Purpose - This paper presents an empirical investigation of the critical determinants for the adoption of emarket in Australian small-and-medium sized enterprises (SMEs) within the technology-organizationenvironment (TOE) framework. Design/methodology/approach - A conceptual model is proposed for better understanding the adoption of emarket in Australian SMEs. Structural equation modelling is used for testing and validating the proposed conceptual model based on the survey data collected from Australian SMEs. A logistic regression analysis is conducted for identifying the relationship between the critical determinants and the adoption of e-market in Australian SMEs. Findings - A positive relationship is identified between the perceived direct benefit, top management support, external pressure, trust and the adoption of e-market in Australian SMEs. The top management support emerges as the most critical determinant. The perceived indirect benefit, size and organization readiness, however, do not show a significant influence on the adoption of e-market in Australian SMEs.
