Abstract: Fly-in fly-out (FIFO) workforces have become a major part of Western Australia’s mining industry. The Regional Development Council (the Council) is of the view that the increasing use of FIFO on resource projects in regional WA represents a loss of real and potential benefits to regional communities. The Council is concerned that the economic and social impacts of FIFO (relative to the use of a permanently based regional workforce) are not currently incorporated into the analysis underpinning the current project decision making process. Failure to fully understand the regional impacts of a proposed project prevents the Government, community and project proponents from developing and implementing strategies that would result in better regional outcomes and allow for forward planning to address possible bottlenecks and shortcomings. ACIL Tasman has undertaken an analysis of available economic models and modelling/analytical techniques, with particular reference to their suitability for potential use in the Western Australian State Government Approvals process. The purpose of this study is to recommend a suitable approach to modelling/analysing regional resource projects to ensure that the economic impacts of a FIFO versus a residential workforce are understood.
