Duranbah Beach has high recreational and economic value even though it is small, as it has a well known, consistent surf break. The northern end of the beach is eroding due to longshore drift. To address this, the beach is nourished twice a year with sand sourced as part of the Tweed Sand Bypass project, which takes accumulated sand from the mouth of the Tweed River and deposits it in various beaches to the north (see Tweed Sand Bypass project page). Additionally, the surf break is in large part determined by the sand conditions of the Tweed River delta, and thus the maintenance of the sand delta through the bypass system also maintains the surf break.
