The town of Moulamein on the Edward River and Billabong Creek in New South Wales has a population of about 500. It is protected from flooding by two (2) levee systems surrounding the town. Total levee length is approximately 7.5 kilometres consisting of a ring shaped levee surrounding Moulamein North and another levee surrounding Moulamein South. The levee was originally constructed prior to the 1956 flood but some additional work was initiated with the approach of the flood of 1956.Works to raise the levee by 0.6 metres were carried out in 1984 to achieve a design level equal to the 1956 flood plus 0.8 metres.

The audit is designed to appraise the flood security and structural adequacy of the levee system at Moulamein. This report presents the results of that audit and consists of a visual appraisal of the levee and materials, assessment of the water retention capacity of the levee, research of flood records and an appraisal of the cost of corrective action and the extent of such action.
