I wonder if any international criminals have sought to evade capture on that continent. It would be the closest thing to going to Mars
One of the researchers he interviews about it describes how he lives life with no real home and always has a bag packed with enough essentials to go hike out into the wilderness anywhere in the world--Herzog asks to see the bag and the person happily pulls out an enormous pack and starts pulling out stuff like an inflatable pack raft, stoves, tents, etc. The big point is that you have to be a special kind of person that's not really attached to modern society to go live and work at the end of the world.
Many, many years ago I was in the Army and served with a man, Corporal White, who was the oddest person I had ever met. He was probably the best soldier I have ever seen, but refused to take anything seriously and treated the Army as a game to be played (as one should).
Anyway, he put in a DA4187 form, a personnel action request form, with roughly four words on it: "request duty in Antarctica", it worked its way up the chain of command, and after several months a telegram (the army sent telegrams called PERSGRAMS up until the late 90s!) arrived assigning him to duty in Antarctica.
He spent about six months down there, in his words "moving around barrels and crates and playing Nintendo", and came back engaged to a scientist.
Now he and his wife are itinerant adventurers and I don't think they've lived anywhere for more than six months in the last 25 years.
Maybe if you somehow assume the identity of somebody working at one of the research stations and are able to do their job? If I was going to write a book and make it halfway plausible that's how I'd have the character do it. But unless I'm mistaken everybody has a fairly specialized job and/or is a grad student or professional scientist.
edit: There are some perhaps "somewhat" unskilled positions, I see, such as "Positions in waste management, food and station services, retail, lodging coordination, and more."

There are some Antarctic cruise ships that come in and do a day trip. I hear the NSF hates this and makes sure everyone gets back on the boat.
They plan their logistics over a year in advance. Anyone showing up unexpectedly is going to throw that off.
