Hi, Congrats on the move, hope all goes well.
I will say that typically the room sizes is normally related closely to the age of the
property, this is similar in Western Europe too, the older the apartment, the larger the rooms are.
Cluster houses are bigger than
condo's for room size, I know a couple of Americans who are used to the larger properties who favour this approach.
a couple that we saw with large rooms are Laguna Park, Bayshore Park, Mandarin Gardens (all East Coast) They are also all a little older.
Good luck with your hunt. In regards to property search, I found the best way to catch all properties on the market is to use a combination of the three large sites (This one, . and iProperty) they all have similar facilities, but handle quite differently. $5K if you are willing to live out the centre a little should be plenty for what you want, you could even rent a landed for that, the rooms will be bigger but you won't have the facilities.
