I lived in Brisbane at the time of my wedding. We also went to WA on the honeymoon, stayed mostly at Yallingup. Also, went on a 3 day trip of the Great Southern including Pemberton (did the Gloucester Tree) and abcruth, spent 2 days with sore legs afterwards also.
18 months later, went back for another holiday (1 kid by then), after paddling up Margaret River in a canoe, we daydreamed about moving there to live. Took another 2 years (plus one more kid) and we did it. Have lived in the south west ever since and won't be going anywhere else. Except for visits of course.
