A Queensland farm on the Darling Downs has become the unlikely testing ground of one of the most technologically advanced Google projects that could see autonomous drones deliver anything from chocolate to life-saving medicines.

Google X, a division of the US-based technology company dedicated to making major technological advancements, tested Project Wing near Warwick earlier this month, the first time "non-Googlers" had been involved.

Google X director Astro Teller said Project Wing's goal was ultimately to build a system for delivering small and medium sized packages within minutes to anyone, using self-flying vehicles.

"There's no reason we should all have a power drill in our garage when, at any one time, the world is using one hundredth of a per cent of its power drills," he said from the company's headquarters in California.
