Airlines don't fly to regional destinations because of a deep seated desire to support regional communities - they are in the business of making money. If they can't fill the seats and make money they will pull their service -simple. Ansett used to be the biggest player in regional WA, now it's Qantas/Qantaslink and Skywest. Others will move in if they think they can make a dollar -simple.
Virgin Blue will initially make much more money filling its E-jets on shorter services on the east coast. When it has maximised its capacity to make money in the east, WA would be a logical place to look for new opportunities. If you think the incumbent airlines flying services in WA have different motivation to Virgin Blue you’re dreaming!
