An online survey of workload activities was circulated to academics across Australia seeking estimates for the time to undertake a range of academic-related tasks associated with teaching, research and service. This article summarises the most important findings from the teaching data of the 2059 respondents. This detail of workload data has not been reported before across the Australian university sector. The findings showing that most academics work more than 50 h per week are consistent with previous studies. Although the estimates of the individuals varied greatly, statistical inquiry indicated the median time required does not vary by experience and online teaching generally requires more preparation time than on-campus teaching. The paper proposes this methodology as a credible means to derive realistic time-based standards for other aspects of academic work and will assist university managers by providing an external benchmark upon which to develop local academic workload models.
