Distraught children and parents have added to the growing pile of bouquets, balloons and messages of condolence that have been laid in tribute following the tragedy at Banksia Road Primary School in Greenacre on Tuesday morning.
Two eight-year-old girls and a nine-year-old girl remain in hospital in a stable condition, a Westmead Children's Hospital spokesman said.
Senior staff and counsellors greeted parents and pupils at the front gates on Wednesday.
Local MP and former principal of Punchbowl High School, Jihad Dib, visited the school and said the tragedy was
"unimaginable".
"When you drop your child off to school, this is the last thing you could ever imagine even happening.
"There's a huge amount of disbelief still but it's really good there are counsellors and chaplains, all the support mechanisms that we could provide to help people go through this.
"For the time being, the most significant thing is the fact that people are standing together and supporting one another. The principal and his staff are doing a magnificent job."
Local resident Nadia Abdul wept as she recalled memories of the two boys who she often saw at the lolly shop where she worked.
"They were both beautiful children. They were absolute angels," she said.
"I cannot imagine what the families are going through. My heart is breaking for them."
Remas, accompanied by her aunty Eman Fayed, described the moment when her principal confirmed the deaths.
"When I first realised it, I was shaking," Remas said as she broke down. "And it's really hard."
Ms Fayed was one of the first relatives at the school after the crash and said the hardest part was waiting for news about the injured children.

"You think this is the safest place to send them," she said.
"What can you do? You have to pray."
Prayer also formed part of the answer for Steve Sleiman's young family as they tried to explain the tragedy to their kids.
His eldest son asked his wife why God would do such a thing.
"We just lift their spirits up," he told reporters at the school gate.
"I'm shocked. To think a child dies at school - everyone knows what I'm talking about."
The principal and chaplain of the nearby Islamic school met with the state school's staff on Wednesday morning.
"We have to try our best to support each other," Malek Fahd Islamic School chaplain Fawaz Kamaz said.
"The thing about Australia is that we all come together no matter of religion or background in time of tragedy."
The tributes adorning the school fence promise the children will never be forgotten.
"A good heart has stopped beating, a good soul has ascended to heaven," one message said.
The 52-year-old woman driver of the SUV at the centre of the tragedy has asked for forgiveness through her lawyer.
Her licence was suspended and she was granted conditional bail ahead of an appearance at Bankstown Local Court on November 29.
The lawyer also told The Daily Telegraph she was "deeply sorry for the loss and hurt suffered by the children, the school, the families and the community".
The boys were pinned underneath the car after it smashed through the wall of the weatherboard classroom with 24 pupils inside.
