True, but so do Telstra, Australia Post and a number of other privatised companies.
Comparing apples and oranges Worrals!
Telstra has a huge advantage in infrastructure terms that makes it hard for anyone else, no matter how much money they have to come in and compete. If it wasn't for some services that I can't get from anybody else I would dump Telstra in a instance.
As for Qantas I havn't done much traveling in the last several years, but in the past no matter how much I wanted to use them the hip pocket wouldn't allow it. Sentiment will only let you go so far.
