The town of Oxley is located 90km north east of Balranald on the Lachlan River in New South Wales, has a population of about 15 and is protected from flooding by a 2.2km levee surrounding the town.

The levee was constructed in 1989 to the 1956 flood level plus O. 5m free board under controlled conditions. Construction and raising occurred under the supervision of the Baranald Shire Engineer and a high standard of construction was reported to be achieved.

To date the town of Oxley has not been inundated as a result of failure of the levee.

The audit is designed to appraise the flood security and structural adequacy of the levee system at Oxley. 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.
