Australia’s website blocking regime, introduced in 2015 and expanded in 2018, is a work-in-progress. The regime provides an avenue for rights-holders to seek injunctions requiring Internet service and search engine providers to block access to overseas websites that have the ‘primary effect’ or ‘primary purpose’ of infringing or facilitating the infringement of copyright. Furthermore, rights-holders and service providers may by agreement extend the injunction to new web addresses that provide access to the same online location without returning to court (thereby addressing the whack-a-mole problem of mirror sites). This article critically analyses the trajectory of this so-called ‘no fault’ enforcement regime and the potential problems that could arise if we continue on this path. It challenges the conception of the regime as a form of proprietary protection and, as a result, the uncritical reliance on private ordering as a keystone of online copyright enforcement. It highlights the lack of transparency fostered by the current regime and recommends measures for addressing these flaws in the design of Australia’s copyright site blocking regime.
