009, former executive director Ben Oquist and current executive director Richard Denniss, both of whom previously worked in the office of former Greens leader Bob Brown, and other staff who have served as advisers or communications officials for the party. Former deputy chair Barbara Pocock resigned from the Institute before entering the Australian Senate as a Greens senator in 2022. Critics, including some within the Australian Labor Party, have pointed to policy alignment between the Institute and the Greens on issues such as tax, climate, energy and defence as further evidence of political affinity. The Australia Institute has rejected these claims, stating it has no formal political affiliations and arguing that its independence is demonstrated by its willingness to criticise or support policies from any political party based on its research.
