In 2016, two years after new alcohol control legislation (i.e. the lockout laws) went into effect in New South Wales, 70% of voters supported the legislation – by 2018 this declined to 48%. This project will analyse Twitter data regarding these laws (2014-2018) to understand how online publics construct social media narratives around controversial public health issues and public posturing towards related regulatory policy (i.e. liking and willingness to comply). This will inform tailored strategies for policy stakeholders seeking to build legitimacy and trust in public health regulation.
