Common contraction of Western Australia, an Australian state. (See also: greatest Australian state.)

Also what Western Australia would be called if it seceded from the (markedly less-awesome) eastern states.
1.
"Westralia- quite possibly the greatest of all Australian states! Certainly a damn sight better than Tasmania, and at least it's not Queensland!"

2.
Westralian secessionist: "Secede, fellow Westralians! Recognition of the 1933 referendum's result! Off with the yoke of federal government oppression! No more being held to ransom by over-taxing dickheads in the East! Westralia for Westralians!"
Normal Westralian: "… Literally no one with a brain thinks an independent Westralia could be a good idea, you sound like a bloody Confederate flag-waving redneck from the US!"

A popular way to shorten the phrase 'Western Australia', a large state that covers the west coast of Australia.

This term has gained popularity after the COVID-19 pandemic gave many Australians a sense of pride in their state, an interest in state politics and a negative view of other states.

This may be particularly noticeable in Westralia because of Premier Mark McGowan's decision to close the border from the rest of Australia. While eastern states people and the national liberal government hated the premier for isolating them, Westralians everywhere were on board and separate from the rest of Australia flourished, with tourism actually being somewhat positively affected with less residents going overseas.

This re-ignited a conversation of whether Western Australia should be part of Australia at all and creating a distrust in the Liberal party that led to many safe seats being lost to Labor in the 2022 election, and the term 'Westralia' is really a way of showing your state identity.
Person 1: "I love westralia. It's epic."

Person 2: "We should become our own country! We have mining, agriculture, tourism - and Marky Mark of course! What's to lose?"

Person 1: "You're so right. Imagine how the arrogant eastern states like New South Wales and Victoria will survive without our food, money, wine..."

Person 2: "If we do, we should probably take South Australia, Northern Territory and Tasmania with us. You know, to be nice."

Person 1: "Nah, I'm okay with the NT and Adelaide, but we should just sell Tasmania to New Zealand."

This was observed in Western Australia after March 2020. Similar in concept to Stockholm Syndrome but in this instance most of the population of the "hermit state" fell in love with their captor in what would become the worlds largest hostage situation. It would seperate one state from the rest of the nation.
OMG those dudes in WA are cooked, the Westralia Syndrome is out of control.
Australia used to be one country, but after Westralia Syndrome kicked in things got weird!
I used to like visiting my family in the West before the Westralia Syndrome ruined things!
This Westralia Syndrome is harder to deal with than Trumps wall!
