Not everyone agrees, but it's got a patent to prove it.
The agency has sued companies using the technology without a license -- its 20-year patent expires next month.
It's not the first time the CSIRO has claimed a place in history.
In July 1969, its 64-meter (209-foot) radio telescope in Parkes received television signals that allowed 600 million people to watch Neil Armstrong's moonwalk live.
The observatory, affectionately known as "The Dish," is open to visitors in the NSW country town that's also home to an annual Elvis festival.
5. The big island is surrounded by more than 8,000 smaller islands
Some people say Australia is the largest island on earth, while others call it a continent because it has its own tectonic plate.
Whichever way you look at it, the island continent is fringed by thousands of smaller islands -- 8,222 to be precise.
It's got an island state (Tasmania), the world's largest sand island (Fraser) and an Antarctic island (Macquarie).
Many islands are named after animals, including Kangaroo Island off the South Australian coast, Lizard Island in the Great Barrier Reef and Cockatoo Island in Sydney Harbor.
6. It has a "Greek city"
Melbourne has the largest Greek-speaking population in the world, after Athens and Thessaloniki.
In fact, more than 200 languages and dialects are spoken in Australia.
That's because more than 25% of Australians were born in another country, making Oz a melting pot of multiculturalism.
Melbourne's vibrant Greek quarter around Lonsdale Street is home to Stalactites restaurant, a city institution open 24/7, and the annual Antipodes Festival, which features Zorba dancing and lots of souvlaki.
7. The country's one and only military coup was over rum
Aussies have a desperate love affair with beer, but in the late 18th century, rum was a popular form of payment in the fledgling colony of Sydney.
That is until 1808, when Governor William Bligh decided to stop the practice.
The edict didn't go down well with ringleaders of the rum trade, the New South Wales Corps. The regiment deposed Bligh in a military coup later known as the Rum Rebellion.
The city's boozy past can be soaked up via a four-hour walking tour of the historic Rocks area with Sydney Urban Adventures ($137 per person).
8. Only 20 of its snakes will kill you
Most Aussies are proud of their killer wildlife.
The country has 140 snake species and more of the venomous variety than any other continent.
In fact, 20 of the world's 25 deadliest snakes are found slithering here, including the entire top 10.
They're not all nasty. Snakes are naturally shy and would rather not come across humans.
