You may not be able to imagine what would happen if there was no refrigerator at home? How will you preserve food, milk and fresh meat? In 1856, Australian James Harrison used a vapor compression system to create the world's first practical ice machine. However, the refrigerator he first invented at that time was not what it looks like today.

Also in 1856, Melbourne's masons fought for the "eight-hour day", that is, eight hours of work, eight hours of rest, and eight hours of entertainment. Australian James Galloway (James Galloway) finally introduced this concept to success. On April 1856, 4, the masons at the University of Melbourne stopped their work and led other masons to join them and march towards the Houses of Parliament. A few weeks later, the eight-hour working day was determined.

Although you may not have seen this Australian invention, it has saved many lives. It was the "black box" flight recorder invented by David Warren in 1958. The "black box" can record all flight instrument details and the voice of the pilot. When accidents happen in the air, investigators can find out what happened at that time and how to avoid these unfortunate incidents in the future, all thanks to the invention of the "black box".

For Rod Saunders (Rod Saunders), 1979 was his happiest moment. That year, with the help of a cochlear implant invented by Professor Graeme Clark at the Royal Victorian Eye and Ear Hospital in Melbourne, he was deaf and heard. The bionic ear may be one of Australia's biggest inventions, changing the fate of patients with hearing problems in the world.
