Medical technology: ultrasound, bionic ear, pacemaker, anti-flu medication
Australia has made significant contributions to medical technology, including ultrasound, the bionic ear, pacemakers, and anti-flu medication.
Ultrasound technology in Australia began in 1959 with the establishment of an Ultrasound Research Section within the Commonwealth Acoustic Laboratories. By the 1970s, this group had become one of the leading ultrasound research organizations in the world and contributed significantly to the development of ultrasound technology and its clinical applications.
The bionic ear, or cochlear implant, was invented by Professor Graeme Clark of the University of Melbourne in 1979. This invention was the first major advancement in the treatment of deafness since the introduction of sign language. The implant reliably gave speech understanding to severely and profoundly deaf people and provided spoken language to children born deaf.
Australia has also played a crucial role in the development of pacemakers. While the first cardiac pacemaker was built by Dr Albert Hyman in New York in 1932, he acknowledged that Dr Mark Lidwell in Sydney, Australia, had built a pacemaker and successfully used it to resuscitate a newborn infant in or before 1929. Additionally, an Australian company, Telectronics, founded in 1963, designed many features of transvenous leads and pulse generators that are still used today.
In 1996, a team of scientists at the Victorian College of Pharmacy at Monash University in Melbourne developed Relenza, an anti-flu medication. This medication was discovered as part of a project by the Australian biotechnology company Biota to develop antiviral agents through rational drug design.

Refrigeration: James Harrison's vapour compression refrigerator
James Harrison's vapour compression refrigerator has been credited as one of the world's most significant inventions, and it all started with a journalist's observation. In 1856, Geelong newspaperman James Harrison noticed the cooling effect of ether on his typewriter keys. This sparked an idea that would revolutionise food handling and storage forever.
Harrison's system of vapour compression refrigeration was a groundbreaking innovation. By utilising the principle of vapour compression, he created the world's first practical ice-making machine and refrigerator. This invention was so significant that it earned him a trip to London that same year to patent his creation, which is still the basis for modern refrigeration today.
The refrigerator, as we know it today, is an enhanced version of Harrison's original concept. While the mechanism has been significantly improved, the core idea of using vapour compression for cooling remains the same. This invention has had an immense impact on daily life, and its legacy can be seen every time we open our fridges.
In addition to his refrigeration system, Harrison also invented and commercialised an ice-making machine. This invention further solidified his legacy in the field of cooling technology and earned him recognition as a pioneer in the field. Harrison's contributions to refrigeration have left an indelible mark on history, and his ideas continue to keep our food fresh and our drinks cold.
Australia has a history of innovation, and James Harrison's story is just one example of how ingenuity and observation can lead to inventions that change the world. From the simple observation of ether's cooling effect, Harrison created a technology that has become a staple in households worldwide. His story serves as an inspiration for future innovators and a reminder of the power of Australian inventiveness.

Transport: car radio, crankless engine, winged keel, plastic bank notes
Car Radio
The idea of installing a radio in a car was explored in the early 1920s by various radio enthusiasts and engineers. The Motorola 5T71 was the first commercially available car radio, costing USD$130, which was about one-fifth the price of a car at the time.
Crankless Engine
The crankless engine was invented in 1917 by British-born Australian resident Anthony George Maldon Michell. Crankless Engines (Aust) Pty Ltd was formed in Melbourne in 1920 to develop and manufacture Michell's engine design. The crankless design was eventually used for gas engines and compressors, but its use in motor vehicles failed to generate interest.
Winged Keel
The winged keel is a sailboat keel layout that was first fitted on the 12-metre class yacht Australia II, which won the 1983 America's Cup. The layout was adopted by Ben Lexcen, the designer of Australia II. The winged keel, along with the yacht's efficient sail design, contributed to its success. Winged keels are generally found on high-performance sailboats if they are not prohibited by class rules. They are particularly advantageous for heavy yachts with a lot of sail area.
Plastic Bank Notes
Modern polymer banknotes were first developed by the Reserve Bank of Australia (RBA) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). They were first issued as currency in Australia during its bicentennial year in 1988. By 1996, the Australian dollar had been completely switched to polymer banknotes. Polymer banknotes last significantly longer than paper notes, resulting in a decreased environmental impact and reduced production and replacement costs.

Food and drink: Vegemite, boxed wine, plastic currency
Australia has a diverse range of food and drinks, with foreign cuisines such as pizza, curry, and dumplings transforming into stable dishes. However, there are still some popular dishes and drinks that Australia has invented.
Vegemite, a staple in Australian cuisine, is often slathered on toast and paired with a cup of tea or coffee. The yeast spread was developed by Cyril Callister in Melbourne in 1922.
Boxed wine, also known as cask wine, was invented by South Australian winemaker Thomas Angove in 1964. It is now a more affordable and environmentally friendly alternative to traditional bottles.
Australia also has a strong coffee culture, with many independent cafes and homegrown franchises. The flat white, a coffee made with a double espresso, steamed milk, and a thin layer of microfoam, was first documented in Sydney in 1985. While New Zealand has also claimed the invention, Australia has a strong case, with documentary evidence of the drink's existence there preceding New Zealand's.
Other notable Australian food and drink inventions include the lamington cake, pavlova, Jaffles, Milo, and Anzac biscuits.

Communication: Wi-Fi, Google Maps, Baby Safety Capsule
Australia has a history of innovation, from the very old to the very new. The country's inventiveness may spring from its geography and isolation as an island continent. Australians have been leaders in inventions relating to maritime and aeronautical matters, as well as agriculture and mining.
Wi-Fi
In the 1990s, a team of Australian inventors created the technology for high-speed wireless data delivery between devices over a network, now known as Wi-Fi. The team, made up of John O'Sullivan, Terence Percival, Graham Daniels, Diethelm Ostry, and John Deane, developed a wireless LAN with speeds matching its cable contemporaries. O'Sullivan was awarded the Prime Minister's Award for Science in 2009. The Australian government agencies have suggested that "nearly a billion people" use his invention every day.
Google Maps
Google Maps was created by two Denmark-born but Sydney-based developers, brothers Lars and Jens Rasmussen. In 2003, they co-founded a startup mapping company called Where 2 Technologies, which they sold to Google in 2004, which later became Google Maps.
Baby Safety Capsule
In the 1970s, Australian state governments made the wearing of car seat belts compulsory, and a variety of child restraints came on the market. However, there was no secure way to protect babies in a crash until 1984, when the Baby Safety Capsule was designed. Invented by Richard Boyson Heath and Colin Michael Nagel, employees of Rainsfords (later Britax Rainsfords, part of Britax International), the capsule consists of a bassinette inside a base that can be secured by a seat belt. The bassinette can rotate in a crash, keeping the baby more upright and distributing forces uniformly over its body, while also pushing against an impact-absorbing bubble in the base. The capsule was designed to fit in an adult seat space, and it could be removed from the base to carry the baby outside the car. Since 1984, over 2 million Australian babies have been protected by the Baby Safety Capsule.
