A striking new ad about cyberbullying, directed by a 15-year-old girl, has been lauded as "brave", "disturbing" and "relevant" less than two years after the suicide of Amy 'Dolly' Everett shocked the nation.

Film shows a girl receiving texts like "kill urself" as oblivious parents sit by Dolly's parents hope it shows others how cyberbullying can creep into the home

Dolly's parents hope it shows others how cyberbullying can creep into the home Film's teen director says every high schooler on social media has experience with it

Dolly was just 14 when she died early last year after being tormented by cyberbullies.

Now, stirred by her death, teenager Charlotte McLaverty has created a powerful short film that depicts how modern bullying is more than just sticks and stones in the playground.

It follows a teen girl in school uniform holding her phone, which pings with the notification sound every time another girl throws a rock at her.

The settings are all at home, including in the bedroom, bathroom and around the kitchen table as oblivious parents sit by.

As the film goes on more kids are given stones to throw and texts rapidly appear on the victim's phone, with messages like "why don't u just go kill urself".

"I was hoping to relate to how it feels to be cyberbullied for most teens," Charlotte told the ABC.

"The rocks being thrown was like the visual representation of what it feels like.

"The fact that the bully is there with her and none of the parents or children realise what's happening."

One in five young people report being cyberbullied in any one year, according to research by the advocacy organisation Dolly's Dream, which was established by Dolly's parents last year.

The organisation has this week launched a new internet hub to help parents better understand and deal with online safety, including bullying.

Australia's eSafety Commissioner, Julie Inman Grant, also operates a cyberbullying reporting scheme for people aged 18 or under, and can issue an order to have material taken down.

Since July 2015 it has handled more than 1,300 complaints about cyberbullying of young Australians and says it has had a 100 per cent compliance rate from social media sites.

Dolly's mum Kate Everett said she hoped the ad would inspire teens to speak up.

"Dolly left us with a message that was 'speak, even if your voice shakes'," she said.

"I hope it reveals to parents how cyberbullying can happen anywhere, even at the dining table or watching TV with the family."

'Not like a punch in the face'

Charlotte's ad is being billed as a project that is "by teens, for teens" and she said part of the problem was cyberbullying was sometimes missed, even by the victims.

"It's not like a punch in the face. It's constant, relentless comments," she said.

"And it's harder to know — a punch in the face is like, 'Oh I'm being bullied'. You come home with a black eye.

"These type of comments, it's such a grey area, it's hard to know if you're even being cyberbullied, but you're hurt."

"It's so difficult, that's why we need to start talking."

Charlotte said the technology hadn't been around long enough to know if the issue had become better or worse, but she was adamant it was pervasive.

"Everyone who's had social media for over a year has either witnessed, experienced or been a victim or a bully," she said.

"Everyone who has social media can have some sort of story about it."

The ad was publicly released this week but has already been welcomed by viewers who described it as "so relevant" and "fantastic", with some saying it should be shown in every high school.

"Powerful and disturbing ... it's sad that this happens and brave that this has been made," one person wrote in response.

"The young girl who created this represents the situation so accurately," wrote another.

The film ends with the victim catching one of the thrown rocks and staring down her bully.

"Just to give a little bit of hope at the end of the film," Charlotte said.
