Shoalhaven Riverwatch's massive clean up operation

Rusted, smelly shopping trolleys and poisonous plastics were high on the list of rubbish pulled from the Shoalhaven River during a clean-up operation.

Shopping trolleys, plastic bags and drink bottles, tyres, a shaft from the back wheel of a truck, fishing lines and rods and several push bikes were among the items dragged from the river on Tuesday.

Volunteers from Shoalhaven Riverwatch took part in the massive clean-up operation.

Their haul adds to the mountain of rubbish collected around the region on Sunday during Clean Up Australia Day.

Margie Jirgens from Riverwatch said they hope people are getting the message about cleaning up after themselves but added that more work was needed.

Meanwhile, during a week of action over 587,962 volunteers have joined together to protect their local environment and clean up the parks, waterways, beaches, bushland and roadways that are important to them at more than 7,253 locations across Australia for Clean up Australia Day.

 This is a 14 per cent increase in site and four per cent increase in volunteer numbers over 2017.

Since the event started 28 years ago Australians have donated more than 33 million volunteer hours, removing the equivalent of 350 thousand ute loads of rubbish from over 178 thousand sites across the country.
