There has been a plethora of research on the internet and web sites especially in the area of usability. In addition, much of the research has focused on small to medium sized businesses. Little attention has been given to the purpose and content of web sites especially large organisations in an Australian setting. This study proposes a four stage model of e-commerce activity using the level of interaction as a measure to classify the web sites of 133 large Australian companies. The findings from the research suggest that many large Australian companies, whilst having a web presence, are not exploiting the available technology to conduct even a low level of e-business. Most companies are still at the early stage of e-commerce.
