The islands' Council supported National Child Sexual Exploitation Awareness Day yesterday.
The campaign aims to highlight the issues surrounding CSE, with events on the internet and across the UK.
Jennie Woodcock, who works in Children's Social Care on the islands, told Radio Scilly: "The charity NWG started off this big campaign a few years ago and they're doing lots of work and different activities with police and councils all up and down the country. Some are doing school assemblies, some are going on to local radio stations and doing lots of campaigns on Facebook and Twitter.
"The big Facebook campaign is where people write a pledge on their hands, take a photo of it and put it on their Facebook page to help raise awareness. There's also the hashtag #helpinghands on Twitter."
She urged children to take care of themselves and be aware of internet safety, especially if anyone asks them to post photos of themselves.
Possible danger signs for parents to look for include a child suddenly having a new mobile phone or more cash, or if they are acting differently to usual, for instance being more withdrawn or staying out later.
Last year the police delivered CSE awareness training to various local businesses. Tia Thompson also won a competition among secondary school pupils to design a window sticker to show which establishments had received the training (pictured below).
Anyone with concerns is asked to contact Children's Social Care (01720 422483) or the police (422444).
