Probably because when just about all of the major ports were being designed, there were hardly any international pax into and out of anywhere but SYD. There were also only two domestic airlines flying, neither of which had an international arm, and who usually had a dedicated end each of a common domestic terminal, or their own terminal. There were also very strict regs on what types of operations could occur on aprons and in buildings gazetted for international operations. It was probably easier just to separate them.
