A BEACH walker, who didn't want to be identified, was shocked to find two syringes lying on a beach near Kingscliff on the weekend.

The woman walks regularly on the beaches north of Kingscliff but she never thought this sort of thing was a concern.

"(When I first saw it) my first response was shock and then horror because one of the kids picked it up," she said.

"I would assume (it was illegal drug users) because we found another one shortly after. I would assume that's what they were used for.

"I was pretty angry and disgusted. Angry that they're so unthinking of other people and the people who might stand on it."

Cudgen Headland Surf Life Saving Club captain Gary Cain said members had never found syringes on the beach in Kingscliff.

The woman who discovered the syringes said she understood that policing drug use on the Tweed's beaches was difficult.

"I don't know that the police can do anything about it. They're stretched as it is. People need to clean up after themselves," she said.

"I think it indicates there are regular users down there and there need to be enough proper disposal containers down there (such as in public toilets).

"You're more likely to get people to use disposal units if there are enough of them around.

"I just really wish people who have those kinds of habits would think about the consequences of leaving that kind of thing behind."
