A key limitation at a number of locations in Australia is the availability of suit-
able sediment for beach renourishment. As a result a number of studies have been
carried out to establish the need for availability of offshore sources around Sydney
(AECOM
2010
) in relation to the estimated future sediment requirement for beach
renourishment to protect Sydney beaches from continued erosion and future sea
level rise. A significant limitation is that offshore resources of sand in New South
Wales are currently protected by legislation, restricting the extraction of sand
resources from the seabed.
In New Zealand a number of examples of beach renourishment projects exist,
