Keep drones away from Anzac events: CASA

Drone operators keen for footage of Anzac Day events are being warned to steer clear of Monday's celebrations.

Flight safety regulations dictate drones are not to be flown near or over groups or within a 30-metre radius of people, the Civil Aviation Safety Authority says.

CASA is concerned about the risk drones pose to low-flying ex-military aircraft used during celebrations.

"In simple terms, drones must be kept well away from people and aircraft and they must not be flown in a way that causes a hazard," CASA director of aviation safety Mark Skidmore said.
