Coastal Warriors - Mid North Coast volunteers are overwhelmed with plastic waste at each clean-up.
The group's vice-president, Addam Lockley, said plastic made up the majority of the litter collected.
Mr Lockley said that showed just how much society relied on plastic.
Plastic food packaging, such as chip packets and lolly wrappers, and cigarette butts, which contain plastic, are among the litter culprits.
The clean-ups also yield items from paper-based rubbish to aluminium and glass.
Coastal Warriors - Mid North Coast is committed to preventing plastics and other harmful products entering waterways by cleaning beaches, parks and gardens.
Mr Lockley believes Plastic Free July is a great initiative.
"Anything that creates awareness is beneficial to the community," he said.
"We really want to reduce what's ending up in the environment.
"The more awareness is raised, it creates talking points for people, which can lead to education to go for better choices."
Plastic Free July is a global movement to reduce plastic pollution.
The campaign encourages people to be part of the solution in their homes and the community.
A good starting point is swapping single-use coffee cups for reusable cups, and embracing reusable shopping bags and reusable water bottles.
"It becomes a habit to remember to take your cup and your bag," Mr Lockley said.
He said the majority of the community was on board with making better choices for the environment.
Coastal Warriors - Mid North Coast's next clean-up is at Lighthouse Beach from 8am to 11am on August 10.
Meanwhile, Lake Cathie's eco warrior Shalise Leesfield also supports Plastic Free July.
