There are several applications and benefits of Blockchain Technology (BCT) reported for different industries e.g. health, finance, supply chain, government, and energy. However, despite the benefits reported in the scholarly and commercial literature, organizations have not adopted BCT heavily across the globe including Australia. This lack of uptake provides the rationale to initiate this research to identify the factors that influence the adoption of BCT among Australian organizations. We use a mixedmethods approach based on the Technology, Organization, Environment (TOE) framework. First, we develop a theoretical model grounded on the findings of qualitative interviews of BCT experts and decision-makers working with different Australian organizations, and then confirm it through a quantitative study with an online survey. The results of the study show that the organizational adoption of BCT is influenced by the different factors that belong to the technological, organizational, and environmental contexts of the TOE framework.
