We are a family of 5 from Bristol hoping to head out to Perth in Jan 2013... I too am getting really nervous as the time draws nearer! Excited too though. Like you Les, doing it for our kids mainly, want them to experience something different, for a while at least. I know that friends will make or break the experience and would love to know how you get on when you arrive...
I am 35, my husband is 39 and our girls are 9, 6 and 5. Praying we are doing the right thing as we have a close family we would be leaving behind.
