Effective Human Resource Development (HRD) has long been recognised as a critical element in overall organisational strategy, and in turn is important to the ongoing sustainability of organisations. In this paper, the importance of effective HRD strategies and interventions are considered, particularly in the context of a rapidly changing environment, requiring those within the organisation to change past behaviours and accumulate new knowledge at an ever-growing rate; more recently referred to a unlearning. Based on research undertaken in organisations located in regional Queensland and the Northern Territory, Australia, it is argued that effective HRD strategies are just as important in these locations as anywhere else. The level of consideration given to unlearning as a component of broader HRD initiatives, along with the systems utilised to reinforce learning in these organisations is analysed. The results of the survey provide some initial perceptions of the importance of unlearning, as well as an indication of the mechanisms being utilised to reinforce unlearning and ensure that new learning is embedded.
