I only used to get condensation when I rapidly cooled the tank and on humid days. Perth summers are usually always very hot and dry so it's not really a issue most of the time for me. I do however have to top up the tank frequently.
from memory, one member (also in brissie I think) had a custom stand made and the tank basically sat in a tray and the condensation collected in it.
It is a problem as of course as the stand will eventually fail due to water damage and the wood expanding. it's a very real issue if your stand has plywood or chipboard on it somewhere, as some tanks that are mass produced branded ones (aqua one, jebo etc) and come with matching stands mostly use laminated chipboard in the construction.
if you have a metal stand, you probably won't have any issues. keep in mind too that you'll get lots of condensation if you use a chiller to cool your tank.
