Increasingly, volunteer managers are facing a typical marketing problem: how to identify the right consumers (in this case volunteers); attract them; and keep them loyal. In multicultural societies this challenge is amplified because of the many different groups originating from countries that can vary significantly in terms of the extent and nature of volunteering and the reasons for being involved. Often, the consequence of this heterogeneity is limited success of generic, community-wide marketing and recruitment campaigns.Using the Theory of Planned Behavior, we investigate whether significant differences exist between Australian residents from different cultural backgrounds in their volunteering behavior. Groups were found to differ in attitude, social norm and perceived behavioral control, suggesting the need for customized rather than market-wide marketing strategies.Results are theoretically important because they provide empirical evidence that volunteers in multicultural societies cannot be viewed as one homogeneous mass. Practically, the results provide detailed insight into each cultural group and the factors which influence their behavior. This can be used to create customized campaigns to tap into the large, but underutilized, base of volunteers from different backgrounds.3
