Developing economies across the world face high public corruption and weak financial management, and the role of sound audit practices in shaping the narratives is still at the exploring stage in most countries in sub-Saharan Africa. This research explores the nexus between public audit reforms and public sector financial management using survey research design and Nigeria as a case study. Participants in the study were drawn from The Office of the Auditor General of the Federation (OAuGF) Headquarter in Abuja. Agency theory anchored this study and simple descriptive analytics was used in testing the seven hypotheses. The research established that: the recent audit reforms carried out in Nigeria are considered necessary for better public sector financial management; Nigeria’s audit system has a strong connection with public sector financial management; there is a need for the establishment of Federal Audit Service Commission (FASC) in Nigeria; the recent audit reforms will block treasury loot and leakages in Nigerian public funds management; Nigeria needs effective audit laws to wholesomely fight corruption through recent audit reforms; and the recent Nigerian audit reforms embrace integrity, transparency and accountability in the management of public funds. The study makes the following recommendations: there is a need for audit staff orientation and professional development in order to promote their overall productivity and efficiency; there is a need for the establishment of Federal Audit Service Commission (FASC) in order to promote the independence of Nigerian Audit system from executive interferences; Nigeria audit laws should be strengthened to curtail fund leakages, wastages of public property, and promotion of value-for-money expenditures; and the recent audit reforms carried out by the government of Nigeria should be sustained and given all necessary supports in order to achieve the desired results.
