I want to know the answer to the following question:
What did people once believe could not be found further south than Australia?
All the background I'm provided with is that "Integral to the story of the origin of the name "Antarctica" is how it was not named Terra Australis—this name was given to Australia instead, and it was because of a mistake made by people who decided that a significant landmass would not be found farther south than Australia.". Is that enough to answer the question?
Answer: yes
