Unmarked silver canisters like these have been washing up on beaches along the Australian coastline for more than a decade.
They are filled with aluminium phosphide pellets and can be fatal to ingest or inhale.
What to do if you find a silver canister
- DO NOT TOUCH IT. Stand upwind to avoid possible inhalation.
- Mark the area with sticks and brightly coloured tape.
- Alert the clean-up coordinator immediately or call 000.
