Jarryd Hayne is making headlines again, this time over being caught up in an incident in which pornographic images were shown at a school.

The rugby league star was presenting an online safety talk alongside Norton Security's Nick Savvides at a Gold Coast High School when his online browsing was shown to students on a big screen.

Things got a lot more embarrassing when a different device entered an open network, displaying an adults-only website on top of Hayne's.
