From world-changing and life-saving medical developments to inventions that have brought the world closer together. For sure, one more reason to be proud of.

Here are three Australian inventions that changed the world.

Black Box Flight Recorder

The black box flight recorder has helped make commercial air travel the world’s safest form of travel. It was invented by Australian scientist Dr David Warren, who lost his father to an aircraft tragedy in 1934.

Warren did not have the resources for a flight-recorder project at the time. Still, a decade later, when he had established a presence at the Aeronautical Research Laboratories in Melbourne, he thought it would be good to record the final moments of a crashed plane’s last flight to avoid other accidents.

Electronic Pacemaker

A pacemaker is a medical device inserted into a human’s chest, just under the skin, to pace the heart.

The first pacemaker was invented by Australian doctors Mark Lidwill and Edgar Booth in the 1920s. Now, more than three million people worldwide rely on pacemakers to keep their hearts beating properly.

Google Maps

Danish brothers Lars and Jens Rasmussen created Google Maps in Sydney in the early 2000s with Australians Neil Gordon and Stephen Ma. The four men founded Where 2 Technologies in 2003, which became Google Maps when the internet company bought them.
