The development of open government data (OGD) has spread all around the world. The vast datasets that were proactively published on the OGD portal would be beneficial for government and its citizens. There are some factors that might enable OGD usage to create public values for the users and communities in the public sector. The OGD literature shows that there is a huge gap of an empirical research. This research aims to identify the salient factors that enable or inhibit a successful OGD usage and its beneficial outcomes in Australian public sector. This research has drawn on the Moore’s framework (1995) for creating public values and the information systems success model framework as theoretical backgrounds to conduct survey research from a government employee perspective to address the gap in the literature.
