This isn’t something that’s decades down the track, it’s started happening in parts of Australia already!
The Australian Civil Aviation Safety Authority (CASA) have permitted Wing (a company owned by Google or Alphabet Inc as the head company is now called after a company restructure) to fly delivery drones in certain suburbs in Canberra and in Logan, Queensland. See the following link for more information on the approval from CASA – Drone delivery systems – CASA.
It’s really important to think outside of the box as to how this might be able to work for your business in the future. The current businesses Wing is delivering for includes some businesses you might not have thought suitable for drone deliveries such as a gelato shop, Bakers Delight, coffee shop, and a hardware & supplies store. See the following link for a list of the Canberra businesses using Wing – Canberra – Australia – Wing. Also, look at the short video in the following link to get you thinking about how drones could be utilised in your business – Wing.
