A tight-knit community is reeling after a kindergarten student and her baby brother were killed when a SUV collided with a pram shortly after school pick-up.
The girl and her brother have been identified as Katherine, 5, and Harry, aged 14 months - the only two children of 33-year-old mother Sok Ram.
The children were struck by the vehicle while crossing a street with their mother in Cabramatta, in Sydney's southwest, about 3.15pm on Wednesday.
Katherine was in her first year of kindergarten and had just been picked up after receiving an award, according to an online fundraiser on the family's behalf.
The children's lives were taken in a "split second", the man behind the fundraiser, Patrick Te, said.
"As they were crossing the road together, heading back to the car, an oncoming vehicle suddenly struck both Katherine and the pram where Harry was sitting," he said.
