Wave buoys explained
Department of Science, Information Technology, Innovation and the Arts has waverider buoys along the coast to measure the heights of waves at sea. The Manly Hydraulics Laboratory in Sydney runs a similar program along the NSW coast.
The data from these buoys provides useful information for coastal management and planning.
The boating and fishing public also benefit from the data as an indication of sea conditions offshore and as a guide to swell size and direction on coastal bars.
The buoys often have schools of Mahi Mahi around them. Catch a few, but leave some for others. Make sure you keep trolling lines clear and never tie up to, or interfere with, the buoy.
