1. It's the most "liveable" place on Earth
According to The Economist Intelligence Unit, it has four of the 10 most "liveable" cities in the world, based on factors such as stability, healthcare, culture, environment, education and infrastructure. They are Melbourne (1), Adelaide (5), Sydney (6) and Perth (7). London languishes in 53rd place...
2. With some of the world's most surreal landscapes
Like Tasmania's Bay of Fires:
And Wave Rock in Western Australia:
3. Which you'll have pretty much to yourself
Australia has a population density of just 3.1 people per square kilometre, making it less crowded than all but six other destinations (Greenland, the Falkland Islands, Mongolia, Western Sahara, Namibia and French Guiana).
4. There's fascinating indigenous culture
Aboriginal artistic, musical and storytelling traditions date back thousands of years. Among the best places to immerse yourself in them is the Kimberley region in north-western Australia, which has one of the highest concentrations of indigenous rock art in the country, and the Kakadu National Park near Darwin, which is home to as many as 5,000 sites.
5. Some brilliant place names
Who can't but smile while exploring places like the Bungle Bungle ranges, Humpybong and Yorkeys Knob?
6. And one of the world's greatest road trips
The Great Ocean Road from Torquay to Allansford, constructed in the Twenties by returned Australian servicemen, has its fair share of jaw-dropping scenery, from sheer ocean cliffs to untouched surfer beaches. But it also traverses one of the most civilised parts of rural Australia – a region rich in farm-fresh produce, seafood and cool-climate wines. See our guide to driving it here.
7. It's got wildlife you won't find (almost) anywhere else on Earth
From kangaroos, koalas, wallabies and wombats to the adorable quokka.
8. And if you're excited by deadly creatures, it can't be beaten
Box jellyfish, saltwater crocs, sharks, funnel web spiders and pretty much all of the world's deadliest snakes? Check.
9. It has (arguably) the world's most beautiful harbour
With its most famous opera house.
10. The world's largest coral reef system
The Great Barrier Reef is composed of more than 2,900 individual reefs and 900 islands stretching for 1,400 miles. Then there's Australia's "other" reef - incredible Ningaloo.
11. And a giant red rock that's like nothing else in the world
Uluru is a truly remarkable sight and so big it takes around three hours to complete the 10km loop of its base.
12. The wine is worth the airfare alone
And the welcome from its winemakers can't be topped. Robert Joseph explains: "Where French vignerons generally presume that anyone crossing their threshold is a wine enthusiast, the Aussies have learned that they are in the entertainment business. Most normal mortals are fascinated, or at least mildly intrigued, by their first encounter with rows of vines, barrels, wine presses and fermentation tanks, but by the time they see their third set of oak casks, the interest tends to wane. So the Aussies often propose rather more than a tour and a tasting. There are art galleries, gardens and golf courses; cafés and cordon bleu restaurants; cottages and luxury suites. Wineries that don't offer food sometimes provide picnic areas and barbecue facilities for you to sort out your own lunches and some even have swings and slides for those too young to taste."
13. Its culinary scene is thriving too
Australia's restaurants are better than ever - Terry Durack's feature outlines how unique produce and chefs unburdened by culinary traditions are creating novel, dynamic and delicious dishes.
In fact the culinary scene there is so inspiring that René Redzepi has taken Noma to Sydney and Heston Blumenthal moved The Fat Duck there.
14. It has one of the world's greatest rail journeys
"Australia’s red centre is one of the most spectacular wildernesses in the world, and the Ghan is unquestionably the most comfortable way to see it," says Anthony Lambert. "The train runs through the heart of the country: 2,979km (1,861 miles) between the south coast at Adelaide and the north coast at Darwin, taking two nights and three days."
15. And one of the most impressive train stations
Flinders Street Station is the busiest in Melbourne, with more than 100,000 commuters passing through each day. It's also photogenic, especially when the city's trams pass by. Melbourne is also one of the world's coolest cities - "a moody, complex, deep-thinking metropolis more akin to Berlin than Brisbane - a place obsessed with art, food and coffee, packed with switched-on galleries, architectural flourishes, independent bookshops, cafés, and iconic music venues," according to our resident expert.
16. Expect sun. Lots of it
And Christmas by the seaside.
17. It's got more city beaches than you can shake a windbreak at
Whichever city you choose for an Australian holiday, there will be a buzzing metropolitan beach or a secluded cove within easy reach.
18. And some incredible ones in the sticks, too
Like Whitehaven, in the Whitsundays:
19. There no pretentiousness
It's an informal place - and Aussies have a robust sense of humour.
20. Its national airline is the world's safest
Qantas, that is. And if you travel with them in first or business class you can use virtual-reality headsets to make the journey more interesting.
21. They've got the "Big Things"
Something of a roadside cult phenomenon in Australia are the many, varied "Big Things" that have sprouted up, mostly in rural towns, including the Big Merino in Goulbourn, New South Wales:
And The Big Axe in Kew, Melbourne:
22. A cruise around the Kimberley region might just change your life
We rated is among our 21 holidays to make you a better person and the 20 best destinations to visit in 2016. "Here was tectonic chaos laid bare: great lava-like cliffs of rock, towering rock escarpments and a honeycomb strata with holes so big you could put your fists in. It was a thousand geography lessons rolled into one," explains Teresa Machan.
23. It's home to two of the greatest hotels in the world
Qualia, in the Whitsundays:
And Southern Ocean Lodge on Kangaroo Island:
24. Its landscapes are unbelievably diverse
Red dirt deserts, tropical beaches, snow-capped mountains and temperate rainforest can all be found here.
25. It's heaven for surfers
Particularly if 18-metre waves are your thing.
26. And hikers
Try the Grampians (pictured below) in Victoria or the Blue Mountains of New South Wales.
27. And finally... it gave us The Castle
Not to mention Campese, Bradman, Richie Benaud, Errol Flynn and AC/DC.
