Footage of endangered sharks entangled in nets along Sydney's Palm Beach has renewed calls for the state government to end its controversial mesh net program.

Scalloped hammerhead sharks, which are listed as endangered by the NSW Department of Primary and Industries, were photographed caught and wrapped up in the nets this year.

The video and photos were released by conservation groups Humane Society International and the Australian Marine Conservation Society at the end of the 2018/2019 NSW shark netting season on Tuesday.

AMCS shark campaigner Leonardo Guida claims the nets are ineffective at keeping swimmers safe and instead drown iconic and harmless animals, such as turtles, dolphins and hammerheads.
