Hi guys
We are 39 & 43 (OMG!) and are hoping to be in Perth Nov 08. Likewise we have no children going with us but have the advantage of a friend over there. We went in Dec 07 and everybody is really friendly. Our friends friends treated us like long lost family and welcomed us into their homes - it was great.
You will have no problems making your own friends over there unless you are really unlucky - which I doubt. Whereabouts are you planning on going in Perth and when?
Maybe we could get together.
