The purpose of this research is to examine online purchase behaviours amongst young consumers in Australia and the United States of America. It also aims to develop and test a theoretical framework of young consumer's online purchase behaviour. Data were collected through online surveys targeting young online shoppers in Australia and the United States. A multi-group Structural Equation Modelling (SEM) was employed to test the proposed structural model and hypotheses.

• The model shows a good fit with the data.
• Young consumers in Australia and the United States have positive attitude towards online shopping that significantly affects their online purchase intentions.
• Social motive negatively impacts online purchase intentions in the Australian sample.
• Escapism and value motives positively affect Australian and American young shopper's online purchase intentions.
• Young consumers in Australia and the United States are very familiar with the online shopping process. The familiarity strongly triggers their information search behaviour that leads to the online purchase intentions. Results of this research assist the marketers and policy makers to target and appeal to this young segment, based on their unique motivations, values, and characteristics. Utilising the Generational Cohort Theory, this research contributes to the extant literature by providing insights on the Australian and American young generation's unique values and characteristics that influence their online purchase behaviours. This research also contributes insights for the marketers and policy makers to improve their marketing efforts and services and appeal to this young segment, based on their unique values and characteristics.
