I don't really think it's a matter of not applying if you don't want the job, more a matter of taking the job once the T&C's have been outlined - which hasn't happened yet.
The first phone call was definitely more for market research. There is no harm in going to the interview, finding out FACTS and THEN making a decision.
Pretty much everything to date is speculation and brackets with no formal decision on T&C's been made.
However, there will have to be some significant improvement in dollars (or a fantastic roster) for V Australia to get the people they're looking for.
