New Zealand has produced a series of advertisements about staying safe online. This one about online grooming is funny but creepy at the same time. You can find out more at https://www.keepitrealonline.govt.nz. If you are in Australia, you can report online grooming at https://www.accce.gov.au - the Australian Centre to Counter Child Exploitation. The safety commissioner has information on cat fishing (someone pretending to be someone they're not) at https://www.esafety.gov.au. If you suspect that someone is catfishing or grooming, talk to a trusted adult. Take screenshots of conversations as evidence. Stay safe.
