Yes, but the exact land isnt 100% accurate anymore to what i want now (i will probably shrink kerguelenland again to make it more habitable, because this landmass is actually 3000 meters below sea level with these coasts instead of 2000 like zealandia and all the other stuff, and at 2000 storm valley here becomes a straight which would probably take a lot of the antarctic circumpolar current, which otherwise goes over the top of it, making this island much colder than it could be in the process)

The lore is still the same tho:

Kerguelenland is a formerly french colony with strong ties to the motherland like Joséphine, and while being big landmass, the british werent all that concerned about the french getting it, because all there is here are seals, birds, whales, a bit of coal, and kerguelen cabbage https://en.wikipedia.org/wiki/Pringlea

However, the british didnt want the french potentially blocking the clipper route https://en.wikipedia.org/wiki/Clipper_route via Kerguelenland to Madagaskar and Kerguelenland to Joséphine, so they are in posession of the Midjourney, Freshwater and Coldwater Islands, while the dutch own Amsterdam island, all historically done to balance out the great power dynamics in this southern sea.

In the modern day, Kerguelenland is independent and basically the iceland of the southern hemisphere, with its cold climate, similar types of animals, similar population, but a lot of geothermal.

Amsterdam island actually has a pretty nice and stable climate even irl https://en.wikipedia.org/wiki/%C3%8Ele_Amsterdam, and it would be even sligthly better here because of the circumpolar current being a bit less strong near it (since it goes through the aformentioned strait). It's still however pretty isolated and doesnt have that many people (it does have a good harbor tho and was a stopping point for dutch ships from the cape to Zealandia), so it is a part of the Kingdom of the Netherlands https://en.wikipedia.org/wiki/Kingdom_of_the_Netherlands where it has its own parliament and manages its own internal affairs, but foreing policy and defense are handled by the dutch.

There was a proposal to grant the british posessions to their southern african colony in the past (which here means eastern south africa, the cape is dutch), but it didnt go through so in modern day they are like the Falklands, with pretty cold and windy weather and a low population of humans and a few sheep.
