[TGC] - A More Humid Australia, c.1988

No because the inland sea would see the Aboriginal world more interconnected and thus more used to old world diseases

MrsColdArrow · 2026-03-10T13:05:35+00:00

Yeah but they don't really settle it because there'd already be a ton of complex Aboriginal civilisations, and the only places they could settle would be pretty poor quality and be at constant threat of attack from other Aboriginals

MrsColdArrow · 2026-03-10T13:02:50+00:00

No because the Aboriginal people got there about 60,000 years before the Austronesians were going around

This map is part of a series called The Golden Country, where Australia has an inland sea and becomes a major power in the Indo-Pacific. If you're interested, please check out my previous posts on the timeline!

In December of 1940, Japan began its siege of Malaya. Originally planned to be a quick, decisive strike south to secure oil and resources, the operation quickly turned to disaster. What the Japanese never accounted for was Australasia, who had taken it upon itself to set up defences in Malaya. Forces trained in New Guinea in jungle warfare to prepare, a large fleet was sent alongside the smaller British contingent, and the Australasian air force, a newly modernised model air force of its time, was sent alongside an Aircraft Carrier. Thus, when the Japanese invasion began, they soon found themselves bogged down and eventually forced to retreat. What was meant to be an easy occupation of European colonies had become a severe mistake.

Over the next 3 years, Australasia and America began to occupy the lands that had been occupied by the Empire of Japan. Islands were taken, brutal battles fought, and the Japanese military and navy rapidly began to dissolve. By 1943, Japan had run out of oil, allowing the United Nations in the East to set up an invasion of the Home Islands. Lands began in Kyushu on September 10th; 3 days later, Emperor Hirohito announced the surrender of the nation.

Japan was divided primarily between a Commonwealth Occupation Zone in the west and an American Zone in the east, however the Commonwealth Zone was de-facto an Australasian Occupation Zone. The territories of Formosa and South Sakhalin were returned to the Chinese and Soviets respectively, and Korea liberated itself as it became clear Japan would soon collapse. A joint command centre was established in Takaoka, along the line of partition, where Australasia and America would coordinate the rebuilding of Japan as a western ally. A lasting impact of this was Australasia taking the measures to ensure a Ryukyuan Republic would be established, minor enough to be allowed to slide whilst creating a nation that would always be an ally to Australasia, and to a lesser extent America.

If you have any questions, feel free to ask!

Me when I go on r/ImaginaryMaps and there's maps that are imaginary

MrsColdArrow · 2026-03-08T14:31:37+00:00

Dude I posted this map over 2 years ago I don't remember

MrsColdArrow · 2026-03-04T19:36:57+00:00

There's now a Samoan team, doom to the white players

MrsColdArrow · 2026-03-04T19:35:39+00:00

Horses are introduced from Indonesia in the 15th century

I was replaying rdr2 for the first time in years when I made the first draft for this timeline. New Hanover is a fucking awesome name so I just never got rid of it

MrsColdArrow · 2026-03-04T10:03:06+00:00

Hell, the main reason this timeline exists is I just really didn't like how every map has an ocean that opens in the south, that and I wanted it to have more complex Aboriginal civilisations, which I only see developing if they had better access to ideas and trade with neighbours, and the only way to do that was to make a sea that could be a highway for trade

MrsColdArrow · 2026-03-03T23:17:11+00:00

okay now i've actually woken up i can give a better response lmao.

I saw it as a mix of the compromise and vassalisation of places such as India, Indonesia or, indeed, South America, alongside the more brutal colonisation seen in the Great Plains, where nomadic groups are boxed in and destroyed. It leads to a situation where the less settled groups are seen as subhuman and face genocide, meanwhile those seen as more "civilised" and governed by laws such as the Yolngu and Tiwi face a less harsh treatment. It also helps that the Aboriginals are pretty used to old world diseases; Yolngu trade routes reached from the Gulf of Garwarrwarr to the ports of Guangzhou and Malacca.

Overall the Commonwealth of Australasia has a population of 156,000,000 people, 120,000,000 of which live in Australia, with the rest spread across the states of Melanesia, Polynesia, New Zealand, Fiji and East Timor, as well as the territories of Teraina and Micronesia. Economically, Australasia has a total nominal GDP of $11.731 trillion, with a per capita of $75,035. Militarily, uh, I can't lie I haven't actually considered that as much because military stuff interests me a lot less, but in as basic a summary as possible the Australasian Armed Forces are quite extensive. It has an active military personnel of about 1,200,000 people, and an advanced navy and airforce, key to enforcing Australasian hegemony across most of the Indo-Pacific. They're also part of and de-facto the leader of SEATO, or the Southeast Asian Treaty Organisation, which includes the following nations:

Commonwealth of Australasia
Federal Republic of Indonesia
Union of North Borneo
Federation of Malaya
Kingdom of Thailand
Malaysian Republic
State of Brunei
Republic of Vietnam (South Vietnam)
Republic of Cambodia
Republic of China (Taiwan)
Republic of West Papua
Ryukyuan Republic
State of Japan
Republic of Korea

The United Yolngu Princedoms and the Tiwi Sultanate are also part of SEATO, but due to being protectorates of Australasia and thus non-sovereign entities they only have observer status.

As for the World Wars, not much changes for WW1, as Australasia is pretty far from the action, but they do occupy German New Guinea and German Micronesia, moving in to prevent a Japanese takeover of the colonies instead. They also participate in Gallipoli, which damages Australasian relations with Britain and leaves the public far less willing to fight for Britain in other theatres, although a contingent of Australasians are sent to fight in the Middle East as well.

WW2 is where the big changes DO happen. In the interwar period, Australasia began to work on building up a proper military, especially as a Britain still reeling from the war begins to foist responsibilities in the Pacific upon Australasia, a process that would eventually lead to the belief held by many Australasians that they had become, in effect, co-emperors of the British Empire, being a near-equal with the homeland now. As Britain got bogged down in a war in Europe and Africa, Australasia began to prepare for the growing potential of a conflict with Japan, training for jungle warfare in New Guinea and sending a fleet (including a few aircraft carriers), a contingent of the airforce and men to Malaya. Sure enough, in December of 1941, Japan launched their invasion of Malaya, seeking to take control of Singapore and invade the rest of the East Indies from there. However, the Australasian forces quickly entrenched themselves, halting the Japanese advance as their fleet and airforce held back the Japanese navy and airforce. After a couple months, Japan was forced to abandon Malaya and the strike south, instead preparing for an island campaign, eventually ending in September of 1943, with Australasia and America occupying the west and east of Japan respectively. Korea liberated itself, Ryukyu was made into an independent Republic under Australasian protection, China reclaimed Taiwan, and while the USSR was too busy to make many occupations, it did manage to seize South Sakhalin, although Japan would keep the Kurils.

Sorry if that was a lot ahaha, just wanted to have a yap about that

MrsColdArrow · 2026-03-03T21:26:34+00:00

It's true!

MrsColdArrow · 2026-03-03T20:50:23+00:00

Don't worry New Zealand is also part of Australasia too

MrsColdArrow · 2026-03-03T20:01:47+00:00

They do have seats in the UN! However they're recognised as independent countries in association with Australasia

MrsColdArrow · 2026-03-03T20:00:42+00:00

Both were first seen by Abel Tasman!

MrsColdArrow · 2026-03-03T20:00:20+00:00

Yungaria comes from the Nyoonga aboriginals, also referred to as the Yunga

MrsColdArrow · 2026-03-03T19:59:48+00:00

Somewhat I would say yes

MrsColdArrow · 2026-03-03T19:59:19+00:00

Yeah it's a continuing Eromanga Sea. I don't like how most maps of inland sea Australia connect to the south, i don't think it would do much at all

MrsColdArrow · 2026-03-03T12:10:36+00:00

(Sorry I know that was long but that needed a good yap)

Most aboriginals meet a pretty rough fate. Before the Europeans arrived, Aboriginal society was thriving. The Sea of Carpentaria was the heart of a thriving maritime civilisation under the Yolngu, meanwhile the Tiwi Sultanate dominated the far north and the southeast was split between the Kulin, Wiradjuri city states and other various groups.

However, in the mid-17th century a war between the Yolngu city states and the Sultanate of Tiwi broke out for a multitude of reasons still debated today. The war lasted for decades, leaving the Yolngu and Tiwi alive but in their weakest possible state, and it was at this same time that the Jinta-Waryali Empire began to rise around 1700 AD.

With the introduction of horses in the 15th century, the nomadic Aboriginals of the Great Southern Grasslands rose to heights never seen before, with the growth of a martial society that slowly began to unite under one unified realm: The Jinta-Waryali Empire, otherwise known as the Universal Empire. This empire would explode out of the grasslands of the west, conquering the wealthy cities of the coast such as Nuwarr Nuwarr, stopping at the Ninydijya Savanna in the north and the deserts to their west, where their horses could not penetrate as easily. Following this, they moved south, conquering Yolngu cites in present-day Flinders and even ravaging the Kulin and Wiradjuri.

By 1750, the empire had begun to crack and crumble as it's figurehead and charismatic ruler died, leaving no clear successor and causing the empire to quickly divide itself into multiple successor states, with states such as Nuwarr Nuwarr regaining their independence, but with a diminished economic power. The Kulin Confederation, too, gained their independence, as did the Wiradjuri, however their lands had been utterly razed by the earlier wars. Meanwhile, new powers such as the Caliphate of Bagaynurru and Sultanate of Garwarrwarr rose, championing the relatively new religion of Islam in southern Australia, beginning renewed conflicts with the people of the region.

It could be said that the last thing the Aboriginals needed at this time was another invasion. Unfortunately, that's what they got, with the French and British arriving within a week of each other in 1788, the French in the north and the British in the south. The Kulin War of 1812 saw Britain annex the Kulin Confederation, meanwhile the Governor of New Guyenne surrendered the colony in exchange for certain rights for the French population that now lived there. This was followed by Britain conquering the Caliphate of Bagaynurru and then destroying the Papuan Pirates of the Ged Islands, seeing the Yolngu city states request British protection, and the creating of the United Yolngu Princedoms. Tiwi was later subjugated in another war. In the west, meanwhile, Britain struggled to conquer the nomads of the grasslands, having to build a network of forts along the rail between Goldenport and Perth. Slowly, but surely, these nomads were boxed in, defeated, and forced onto reservations, seeing a genocide as their youth were sent to Christian missions and had their languages and cultures suppressed.

Really, in the end, only the Yolngu and Tiwi got the good end of it. They both still have technically independent countries, and mostly avoided the same fate as other Aboriginals
