Medical significance
The sources checked document venom but do not establish species-specific effects in people. Treat any possible bite as an emergency and call 000.
What to do if you encounter one
Keep your distance and leave the snake a clear route away. Do not handle it, chase it for a photograph or attempt to inspect its mouth. If it is inside a building, keep people and pets clear and contact a qualified local snake catcher.
