David,
I am a pastor in the Lutheran Church and the congregation in Temora called me to serve them there. Cairns is a beautiful place but I'm enjoying Temora as a community. And that is what stands behind my original answer to Tomo's question. As a town and community it is a great place to live. It has all the amenities we could want for as a family, without the hassles of city living.
Your concern regarding the humidity is well founded. A lot of people cope; many go from one air-conditioned building, to their air-conditioned car, to their air-conditioned workplace, then back again. A few people like the humidity and all power to them. My advice to anyone thinking about moving to Cairns would be to visit during the wet season to experience what this is really like. I didn't like the humidity, but the paradox is that this is the time of the year that is most exciting in FNQ. Mind you, lows of high teens, low twenties is pretty good during June/July as well!
Cheers,
Mathew
