In 1988, the US military announced to the world that it had developed the Lockheed F-117 Nighthawk stealth fighter, which it believed could not be detected by radar. The stealth fighter had cost more than $11 billion to develop and had been in operation for seven years. Seeing a challenge, Australian scientists at the CSIRO speculated that if the plane could not be detected, perhaps the turbulence it made passing through air could be. $1.5 million later, the Jindalee Radar system had transformed the stealth bomber into nothing more than an unusual looking aircraft.
The invention of the Jindalee Radar System continued a long line of Australian inventiveness. Some of the inventions, such as the notepad and power board, were so simple they beged the question as to why they had never been invented before. Perhaps their invention could be attributed to the liberation from traditional thinking that comes from living in a multicultural society. Whereas other cultures will continue with practices because it is the way things have always been done, in Australia, things are done in a diversity of ways, which makes Australians more inclined to conceive of the best way of doing things rather than just holding onto the past.
Some of the inventions, such as the stump jump plough, refrigerator and dual flush toilet, were in response to Australia's unique environmental conditions. Perhaps their invention could be seen as an example of how different environments present different challenges that require novel solutions.
Some of the inventions, such as powered flight, nuclear fusion, wi-fi internet, penicillin and the Jindalee radar system, could be attributed to a willingness of Australians to collaborate across national boundaries rather than monopolise ideas for nationalistic reasons. By sharing their own ideas, inventors gained access to the ideas of others and were able to achieve what they otherwise might not have.
Finally, some of the inventions, such as the hills hoist, ugg boot, wine cask and inflatable escape slide, could be attributed to a willingness to elevate pragmatism above aesthetic or cultural beauty. Had the inventors worried more about the look of things, perhaps none would have been invented.
Grinding stones – Excavations of Cuddle Springs in north central NSW has found evidence of grinding stones dating back 30,000 years. These predate all other grinding stones around the world by 20,000 years.
The rudder – Rudders provide the means to steer boats in a straight line, particularly in adverse environmental conditions. Ancient Egyptians had a form of a rudder, which was a long paddle hang over one side. It is believed that Ancient Romans and Chinese invented the first stern mounted rudder in the 1st century AD. The Bradshaw paintings (Gwion Gwion) on the walls of the Kimberly, indicate that ancient Australians used stern mounted rudders more than 17,500 years ago.
Could it be a rudder 16,000 years before rudders were believed to have been invented?
Boomerangs – A boomerang is a hunting tool that is constructed as a flat aerofoil designed to spin about an axis perpendicular to the direction of its flight. It allows the hunter to throw a very heavy stick with great accuracy and sufficient power to break the legs of a kangaroo and neck of an emu. Cave paintings in the Kimberly indicate that boomerangs had developed a ceremonial funciton at least 17,500 years.
Didgeridoo – The didgeridoo was traditionally made out of Eucalyptus branch, which was then buried near a termite mound to produce a long hollow piece of wood that can be used a musical and instrument.
Woomera – The woomera is a type of spear thrower, which acts as an extension of the human arm. The extra energy gained from the woomera's use has been calculated as four times that from a compound bow.

invented by Henry Sutton in Ballarat.
1877 Mechanical clippers -Shearing is a backbreaking job but it was even more back breaking when sheep were sheared using scissors. Frederick York Wolseley succeeded in developing a practical hand piece with a comb and reciprocating cutter driven by power transmitted from a stationary engine. The invention greatly increased the profitability of the wool industry.
Ship refrigeration - Credited with the manufacture of the first artificial ice,
Eugene Nicolle and Thomas Sutcliffe Mort developed shipboard refrigeration
that resulted in the export of meat from Australia to Great Britain.
Electric Drill - Arthur James Arnot patented the world's first electric
drill on 20 August 1889 while he was an employee of the Union Electric Company
in Melbourne. He designed it primarily to drill rock and to dig coal.
First powered flight - Perhaps inspired by the boomerang, Lawrence Hargrave
discovered that curved surfaces lift more than flat ones. He subsequently built
the world's first box-kite, hitched four together, added an engine and flew five
freely with other aviation pioneers, including the Wright Brothers, but
unlike the Americans who monopolised their ideas, Hargrave never patented his.
Because it promised public access, Hargrave left all his research to the Munich
gained local support to further develop his ideas and not been so generous in
sharing his ideas with other aviation pioneers, he probably would have been the
first person in the world to achieve sustained and controlled powered flight.
Differential gears - David Shearer of South Australia built a steam
car with a differential inside left rear wheel hub.

which used to take up to 24 hours, Amdel Limited developed an on-the-spot
analysis equipment called the In-Stream Analysis System, for the processing of
copper, zinc, lead and platinum - and the washing of coal. This computerised system
allowed continuous analysis of key metals and meant greater productivity for the
mineral industry worldwide.
1972 Powerboard – The powerboard allows multiple electrical devices to be powered where only a single wall socket is available. It was invented by Frank Bannigan at Kambrook.
1974 Super Sopper – During the Australian summer, no many days of cricket are lost to rain but for Gordon Withnall, even one minute lost was one minute too many. Consequently, he invented the Super Sopper, a giant rolling sponge used to quickly soak up water from sporting grounds so that play could continue.
Plastic injection moulding software -Engineers at Moldflow Pty Ltd
revolutionised the plastic injection process with a new computer aided engineering
software, that simulated the injection moulding process and offered a design strategy
to evaluate, refine and optimise successive simulations. The technique has been
used widely in the automotive, whitegoods, computer, packaging, communications,
aeronautical and photographic industries.
Race-cam - Race Cam was developed by Geoff
Healey, an engineer with Australian Television Network Seven in Sydney. The
tiny lightweight camera is used in sports broadcasts and provides viewers with
spectacular views of events such as motor racing, which are impossible with conventional
Bionic ear - The cochlear implant was invented by Professor Graeme Clark
of the University of Melbourne.
The dual flush toilet - As dunnies have a
celebrated status in Australia, it is apt that Australia has taken a central role
in their evolution. In 1982, the dual flush toilet was responsible for savings
in excess of 32000 litres of water per household a year. Pretty important in the
world's dries inhabited continent.
Wave-piercing catamarans - The high speed catamarans were developed by Phillip
Hercus and Robert Clifford of Incat in Tasmania.
Winged Keel - Ben Lexen designed a winged keel that helped Australia
II end the American's 132 ownership of the America's

shears - The discovery of gene shears was made by CSIRO scientists, Wayne
Gerlach and Jim Haseloff.
1988 Plastic polymer bank notes -Traditionally, paper money has been made out of a kind of cloth that is neither very durable and relatively easy to counterfeit. In 1988, CSIRO scientists led by Dr. David Solomon. Securency Pty Ltd, a joint venture between the Reserve Bank of Australia (RBA) and UCB, brought the note into full production and polymer bank notes. The chief advantages are high counterfeiting resistance and longer circulation lifetimes.

by optical research scientist, Stephen Newman in Queensland.
Supersonic combustion - The University of Queensland demonstrated the world's
first supersonic combustion in an atmospheric flight test at Woomera on July 30,
2002. The craft reached speeds of more than Mach 8, or 8 times the speed of sound.
1992 Spray on skin – Research has found that major scarring of burns victims could be reduced if replacement skin could be provided within 10 days of the burn. Unfortunately, traditional skin culturing techniques took around 21 days to produce enough cells to cover major wounds. Spray on skin is a skin culturing treatment developed by scientist Marie Stoner and plastic surgeon Dr Fiona Wood that reduced the culturing period to five days.
Scramjet - The University of Queensland reported for the first time the development
of a scramjet that achieved more thrust than drag.
Underwater pc - The world's first underwater computer with a five-button hand-held
keypad was developed by Bruce Macdonald at the Australian Institute of
EXELGRAM - The world's most sophisticated optical anti-counterfeiting technology
was developed by the CSIRO.
- Jindalee Radar System - The United States of America spent $11 billion developing
an aeroplane that could not be detected by radar. Scientists at the CSIRO then
concluded that if the plane could not be detected, perhaps the turbulance it makes
passing through air could be. $1.5 million later, the Jindalee Radar system had
transformed the stealth bomber into nothing more than an unusual looking aircraft.
1996 - Hi-Speed Wi-Fi - During the 1990s, around 22 of the world’s computer firms were researching wi-fi as a way of connecting mobile phones and laptops to a wireless network. Wi-fi technology existed, but it was too slow to connect to the Internet. The CSIRO decided it could make use of the Fast Fourier Transform Chip, invented by Australian Dr John O’ Sullivan in the 1980s.
2002 - Hyshot Scramjet Engine - One day, it is theorised that scramjets will allow people to fly from Sydney to London in less than an hour. Presently, no planes fitted with scram jet engines exist, but in 2002, the University of Queensland staged the first successful test of a very high speed air-breathing jet engine and thus showed the scramjets are possible. In June 2007, it was successfully used to boost a test vehicle to hypersonic speeds.
