TIL that Antarctica used to be called Australia until modern-day Australia stole its name in 1824, which left the continent nameless until its current name was adopted in the 1890s.

It appears New Holland wanted a name change……

From Wikipedia -

Belief by Europeans in the existence of a Terra Australis—a vast continent in the far south of the globe to balance the northern lands of Europe, Asia, and North Africa—had existed as an intellectual concept since classical antiquity. The belief of such a land lasted until the discovery of Australia.

During the early 19th century, explorer Matthew Flinders doubted the existence of a detached continent south of Australia (then called New Holland) and thus advocated for the "Terra Australis" name to be used for Australia instead.[8][9] In 1824, the colonial authorities in Sydney officially renamed the continent of New Holland to Australia, leaving the term "Terra Australis" unavailable as a reference to Antarctica.

Terra Australis .. That's it!
