Bandwidth!
Great result for all parties involved, and the extra distance between receiving stations will just make it better.
I heard a Podcast outlining the bandwidth requirements of the SKA. It will be sending Exabytes of data each day and each telescope needs to be correlated with each other in real time.
I want to know who will be laying that much submarine data cable between Australia and Africa? Off-the-shelf cable isn't going to cut the bandwidth requirements (petabits per second).
