The audit reviewed the Defence's $5.05 billion New Submarine Project which commenced in 1982 and involves design and construction of six Collins class submarines and associated supplies and services. The objectives of the audit were to assess project management by the Department's Project Office in the light of accepted better-practice project management techniques. It also aimed to derive lessons learnt and recommendations that could be applied to the Project and to similar Defence projects now and in the future. The audit follows a 1992 audit of the Project by the ANAO and a review by the Joint Committee of Public Accounts in 1995.
