Here is the Australian Electoral Commission documentation on how to register a political party. It includes the requirement for “A Microsoft compatible electronic membership list (and paper copy) providing the following information”.
So a prerequisite for registering a political party appears to be the ownership of a PC running Windows. While it may be the case that I could create a plain text file on a Linux machine and append some CR characters to each line, or create a CSV format spread-sheet/database file the most common interpretation of this is likely to be that MS-Office is required.
