Congrats KLexpat! When my husband and I went for our honeymoon in Australia 3 years ago, we also loved Manly so I can totally imagine what you're dreaming of! We're currently in Melbourne now, and love it here, but one day maybe we may be there in Manly too!
I'm also from KL, and if you drop by Melbourne for your recce, let me know! Maybe we can grab a coffee. Our dream started 4 years ago and gosh it just seems so surreal when you get the golden email doesn't it? Good luck with the planning!
