Hundreds gathered for the memorial of Amy "Dolly" Everett after the Northern Territory teenager took her own life to escape bullying.
The father of a 14-year-old girl who took her own life after being bullied has urged parents to talk to their children.
Amy "Dolly" Everett's father, Tick, made the plea to parents during an emotional statement after his daughter's memorial in the Northern Territory.
"Please just talk to your children and anybody else and remember, speak even if your voice shakes. Stop bullying and be kind and do it for Dolly," he said.
Mr Everett said the family would remember Dolly "as a kind, gentle and loving little girl … (who) saw the good in this world and the good in everybody she met".
The family also announced they would be setting up a trust called Dolly's Dream to raise awareness of bullying, anxiety, depression and youth suicide.
"It won't bring our Dolly back, but it may just prevent the loss of another young life," Mr Everett said.
"It should not have taken the loss of a young life to drive this change but this is where our journey will start."
Mr Everett said he would "fly to every school if I could" to raise awareness of these issues.
Hundreds of mourners gathered at the Casuarina Street Public School in Katherine on Friday to farewell Dolly, with supporters heeding the call to wear the 14-year-old's favourite colour, blue.
Local businesses and cars have been covered in signs and stickers with the hashtags #dollysdream and #speakevenifyourvoiceshakes - the name of the anti-bullying trust set up by her family and the later Dolly's own words on speaking up.
Dolly's Warwick-based school Scots PGC College, southwest of Brisbane, flew its flag at half mast today and will host a commemorative service in term one.
Meanwhile a friend of Dolly said she had been left asking whether she could have done anything to prevent the 14-year-old's suicide.
Taniesha Southeron said she and others had been questioning themselves after Dolly's death.
"I think everyone who knew Dolly when they found out what happened, they would have asked themselves, 'was there something I could do?'" Ms Southeron told the Seven Network.
"Did I miss something? Did I not see something? Did I say something wrong? Has she taken something I've said in the wrong way? It's very hard for all of us. I know we've all ask ourselves those questions."
On Sunday, Mr Everett also called on his daughter's bullies to attend the memorial.
"Please come to our service and witness the complete devastation you have created," Mr Everett wrote.
His daughter's death has sparked a battle cry among concerned parents and others, prompting a Queensland mother to launch a campaign to shut down an app that was used to bully her own daughter.
"I do not want my daughter or any other to become the next Dolly," Katrina wrote in the change.org petition, which has already received more than 31,000 signatures.
The Rockhampton mother, known only as Katrina, called on Apple's App Store and Google Play to stop downloads of Sarahah, which allows people to leave anonymous feedback for each another.
Sarahah's website said the app, "helps you in discovering your strengths and areas for improvement by receiving honest feedback from your employees and your friends in a private manner."
Katrina said her daughter doesn't have the app, but was "shattered" after seeing a message written about her.
"My daughter doesn't even have this app, but these bullies sent it to her friend about her, saying she should kill herself and that everyone would be so much happier and that everyone hates her," Katrina told The Courier-Mail.
Prime Minister Malcolm Turnbull has also seized on Dolly's death to call for more action on cyber-bullying.
"Every step must be taken to reduce the incidence of bullying, whether offline or on, and eliminate it wherever we can," Mr Turnbull wrote in a comment on Facebook.
Northern Territory Police confirmed they are investigating the circumstances surrounding Dolly's death.
"NT Police can confirm they're investigating all the circumstances surrounding the non-suspicious death of a 14-year-old girl. A report will be prepared for the Coroner," a police spokesperson said.
