The Anglican Church opened their doors in Singleton, Branxton, Cessnock as well as the cathedral in Newcastle on Monday to give space to those who wanted to grieve.

"We don't expect people to go to anything and not come home alive, so our hearts are breaking at this impact," Newcastle Bishop Peter Stuart said.

"I want people to know that they're not alone, that people are praying for them."

The Very Reverend Dean Katherine Bowyer said the cathedral saw more visitors than would be normal on a public holiday as people processed the tragedy.

"They're just in shock, just really still trying to process it,"

"This surreal experience that this can't be happening in our community, in our backyard."

On Instagram, one user called for people to put AFL guernseys on their mailboxes as a show of support for the Roosters and Singleton community.
