Two things worked against Bevan.
1. He was no more a youngster and was pushed for a place in the side by Hussey, Clarke etc.
2. He was pretty poor in the last year of his International career. In fact in 2004, he averaged just 27 from 12 matches.
Hussey's bad run in ODIs have lasted just 3 matches, and he does not look replaceable atleast in ODIs for now.
I know how well he played against the Bangers and the WIndies, but the last opportunities I've actually had to watch him have been at home and in the World Cup. Let's see his record from these games:

Two half tons in 27 matches (19 innings). Not the most convincing form.
Again I'll reiterate that these are only the games *I've* had the chance to watch over the last couple of years.
