The children are believed to be under five years old, while the woman is thought to be in her 40s. Formal identification has not yet been completed.
The woman and children are understood to have been at the location for only a few minutes when passing cyclists noticed them and began providing first aid.
Police contacted the children’s father while he was at work.
“We’ve made contact with the father and obviously you can imagine receiving that tragic news,” Superintendent John Nelson said.
“That person is at work just going about their business and they’ve had this information provided to them.”
Police have not confirmed the woman’s relationship to the children, but said she was not previously known to them.
A crime scene has been established while detectives investigate the circumstances surrounding the Blue Mountains incident.
The woman and the two surviving children underwent emergency surgery and remained in critical condition on Sunday night.

‘Let me just say it’s obviously been a very difficult weekend, a very distressing weekend for many people,’ he said.
‘This is the fourth death that we’ve had, potentially domestic violence-related.’
