Have those who've voted for Hussey voted in seriousness?
I don't think you should ever, ever go into a Test, except perhaps (just perhaps) if you know for certain it's just a
one-off, with a rank part-time wicketkeeper. You can do it in a ODI where he has to keep for just 50 overs and not often under circumstances that particularly test wicketkeepers, but it's always a recipe for disaster in a Test IMO. We've seen how bad poor-quality "specialists" like Deep Dasgupta, Parthiv Patel, Geraint Jones (for a time), Matthew Prior, Kamran Akmal, etc. can make their team's situation.
An acceptable-quality specialist wicketkeeper who does the job day-and-day-out is one of the basic prerequistites for a Test side IMO. If your #1 wicketkeeper misses more than a one-off Test, I'd
always go to domestic cricket's specialists rather than giving the gloves to a competent catcher from the batsmen.
Also think the votes Paine's received are ITSTL. Paine averages 26.44 as a wicketkeeper in his 10 matches, as opposed to 33.25 as a specialist bat in 12. I'm not sure Tasmania aren't wasting a potentially excellent batsman by having him keep wicket, never mind whether he'd do a particularly good job as a Test batsman if keeping wicket.
