The non-modal wave angle caused a partial rotation of the sediment Southwards but lacked a full rotation due to the formation of a rip current from the Long Reef head which transported the sediment offshore. There are anticipated changes over a longer time scale where projections indicate an anti-clockwise rotation in the mean wave direction for the South-West Pacific region (ibid) in the direction and increasing height of waves; this is a signature of climate change (Mortlock et al.
