The funeral for Ayen Chol, killed after the pit bull entered the home where her family was staying, was held on Friday.
In a eulogy in front of her small white coffin adorned with flowers, a family friend said Ayen would be sorely missed.
"She was a beautiful little girl with a great sense of humour and a great sense of fun," he said.
He said Ayen's legacy was that politicians, journalists, community leaders and people of different nationalities had been united by her death.
"You have brought the entire community together like no one else has," he said.
The Catholic service was conducted in English, Arabic and Dinka, a language spoken in South Sudan from where the family had fled before they arrived in Australia in 2004.
Father Noel Brady from the Resurrection Parish said Ayen was known to be generous, dividing up lollies she was given to share them with her two brothers.
But the manner of her death was so horrific her family would be scarred forever, Fr Brady said.
"You only have got to close your eyes and try to imagine the scene," he said.
"Tears well up in your eyes."
As many as seven children were in the home when the dog entered on August 17, but the animal went for Ayen and her five-year-old cousin Nyadeng Goaer.
Ayen is thought to have died almost immediately during the attack.
Nyadeng received head injuries, and Nyadeng's mother suffered bites on her hands and arm.
Ayen's mother Jacklin Ancatto and her children were living with relatives because their house had burned down.
The dead girl's father, Mawien Chol Monjang, was in South Sudan running an education program when the attack occurred.
The mauling has reignited debate about whether pit bulls are too dangerous to be kept as pets.
After the service family friend Angelo Kout Garang said the family was still shaken up by the death
"Ayen's family is one of the most strong families I have seen ... that strength has supported those mourning with them," he said.
Mr Garang said the family wanted justice for the death of their daughter.
"The mother, the relatives, would want some action taken if the action of the dog itself is attributed to owner's negligence," Mr Garang said.
"The law must serve its purpose," he added.
About 500 people attended the service followed by a burial at Altona Memorial Park.
