Video tributes from Rooster Connor Watson and Swan Dane Rampe were played, thanking Mr Davies for his support.
Mr Davies' profound impact on community, friends and family was clear.
His uncle Derek referred to him as "Lukey Boy", a common theme in many tributes shared.
"He never had a photo showing his bad side and as we've all come to learn, he never had one," his Uncle Derek said on behalf of Mr Davies' brother, John.
"Those tender years of us growing up as a family taking care of each other and the bonds we shared as the closest brothers will be my most precious memories."

Stuart Crichton, who taught Mr Davies in year six at Greenbank State School said the darkness of his death would not overshadow his light, kindness and positive impact on others.
"He was more than a student to us," Mr Crichton said.
"He had embedded himself into our hearts, and had impacted positively on our pedagogical craft.
"He was cherished."
