Tasmania's sexual assault support services said yesterday that they'd noticed that young people were increasingly reporting to them as victims of revenge porn, which involves people sharing or distributing intimate images of another person without their consent.

According to Kids Helpline, which is run by youth charity yourtown, the organisation has about 150 "contacts" each year regarding "sexual activities online".

The discrepancy between the amount of online traffic its sexting information pages attract and the amount of direct contact it has with people about the issue has prompted Kids Helpline to create a survey on its website in an attempt to get a better understanding from young people about what's happening in their lives.

Kids Helpline's sexting "tip sheets" are now the third most visited parts of its website.

Kids Helpline and yourtown chief executive Tracy Adams said young people's understanding of the consequences of "oversharing" explicit images is "low".

"Navigating damage to reputation through non-consensual sharing of explicit images can ... affect behaviours, emotions and self-identity," she said.

Sexual Assault Support Service training coordinator Peter Baldwin visits schools across Tasmania to discuss respectful relationships and any sex-related questions young people may have.

"We get [told], 'My boyfriend said we're not really boyfriend and girlfriend, unless I send him [a nude]'.

"People have fear that if they don't engage in sexting ... their partner's going to find someone else.

"I'd like to say [sexting] can be done really well [but] it can also be exploited."

The state government is set to table a bill in the coming months to target bullying, which it says will encompass revenge porn offences.
