Australia historical timeline

History

Australia is the only country that is also a continent, and its history reads as two timescales that barely touch: a human occupation running back tens of thousands of years, and a federal state younger than the Sydney Harbour foreshore it governs. What a traveller meets is the seam between them -- a country whose states behave like the separate colonies they were, whose capital was built from nothing because none of those states would accept another's city, and whose most famous rock is managed under a lease from its traditional owners.

Chronology

1788 The First Fleet arrives at Sydney Cove in January and establishes a penal colony. The site chosen for a prison harbour became the country's largest city, which is why Sydney's oldest streets run down to the water at The Rocks rather than out from a square.
1851 The gold rushes begin, and the total population increases nearly fourfold from 430,000 in 1851 to 1.7 million in 1871. The goldfields towns of Victoria and, later, Western Australia are what that money built -- ornate public buildings in places with a few thousand residents today -- and the period is when Australia first became a multicultural society.
1901 The six self-governing colonies -- New South Wales, Queensland, South Australia, Tasmania, Victoria and Western Australia -- become states of the Commonwealth of Australia on 1 January. They kept the systems of government they had built separately, which is why speed limits, alcohol rules and school holidays still differ by state and why the state borders on the map are real administrative lines.
1913 Canberra is proclaimed the national capital, on territory transferred from New South Wales on 1 January 1911 under Section 125 of the Constitution. The capital exists because Sydney and Melbourne could not concede to each other, and it is why the seat of government is an inland planned city rather than either of the places visitors actually arrive in.
1915 The Gallipoli campaign runs from 19 February 1915 to 9 January 1916, and is considered by some the beginning of Australian and New Zealand national consciousness. The anniversary of the landings, 25 April, is Anzac Day -- the most significant commemoration of military casualties and veterans in both countries, ahead of Remembrance Day -- and a visitor in Australia that morning will find the country shut and every town at a dawn service.
1932 The Sydney Harbour Bridge is formally opened on Saturday 19 March. It joined the central business district to the North Shore and fixed the shape of the harbour a visitor photographs; the nickname, the Coathanger, comes from its arch.
1942 Japanese aircraft bomb Darwin on 19 February, the first attack on the Australian mainland, and the Northern Territory and northern Western Australia are bombed roughly 100 times between 4 March 1942 and 12 November 1943. It is why Darwin has military heritage sites, wartime airstrips and oil tunnels open to visitors, and why the north experienced the Second World War quite differently from the southern cities.
1973 The Sydney Opera House is formally opened by Queen Elizabeth II on 20 October, designed by Jørn Utzon and completed by an Australian team under Peter Hall. Construction ran in four stages from 1957; the outer shells, based on the image of whales breaching, took from 1963 to 1967 alone.
1974 Cyclone Tracy destroys more than 70 per cent of Darwin's buildings, including 80 per cent of its houses, over Christmas; some 30,000 people are left homeless and most of the population is evacuated by air and road. The city was rebuilt to cyclone code, which is why Darwin has almost no pre-1975 fabric and reads as a modern tropical city rather than a historic one.
1975 The Great Barrier Reef Marine Park Act creates the Great Barrier Reef Marine Park Authority and defines what is prohibited on the reef. Every permit, zoning rule and operator licence a visitor encounters on the reef descends from this act, which is why reef tourism is regulated rather than simply available.
1985 Ownership of Uluru is returned to the Aṉangu on 26 October, on condition of a 99-year lease back to the national parks agency and joint management. Joint management is what a visitor now encounters at the park: the rules, the closed areas and the photography restrictions are the traditional owners' decisions, administered by the Commonwealth.
1992 The High Court decides Mabo on 3 June, rejecting the doctrine that Australia was terra nullius and holding that rights arising under native title are recognised in the common law. It is the legal ground beneath every Welcome to Country, permit system and Aboriginal-owned tour a traveller now meets.
1993 The Native Title Act gives that decision a statutory framework. Access to substantial areas of the north and the centre now runs through Aboriginal land councils, which is why parts of Arnhem Land and the Kimberley require a permit rather than a booking.
2019 Climbing Uluru is banned from 26 October, thirty-four years to the day after the handback, and the chains that aided climbers are removed. The rock is walked around rather than up, and the base walk is now the visit.

What survived, and what did not

Australia's built heritage is thin and recent by the standards of the places most of its visitors come from, and the losses were mostly deliberate: the gold-rush and post-war booms rebuilt the centres of Sydney, Melbourne and Brisbane more than once. What survived tended to survive through poverty or remoteness -- the sandstone terraces of inner Sydney, the goldfields towns of Victoria and Western Australia that stopped growing when the seam ran out, the Tasmanian convict sites that were too grim to repurpose and too solid to demolish.

The older heritage is not built at all, and its protection is a much more recent achievement. Rock art, ceremonial sites and living cultural landscapes are protected now through a combination of World Heritage listing, national park management and the native title framework that followed Mabo. For a traveller this has a practical edge: the oldest and most significant things in the country are frequently the ones with the most conditions attached to seeing them, and those conditions are set by the people whose sites they are.
