Keep a sighting controlled
Move children, pets and bystanders to a secure place. Watch only from a window, fence or other safe barrier if you can. Tell the catcher when and where you last saw the animal and which way it moved. Do not lift pots, open sheds, reach into drains, try to identify it at close range, trap it or kill it.
If it disappears
Prevent access to the last-seen area. A search through concealed ground, stacked materials or a drain is unsafe. If the snake is inside a room, close a door only when you can do so without approaching it.
Regional species, not a local record
The Australian Museum describes eastern brown snakes in open and modified environments, while its red-bellied black snake account associates that species more with moist habitat. These are regional possibilities, not confirmed Stanhope Gardens animals. Colour is not a safe identification method.
