His time was that Sri Lanka series, was so close to playing over thereI agree that i doubt we ever see him play for Australia in test cricket again but i will never stop praying for it.
I am not sure if he ever would have been a success at that level but CA certainly mismanaged (seemingly intentionally at a point).
I think he certainly had something to offer at times in certain situations.
Then I wouldn't have been shocked if he played in India last year considering Pete and Renshaw got gigs but that leg injury screwed his chance of being in the squad
Sliding doors if he played that Sri Lanka series and scored runs, would have been interesting if he got the chance and took it like Bison did in England
