Quick field context
What the profile can—and cannot—tell you
Habitat: Bushland, roof spaces, trees and rocky shelter.
Risk summary: Non-venomous. A web page cannot reliably identify a snake from a hurried glance, and colour can change with age, light and individual variation.
Keep several metres back, move children and pets away, and note the last position. Do not try to turn over cover, block an escape route or collect the snake.
