The Sand Pumping Jetty at Main Beach is a 494-metre working engineering structure that extends out to sea near the Gold Coast Seaway.

It forms part of the Gold Coast Sand Bypass System, which intercepts the natural northward drift of sand to help maintain navigable access through the Seaway.

Sand collected at the jetty is pumped through an underground pipeline and redistributed along the coast, delivering up to 500,000 cubic metres of sand annually to beaches including Main Beach, Surfers Paradise, and The Spit.

A pipeline upgrade extended the system to 6. 4 kilometres of DN450 polyethylene piping, with booster pumps and temporary beach outlets enabling efficient sand redistribution along this stretch of the Gold Coast's northern beaches.
