He broke down as he began to tell of the horror of that night.
Mr Lale said his uncle had been living in the home for two months because his Aunty Neti had wanted to look after her two sisters, who needed around the clock medical care.
One had chronic diabetes and the other was on kidney dialysis, he said.
"She would do so on top of caring for five children," he said.
"On the night of the fire ... Uncle 'Miah and the family had made solid plans to move out the very next day.
"They'd been successful in obtaining a rental property which was nearby the Kingston house.
"As they celebrated on that evening the children were rejoicing and happy that they had found a place that they were able to reside in and get some normality back into their lives.
"But on that dreadful evening, the good Lord had plans for our family."
Another cousin, Betsy Neal, said the family couldn't express their heartbreak and urged assembled reporters to be careful with the words they used when reporting the fire.
"It's still very, very raw for us," she said.
"It was just the worst call you ever get.
"We just pray that nobody ever has to experience that."
The younger Mr Lale told of his uncle's desperate fight to save his family after he heard their screams in the dark, smoke-filled house.
He said his uncle had rushed to the room where he'd told his wife to gather the kids, but they were not there.
He ran through the house trying to find them, but could not, and the screaming had stopped.
The older Mr Lale told how he leapt from a second storey window when the cries fell silent, believing his family had made it out ahead of him.
"There was nothing I could do inside the house, the fire and the smoke," the grieving father and husband said.
"I keep calling my wife's name, my boys, my girls, no one answered.
"At that time, I thought to myself they are already outside. They've jumped from the window.
"I ran calling my wife and my kids - no one there.
"No one answers and I realised that at that time my wife and my kids, they can't make it."
"If I knew my wife and kids not outside the house, there's no way I'm going to leave them in there. I'm going to stay inside the house with them.
"My wife, she took all my kids and leave me behind."
Ms Neal said she was grateful her uncle Jeremiah had survived the fire, even if he wished he had died too.
"I thank God that he spared those three men ... in his goodness he did that," she said.
The younger Mr Lale said every family should be reminded to hold their children close.
"If you have you children and your loved ones, you cuddle them and you love them and you tell them you love them," he said.
"Don't take anything for granted.
"I know that sounds cliched but don't let any rift ... happen between your families, go and reconcile with them and love one another and hold onto your loved ones."
Mr Lale also stressed that although two other families were involved - the Taufas and Matauinas - they were one family.
The fact that every child in the home was half Samoan and half Tongan showed how strong the bond between the two islands was, he said.
He thanked the Premier Anna Bligh, Queensland police and other emergency services, church groups including the Salvation Army, and the public who had reached out to the family with donations.
He acknowledged the schools in the community, and asked for forgiveness for anyone he had neglected, asking they blame his head rather than his heart.
Detective Inspector Chris Jory told reporters his officers were yet to fully interview all the survivors and witnesses because of the sensitive nature of the work.
The family had received a threat recently that a house - not necessarily theirs - would be burnt down.
But police had interviewed the person responsible and ruled them out, he said.
"There is no suggestion of foul play," Det Insp Jory said.
"We have a version from Misi (Matauina) and it's consistent with that of the other survivors."
Preliminary findings had so far found the fire started on the lower level of the home, possibly in an office area.
Superintendent Noel Powers later told AAP the grandfather, Tau Taufa, had been working downstairs in the office area, went upstairs to have a shower and when he came back downstairs, found the office ablaze.
The flames were too big for him to beat down, so he tried to raise the alarm instead.
None of the home's gas cylinders, which have been blamed for the blaze, had exploded, Supt Powers said.
The remaining bodies are expected to be retrieved from the home by noon on Friday, but police investigations at the scene could take some days yet.
