Superintendent John Nelson told reporters it was a “very tragic scene”.
“At this stage, the father is helping with our inquiries, so he is the one who has contacted our police,” he said.


A 42-year-old woman was taken to Westmead Hospital under police guard in a stable condition.
The woman and children are not believed to be known to police.
Police say there is no ongoing threat to the community.
A “thorough” police investigation is underway, Police Commissioner Karen Webb said in a press conference on Tuesday afternoon.
Nelson added there will be lots of support services available for first responders as well as those at the children’s school.
“This is about as tragic as it gets,” he said.
“The Blue Mountains is a very peaceful community, and they will all be in genuine shock.”
Footage showed homicide detectives combing the scene on Tuesday afternoon.


Mayor of the Blue Mountains Mark Greenhill said his community “lost two precious souls in the most awful circumstances”.
“Now is a time to come together and remember these two beautiful children and their extended family, whose grief must be as unimaginable,” he said.
A homicide investigation is underway.
Anyone with information is urged to contact Crime Stoppers.
