50 free Australian Geography trivia questions with answers — geography quiz, new questions added Aug 2026.
Australia is a continent, a country and one of the emptiest inhabited places on Earth, and its map rewards anyone who looks past the famous postcard landmarks. Rivers run underground for most of the year, a single lake can be the lowest point on the continent and its largest body of water at once, and a state border can sit on a line of longitude surveyed by camel. These 50 questions cover the rivers and their lengths, the deserts and dune fields, the mountain chains and state high points, the islands and external territories, the tri-state corners, the time-zone quirks, the hottest, coldest and wettest towns, and the roads and railways that cross the lot. Every answer comes with a short explanation and a source. It suits quiz nights, classroom revision and anyone who has driven the long way round and wants to see how much stuck.

Q 01Which road network circumnavigates Australia, joining every mainland state capital?
Highway 1
Highway 1 rings the whole continent and links every mainland state capital, yet it never reaches Canberra, the one mainland capital left off the loop.
Q 02Which South Australian salt basin, full only three times since 1860, holds the nation's lowest natural point?
Lake Eyre
Lake Eyre, officially Kati Thanda–Lake Eyre, lies about 15 m below sea level, so floodwater from as far away as Queensland drains inland to it and evaporates, leaving a salt crust instead of reaching the sea.
Q 03Which Northern Territory park lost its title as Australia's largest national park to a new desert park in 2021?
Kakadu
Kakadu fell to second place in November 2021, when South Australia joined two existing Simpson Desert reserves into one far larger national park after a decade of campaigning by conservationists.
Q 04Which sea do Australians and New Zealanders both call 'the Ditch', as in 'crossing the Ditch'?
Tasman Sea
The Tasman Sea is named for Abel Tasman, who crossed it in 1642 and reached Tasmania and New Zealand, yet sailed right around Australia on that voyage without ever seeing the mainland.
Q 05Which Queensland island beach is famous for fine, pale sand that is almost pure silica?
Whitehaven Beach
Whitehaven Beach, on Whitsunday Island, has sand that came from elsewhere: nearby rocks hold little quartz, so geologists think sea currents carried it north along the Queensland coast millions of years ago.
Q 06Which north Queensland rainforest, billed as the world's oldest, was handed back to its Aboriginal owners in 2021?
Daintree
The Daintree and three neighbouring national parks, about 160,000 hectares in all, were returned to the Eastern Kuku Yalanji people in September 2021, and they now manage them jointly with the Queensland government.
Q 07Which Queensland city, with its business district in Southport, is Australia's most populous non-capital city?
Gold Coast
The Gold Coast was officially the South Coast until 1958: the new name began in the 1950s as a nickname for the area's soaring real-estate prices, and the town then took it as its own.
Q 08Australia is the world's sixth-largest country by area; which country, fifth on the list, is the next size up?
Brazil
Brazil, at about 8.5 million km², sits just above Australia's 7.7 million, yet Australia is also the smallest continental land mass, so the sixth-largest country fills the smallest continent.
Q 09Which of Australia's deserts, straddling the Western Australia–South Australia border, is the largest by area?
Great Victoria Desert
The Great Victoria Desert was named by explorer Ernest Giles, who crossed it in 1875, and in the 1950s Britain tested nuclear weapons inside it, at Maralinga.
Q 10Which vast limestone plateau stretches along the Great Australian Bight between South Australia and Western Australia?
Nullarbor Plain
The Nullarbor Plain takes its name from Latin rather than an Aboriginal language: nullus arbor means 'no tree', apt for a plateau where saltbush and bluebush grow in place of forest.
Q 11Which lighthouse-topped headland in northern New South Wales is the easternmost point of mainland Australia?
Cape Byron
Cape Byron was named by James Cook in 1770 not for the poet but for the poet's grandfather, the navigator John Byron, and a lighthouse built in 1901 now crowns the headland.
Q 12Which point, named by Cook in 1770 for a brother of King George III, is the northernmost tip of mainland Australia?
Cape York
Cape York tips the peninsula where Dutch captain Willem Janszoon made the first recorded European landfall in Australia in 1606; a deadly clash with the Wik people turned him back at a point still called Cape Keerweer, 'Cape Turnaround'.
Q 13Which stretch of the Victorian coast, mostly national park, ends at South Point, the southernmost tip of mainland Australia?
Q 21Which Western Australian headland, the mainland's most south-westerly point, is where Australia says two oceans meet?
Cape Leeuwin
Cape Leeuwin is where Australian charts divide the Indian Ocean from the Southern Ocean, but most other countries start the Southern Ocean at 60°S, so on their maps the cape faces the Indian Ocean alone.
Q 22Which Western Australian outback town set a record of 160 consecutive days at or above 37.8 °C, starting in October 1923?
Marble Bar
Marble Bar's streak ran from 31 October 1923 to 7 April 1924, and the town owes its name to a mistake: the colourful bar of rock across the Coongan River is jasper, not marble.
Q 23Which snow-resort village in Kosciuszko National Park recorded Australia's lowest temperature, −23.0 °C, in June 1994?
Wilsons Promontory
Wilsons Promontory, 'the Prom' to Victorians, was closed to the public during the Second World War while the army trained commandos there, and a memorial in the park honours those who died.
Q 14Which of Australia's islands, off South Australia's Fleurieu Peninsula, ranks third in size behind Tasmania and Melville Island?
Kangaroo Island
Kangaroo Island was named in 1802 by a British navigator whose crew, after four months almost without fresh food, feasted on its kangaroos; he chose the name, he wrote, 'in gratitude for so seasonable a supply'.
Q 15Which sea stack off Lord Howe Island, the tallest in the world, shelters the last wild population of a giant stick insect?
Ball's Pyramid
Ball's Pyramid hid the Lord Howe Island stick insect, which ship rats wiped out on the main island and which was presumed extinct by 1920, until a 2001 survey found a tiny colony clinging on there.
Q 16Which Australian external territory, far closer to Java than to the mainland, is famous for its annual red crab migration?
Christmas Island
Christmas Island's red crabs leave the forest by the million with the first wet-season rain and march to the sea to breed, so the island has built crab bridges over its roads to let them pass.
Q 17Which remote sub-Antarctic territory, dominated by the glacier-clad Big Ben, holds Australia's only active volcanoes?
Heard Island
Heard Island's Big Ben volcano peaks at 2,745 m Mawson Peak, so the highest mountain on Australian soil outside Antarctica is not Kosciuszko but an ice-covered volcano in the far southern Indian Ocean.
Q 18Which river loops through the Australian Capital Territory before crossing New South Wales to join the country's longest river?
Murrumbidgee
The Murrumbidgee is dammed at Burrinjuck to supply the Murrumbidgee Irrigation Area, so its water turns inland plains into productive irrigated farmland.
Q 19Which river, flowing through Perth to the sea at Fremantle, did Dutch captain Willem de Vlamingh name in 1697?
Swan River
The Swan River got its name from the many black swans de Vlamingh's men found on it, and he rowed some ten miles upstream before sailing on north.
Q 20Which body of water's southern shore, near Burketown, is the surest place to see the Morning Glory cloud each spring?
Gulf of Carpentaria
The Gulf of Carpentaria's Morning Glory is a roll cloud that can stretch 1,000 km, and glider pilots travel to Burketown each spring to switch off their engines and surf its updraughts.
Charlotte Pass
Charlotte Pass is cut off by snow every winter, so guests finish the trip by oversnow vehicle from Perisher Valley; it is Australia's highest ski resort and the village closest to Mount Kosciuszko.
Q 24Which north Queensland sugar town put up a 7.9 m 'Golden Gumboot' to back its claim to be Australia's wettest?
Tully
Tully's boot stands 7.9 m tall because that much rain, 7,898 mm, fell on the town in 1950, though rival Babinda has the higher long-term average and disputes the title.
Q 25Which mining city in far-western New South Wales keeps South Australian time, half an hour behind Sydney?
Broken Hill
Broken Hill keeps Central Standard Time because, when the colonies adopted standard time in the 1890s, its only railway ran to Adelaide rather than Sydney; the surrounding Yancowinna County follows suit.
Q 26Which outback corner post marks the point where Queensland, South Australia and the Northern Territory meet?
Poeppel Corner
Poeppel Corner is named for the surveyor Poeppel, whose post first stood out in a salt lake; a later survey found an error in his chain measurements and moved it to the shore.
Q 27Which bay on the New South Wales coast did the Commonwealth acquire in 1915 so that landlocked Canberra could have a seaport?
Jervis Bay
Jervis Bay was acquired for a port, yet in 1995 the national park on that federal land was handed to the Wreck Bay Aboriginal Community, which renamed it Booderee, meaning 'bay of plenty'.
Q 28Which city at the Hunter River's mouth was home to the world's largest coal port as of 2022?
Newcastle
Newcastle sent out its first commercial coal cargo in 1799, making it Australia's first export port, and in 2022 the world's largest coal port announced it would run entirely on renewable power.
Q 29Which highway between Darwin and Port Augusta is named for the explorer who crossed the continent from south to north in 1861–62?
Stuart Highway
The Stuart Highway honours John McDouall Stuart, who reached the north coast in July 1862 so ill with scurvy and so nearly blind that he was carried much of the way home on a stretcher slung between two horses.
Q 30Which 1917 line between Port Augusta and Kalgoorlie includes the world's longest dead-straight stretch of railway?
Trans-Australian Railway
The Trans-Australian Railway was a price of federation: Western Australia made a rail link to the east a condition of joining the Commonwealth, and crews laid it from both ends until they met in 1917.
