WESTAC membership is unique in that the membership sits with the member organization, not an individual. Member organizations span the modes and sectors of surface and water transportation: carriers and logistics providers, ports and terminals, shippers, labour unions and the three levels of government. The active participants are industry executives, labour leaders, elected politicians, and senior government officials.
WESTAC has a small number of Sustaining Member organizations. These members provide stability and enduring commitment to WESTAC and its values and goals.
