Timeline of Australian inventions

Australian inventions span from ancient Aboriginal technologies to cutting-edge modern innovations, listed here by their introduction date. The nation’s geography and isolation are often cited by the government as a source of its inventiveness, with island-continent status driving advances in maritime and aeronautical fields—such as powered flight, the black box flight recorder, the inflatable escape slide, the surf ski, and the wave-piercing catamaran winged keel.

Agriculture and mining, dominant since early European settlement, yielded inventions like the grain stripper, stump-jump plough, mechanical sheep shears, Dethridge water wheel, froth flotation ore separation, instream ore analysis, and the buffalo fly trap. Weapons systems include the woomera, tank, and underwater torpedo. Medical technology has seen ultrasound, the bionic ear, first plastic spectacle lenses, electronic pacemaker, multi-focal contact lens, spray-on artificial skin, and anti-flu medication.

Household items include Vegemite and the process for permanently creased fabric. Many inventors receive little credit, often overshadowed by more famous Europeans. David Unaipon, an Aboriginal man called “Australia’s Leonardo,” contributed a sheep-shearing tool, centrifugal motor, multi-radial wheel, and mechanical propulsion device; he appears on the $50 note. The CSIRO, a government-funded institution, supports scientists and engineers featured in this list, leading research in fields like using insects for weed control, sustainable crops, and transport improvements.

Aboriginal technology – before 1788

Didgeridoo – A wind instrument from northern Australia, sometimes called a “drone pipe,” classified as an aerophone. Traditionally made by selecting a eucalyptus branch, burying it near a termite mound so termites hollow it out, producing a long, hollow piece of wood. Woomera – A spear thrower that adds thrust to a spear during throwing. 1843 – Grain stripper – John Wrathall Bull invented and John Ridley manufactured the world’s first mechanised grain stripper in South Australia.

Colonial era – 19th century

It used a comb to lift crop ears, with revolving beaters depositing grain into a bin. 1856 – Refrigerator – James Harrison produced the world’s first practical ice-making machine and refrigerator, using vapour compression.

1856 – Secret Ballot – Henry Chapman invented the secret ballot, first used in the Victorian election on 23 September 1856. Voters were marked off on the electoral roll, given a printed ballot, and retired to separate compartments to mark it secretly before depositing it in a locked box watched by officials and scrutineers. 1858 – Australian rules football – Tom Wills wrote a letter published in Bell’s Life in Victoria & Sporting Chronicle on 10 July 1858, calling for a “foot-ball club” to keep cricketers fit in winter.

An experimental match was played at Richmond Paddock (now Yarra Park) near the Melbourne Cricket Ground on 31 July 1858. The Melbourne Football Club rules of 1859, drawn up at the Parade Hotel on 17 May by Wills, W. J. Hammersley, J. B. Thompson, and Thomas Smith, are the oldest surviving set of laws for Australian football.

The game wasn’t immediately adopted; rules had to be agreed before each match. By 1866, several clubs played by an updated version of Melbourne’s rules. 1859 – Photolithography – Developed by John Walter Osborne at the Victorian government’s Crown Lands Office.

During a land boom, the office struggled to produce maps and documents. Master copies were saved as glass slides about 6 inches square, replacing surveyor’s originals or stone originals. 1868 – Granny Smith Apple – Propagated by Maria Ann Smith in Eastwood, New South Wales. 1874 – Underwater torpedo – Invented by Louis Brennan, with two propellers rotated by wires attached to the torpedo.
