About the exploration and development of Antarctica, there is a very famous treaty among later generations known as the Antarctic Treaty.
The Nanjing Treaty constrained activities on the special continent of Antarctica that has no permanent population, ensuring that any exploration and expeditions there serve only peaceful purposes.
But before this treaty existed, there were no restrictions on the explorations of various countries in Antarctica; the ice, snow, and bitterly cold weather were the greatest and the only constraints.
This also had an advantage for Arthur: if he could claim most of Antarctica, or even the entire continent, before the Antarctic Treaty was established, Antarctica could serve as Australasia's backyard garden, and he could also deploy corresponding military facilities to extend Australasia's military influence to more distant areas.
