Aviation Security officers removed more than 190,000 batteries from passengers' bags last year.

That figure included about 10,000 vapes taken from checked-in baggage.

Other items that must not be checked in, but carried onto the plane include powerbanks, airpods and airpod chargers, and loose or spare batteries.

Aviation Security Service group manager operations Karen Urwin told Midday Report's Charlotte Cook what happens to the confiscated devices and why lithium batteries are so risky.
