Eight years after Amy Everett became the face of iconic hat brand Akubra, her life was tragically cut short.
Mr Everett, Dolly's mother Kate, sister Meg and family and friends packed into Casuarina St Primary School after midday on Friday.
"I wholeheartedly support Katrina's quest to keep our kids safe and will be in her corner for the fight".
'It was just so sad.
"We are not concerned with the who or the why of who pushed our daughter to this point, we just want to save another family going through the sadness and tragedy that our family is experiencing".
Dolly's death caused shock across Australia, with Prime Minister Malcolm Turnbull pledging to do more to tackle cyberbullying and raise awareness of the dangers.
'Dolly, you are loved and you will never be forgotten, ' he said in a Facebook post.
Mr Everett said the family was overwhelmed and humbled by the outpouring of support.
'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.
"Our daughter Dolly was the kindest, caring, handsome soul and she was always caring for animals, small children, other children at boarding school who were less fortunate than herself", the family said.
'Farewell to our handsome daughter and our lovely little sister Dolly.
'They are celebrating Dolly's life in Toowoomba, Warwick and other parts of the country. It is up to us to stand up when we see any kind of bullying behaviour.
"She was loved by so many and made friends with everyone she came across".
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.
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.
Dolly saw the good in this world and the good in everybody she met.
"It shouldn't have taken the loss of a young life to drive this change, but is where our journey will start".
"Being in a salon we talk to a lot of people every day and people open up to us about their problems and I think it's nice to be able to do that", she said.
The family shared a drawing by Dolly of a skinny figure bent over backwards with the words, "speak even if your voice shakes" in bold, which she'd completed before taking her own life on January 3.
"This powerful message tells the dark, scary place our lovely angel had traveled to", the family wrote.
