Jimmy's Beach is eroded each year primarily from storm events, particularly the east coast low pressure systems that cause strong swell each winter. The current management plan involves renourishing erosion hotspots along the beach as needed after storm events, as well as overall nourishment each autumn to construct a sacrificial buffer of sand before the storm season. Sand dredged from the nearby Lower Myall River is stockpiled at Winda Woppa to the south of the beach, and then used from there as needed. In 2019, a permanent sand pumping system was installed to enable easier movement from the stockpile at Winda Woppa. This stockpiling and as-needed renourishment method is successful in terms of minimising effort and costs, with yearly maintenance costing around $200,000/year. The $4.1 million project was funded by NSW Office of Environment and Heritage, MidCoast Council and the Department of Primary Industries Crown Lands and Water.
