Australia has over 750 species of reptiles, the most in the world
Australia is a haven for reptiles, boasting over 750 species—a number that has only increased since 1993. This diverse range of reptilian species scattered across the country's sprawling and varied landscapes cements Australia's status as one of the world's major reptile centres.
The continent's reptiles range from the awe-inspiring saltwater crocodiles of the north to the tiny geckos that climb city walls. Some of the most recognisable reptiles in Australia include the Blue-tongue Skink, which has adapted to urban environments and is often found in gardens, and the Red-bellied Black Snake, one of the most well-known serpents on the continent.
Australia's isolation has allowed unique species to evolve, with reptiles adapting to a wide range of environments, from arid deserts to lush tropical rainforests. This has led to the development of extraordinary survival mechanisms, such as the water-harvesting abilities of the Thorny Devil and the selective basking behaviours of large monitors.
The discovery of new species continues to this day, with Queensland Museum's curator of reptiles and amphibians, Patrick Couper, having helped name 52 new species in the past 25 years, with more on the way. The biodiversity of Australia's reptiles is a fascinating aspect of the country's natural heritage and a testament to the adaptability and resilience of these ancient creatures.
However, it is important to note that some species, like the Manning River Turtle, face mounting conservation challenges due to their restricted habitats and vulnerability to environmental changes.

It's home to the world's oldest fossil, dating back 3.4 billion years
Australia is home to the world's oldest fossils, dating back 3.4 billion years. This discovery was made by scientists from the University of New South Wales (UNSW) in 2017. The fossils were found in Western Australia, in the Pilbara region, which is known for its rich fossil record.
The fossils are of bacteria that lived in oceans without oxygen. They were grouped in clusters and chains, similar to those formed by modern bacteria. The cell walls of these bacteria were preserved, and they were found to have a similar size and structure to previously discovered microfossils of bacteria that lived two billion years ago. The fossils were embedded in a sandstone layer from a shallow-water beach, which is now known to be one of the Earth's oldest preserved shorelines.
The discovery provides valuable insights into the nature of early life on Earth. The presence of tiny crystals of pyrite, or "fool's gold", near the cell walls suggests that the bacteria drew energy from sulphur. This is further supported by chemical analyses of the minerals near the cells. The findings indicate that life may have originated in freshwater hot springs on land, rather than in the ocean as previously thought.
This discovery has significant implications for our understanding of the development of life on our planet and beyond. It also highlights the importance of the Pilbara region as a key site for studying early life on Earth and developing exploration strategies for potential life on other planets, such as Mars.

The country has more venomous snakes than non-venomous ones
Australia is known for its dangerous snakes, and it has many. The country has over 170 species of land snakes, with some equipped with venom more toxic than any other snakes in the world. Deadly serpents account for 65% of Australia's snake population, while only about 15% of the world's snakes are venomous.
The Mulga, for example, is the heaviest venomous snake in Australia and has the largest-recorded venom output of any snake in the world. Its bite delivers 150mg of venom in one bite, while the average tiger snake produces only 10-40mg. The temperament of the Mulga seems to vary with locality. Southern Mulgas are reported to be shy and quiet, while Northern specimens are much more agitated if disturbed.
The Small-eyed Snake, while petite at about 50cm long, also has venom that can pack a punch and shouldn't be underestimated. Little is known about its toxicity, but bites have caused illnesses in snake handlers and there has been one known fatality. The venom contains a long-acting myotoxin that continues to attack muscle tissue, including the heart muscle, for days after the bite.
While snakes in Australia are indeed venomous, bites are quite rare, and since the development of antivenom, fatalities have been low—between four to six deaths per year. According to Associate Professor Bryan Fry, a herpetologist and venom expert at the University of Queensland, "snake bites are very, very rare [in Australia] and often the fault of the person being bitten. Most bites occur when people are trying to kill a snake or show off."

The name 'Australia' comes from the Latin word 'australis', meaning 'southern'
The name Australia is derived from the Latin word 'australis', meaning 'southern'. The name was popularised by the explorer Matthew Flinders, who pushed for its formal adoption as early as 1804. In 1814, Flinders published a book titled 'A Voyage to Terra Australis', detailing his journey around Australia. In the introduction, he wrote:
> "Had I permitted myself any innovation on the original term, it would have been to convert it to AUSTRALIA; as being more agreeable to the ear, and as an assimilation to the names of the other great portions of the earth."
The name Australia replaced 'New Holland', an English translation of the Dutch name first given by Abel Tasman in 1643. The earliest recorded use of the word Australia in English was in 1625 in 'A Note of Australia del Espíritu Santo', written by Sir Richard Hakluyt and published by Samuel Purchas. However, this was a variation of the original Spanish name 'Austrialia del Espiritu Santo' (Southern Austrian Land of the Holy Spirit), coined by navigator Pedro Fernandes de Queirós in 1606 for the largest island of Vanuatu.

It's the only continent without an active volcano
Australia is a country full of surprises and unique characteristics. From its diverse wildlife and flora to its cultural significance, Australia never ceases to amaze. One fascinating fact about this continent is that it is the only one without an active volcano. While Australia is home to nearly 150 volcanoes, none of them have erupted in approximately 4,000 to 5,000 years, making them dormant or extinct.
The absence of active volcanoes in Australia can be attributed to its geographical location relative to tectonic plates. Volcanoes typically form at tectonic plate boundaries, where two plates meet and interact. However, Australia sits comfortably in the middle of the Indo-Australian Plate, isolated from any significant geological faults that could trigger volcanic eruptions. This tectonic plate stability also contributes to Australia's lack of earthquakes and continental drift.
Although the mainland of Australia lacks active volcanoes, its external territories tell a different story. Heard Island and McDonald Islands, located around 2,485 miles southwest of Perth, are home to the continent's only active volcanoes. These outlying volcanoes provide a fascinating contrast to the otherwise volcanically calm mainland.
The lack of active volcanoes in Australia doesn't diminish its geological wonders. Uluru, for example, is one of Australia's most iconic landmarks and holds cultural and natural significance, earning it a double listing as a UNESCO World Heritage Site. Additionally, Mount Augustus in Western Australia claims the title of the world's largest rock, surpassing the famous Uluru in size.
Australia's diverse landscapes offer something for everyone. From the snowy slopes of the Australian Alps to the sunny beaches of Queensland, Australia attracts skiers, surfers, and nature enthusiasts alike. The country's vast deserts and vibrant cities, such as Sydney, Melbourne, and Perth, contribute to its allure. So, while Australia may not have active volcanoes, its geological wonders and natural beauty continue to captivate and enchant visitors from all over the globe.
