The eSafety Commissioner website has a range of excellent resources for parents addressing online safety including an online guide which is available in many languages as well as information sheets, videos and audio recordings covering a range of different online safety issues. There are even templates for family tech agreements! Of particular relevance to the parents of teenagers, the online sexual harassment and image-based abuse video provides great information on how you can support your child if they are being abused online.
In addition, there will be some webinars for parents and carers in Term 4 that you can register for; one to support you helping your child to look after their mental health when online, and the other to help you understand the benefits and risks of online gaming.
