He was treated but died at the scene.

Tearful neighbours said the man in his 50s was "the sweetest person" and told 9News they were "very sad".

Police officers from Auburn arrested a 32-year-old man, identified as Rory Schade, soon after on nearby South Parade.

He was taken to Auburn police station where he was charged with murder.

Officers said the men knew each other.

9News understands the pair were in a relationship.
