The drones will only be allowed to fly during the day and not before 08:00 AEST at the weekend.They will not be allowed to fly over crowds or main roads.Trials of the drones had attracted complaints from residents in Bonython, Canberra, who said they were noisy and intrusive.The Bonython Against Drones campaign said the devices could be heard from "a long way off, both coming and leaving"."When they do a delivery drop they hover over the site and it sounds like an extremely loud, squealing vacuum cleaner," the group said on its website.In response, Wing said it had developed a quieter drone.

The aviation authority says Wing must use this quieter drone for its commercial service.
