Primary school students are "just too trusting" of people online, according to Oxley Police Senior Constable Michelle King.
Ms King delivered the AFP Cyber Safety Presentation to year five and six Tamworth Public students on Monday, before holding a similar workshop for parents of students.
"Kids understand the whole stranger danger thing in the real world, but they can't relate that to online," she said.
"If they get a friend request from someone their own age they just assume that person is who they say they are."
Setting accounts to private, the importance of strong passwords, only accepting friend requests from people they know and not giving out any private information were the key points to the student presentation.
"What you don't do in the real world, you don't do in the online world," Ms King said.
Ms King used the case of Carly Ryan, a 15 year old girl who was groomed online and murdered by a pedophile in 2007, to illustrate the importance of cyber security and privacy.
That case is thought to be the first case of online grooming in Australia, and led to sweeping legal changes known as 'Carly's law.'
In the second presentation parents and carers were also told of the dangers of the internet and social media, and were also reminded of the legal responsibilities that come with providing internet access to children.
Any child under 13 years of age must have parental permission to access services such as Facebook and Instagram, although the responsibility does not stop there.
"Parents have to know children's passwords, and need to know what they are doing online," Ms King said.
"If parents have given a kid internet and a device, and that kid commits an offence then they are liable, and can face legal consequences."
