The government is going to put in fiber optic cables sometime in the future, and the main companies had to like bid for the deal or whatever, Telstra was just like 'give it to me because I'm better'. So they didn't gewt it, so they decided they are going to DO THEIR OWN ONE, COMPETING WITH THE GOVERNMENT. Which means generally lower quality for everyone, especially everyone in large cities who has to deal with Telstra.
(yay for living somewhat regonial)
