SYDNEY (AFP) - Australia will introduce new surveillance technology for a crackdown on drones next year, aviation authorities said on Monday (Dec 24), as concerns mount over their increasing prevalence in public areas.

Australia's Civil Aviation Safety Authority (CASA) plans to roll out new monitoring equipment at major airports across the country next month.

The technology has the ability to identify a drone, its serial number and the location of the controller while in flight, CASA communications manager Peter Gibson told AFP.

"We can identify, therefore, who is flying it," he said.

The technology, coupled with new registration requirements, will dramatically change the way rules relating to drones are enforced, Mr Gibson added.

"2019 will be a drone safety crackdown," he said.

While the new equipment has been planned for some time, the incident last week at London's Gatwick airport - which saw nearly 140,000 passengers affected by three days of disruption after reports of drone sightings - "highlights the importance of having this capability", Mr Gibson said.

Officials will also roll out a drone registration scheme in mid-2019, so that authorities can better track who is flying them and advise of proper safety precautions.

The new mobile tracking technology will be used in "known drone hotspots" such as the Sydney Harbour Bridge, which has seen a concerning rise of drones operating in a restricted area, Mr Gibson said.

The authorities will have greater powers to conduct safety checks, he said, and increased ability to issue fines of up to A$10,000 (S$9,690) for those in breach of the rules.

"In 2019, it could be very expensive doing the wrong thing with your drone," Mr Gibson said.
