In an emotional Facebook post, Everett's father, Tick, suggested those who had persecuted the teenager attend her funeral, which was held on Friday morning in Katherine, a cattle-ranching town in the remote Northern Territory.
Entire families came dressed in blue - Dolly's favourite colour - and some even donned Akubras in a nod to her being the face of advertisements years ago.
"That was Dolly to a tee".
The government had established an eSafety Commissioner to tackle cyberbullying and to work with internet companies to promote online safety, Turnbull said.
Prime Minister Malcolm Turnbull has also seized on Dolly's death to urge for more action on bullying.
"I wholeheartedly support Katrina's quest to keep our kids safe and will be in her corner for the fight. She was just gorgeous".
"This powerful message tells the dark, scary place our handsome angel had travelled to", her father, mother and sister said in a statement.
"They are not alone - there is a Global alliance of people that want to help support and empower", she said in response to a question on Twitter.
"Sometimes, much to my disgust, I'd come home and there would be another poddy on the veranda".
'Thank you to everyone for the overwhelming love and support that the family received over the last few days.
They had expected 50-60 people at the funeral, not the hundreds that turned out.
The shock of Dolly's tragedy has touched hearts and reminded many to check in with children and teens who may be suffering in silence.
'We realise many people have travelled a long way to be with us today and we appreciate everyone who came along today to say farewell.
"We realise there are still going to be kids slip through the cracks - that's life - but we've got to save as many as we can".
They have said that they hope to establish a trust called "Dolly's Dream" which would raise awareness about anxiety, depression and suicide among the youth.
"Our daughter Dolly was the kindest, caring, lovely soul and she was always caring for animals, small children, other children at boarding school who were less fortunate than herself", the family said.
Michelle Pearson said the suicide of Dolly brought back many hard memories about her son.

Dolly's parents expressed gratitude for the "overwhelming response" they received to their grief and asked for time to celebrate the life of their attractive daughter.
Speaking to media after Friday's service, Tick and Kate, as well as Dolly's sister Meg, said they would remember Dolly as "a kind, gentle and loving little girl who loved her animals and cared so deeply for other people less fortunate then her".
'It won't bring our Dolly back, but it may just prevent the loss of another young life.
