For example bringing frozen people to Antarctica would be costly, but you would save a lot of money for keeping them cold for centuries. In a long term...
I'm not sure you would. From what I recall the corpsicles need to be stored at colder than Antarctic temperatures. That means you need to have a significant energy source or steadily import liquid. It could be cheaper to just buy slightly better insulation to offset the greater temperature difference between the respective external environments.
Potentially of interest to my fellow antipodean LessWrongers. Stasis Systems Australia is a company seeking to start a cryonics facility in Australia. Their website is pretty sparse, but they just sent out a mailing list update on how they are going, and it doesn't appear that the information therein is located in any news section of the website, so I thought I'd post it here.
