The Port Lincoln Dive Shop will drive an underwater clean up effort this weekend to remove exposed debris around the town jetty.
There have been two dives like this before but this is the first one for a couple of years.
“What we're looking at is debris - jetsam - which is human waste material,” Leo Stewart from The Dive Shop said.
Mr Stewart said when storms and strong winds blew through it could expose all kinds of debris.
The debris includes glass bottles, car tyres, jetty debris and other old material that has built up over many years.
“There's plenty of people that have created interest in joining in,” Mr Stewart said.
“I could do with a few more people topside as we can only have a limited amount of divers.”
The clean up is this Saturday, March 25 at 10am. Divers are asked to be at the dive shop at 8.30am to get their gear ready before hitting the water.
