In Australia, there is an emerging tendency among SMEs towards the adoption of cloud computing.
However, there are limited studies investigating the factors that influence cloud computing adoption
within Australian SMEs. To fill the research vacuum, we developed a research model based on the
diffusion of innovation theory (DOI), the technology-organisation-environment (TOE) framework, and
our prior exploratory study to investigate the determinants that influence the adoption of cloud
computing. An organizational-level survey was conducted across Australia to collect data from
technology decision makers in SMEs. Data collected from 203 firms are used to test the related
hypotheses. This study contributes a statistically validated model of the influential determinants of
cloud computing adoption. Data analysis indicates that Technological Factors (cost savings, relative
advantages, compatibility, and trialability), Organizational Factors (firm size, top management
support, innovativeness of the firm, and IS knowledge), and Environmental Factors (market scope and
external computing support) were found to be determinants of the adoption of cloud computing
services. Benefits of the findings are twofold. First, they provide knowledge about cloud computing
determinants in the Australian marketplace. Second, they provide policy planners and SMEs’ decision
makers with insights and directions for successful adoption of cloud computing technology.
