- More thorough surveying of shore protection structures to determine crest levels, the ground elevation at the toe of the structures and general condition. Elevations based on LiDAR were used, and this is a significant uncertainty.
- Continue maintenance of shore protection structures, and investigate ways to improve the standard of protection of these in future.
- Formalise the protection structures on the eastern river bank at Ocean Grove for flood protection purposes in future.
- Sea-level at Portland should be examined in order to predict any possible storm-tide events when high flows are expected within the Barwon River.
- An assessment of the resilience of the estuary saline habitats to increases in sea-level, and identify appropriate areas of land (based on elevation and potential future frequency of inundation) as compensatory habitat areas for the areas that may be lost due to sea-level rise.
