Spent Feb in Perth and I loved it.
I don't much care for cities but Perth was quiet enough for me to feel happy about going into the city.
I like the lifestyle, the outdoors, the freedoms, and the relaxed attitude.
I like the lack of greed that appears to be there, free bbq's, friendly assistants, no back to back queuing and chocablock roads.
Granted it was 40 deg some days and I was up in the hills overlooking Perth so it was a bit hot at times, but it's only a couple of months of the year.
I guess it depends on what you want and the lifestyle you already lead. For me the fact that the nearest other civilisation is many hundreds of miles away doesn't bother me.
I only go into the local town about 3 times a year, if that!
I'm not interested in clubbing and night life, much prefering to have friends around or visit friends.
The pound gets a lot of dollars too at the minute and thats a bonus.
So I went thinking it would be too hot for me to live there, I went out thinking I wouldn't like it. I came back thinking about booking my next trip
Would I live there ? Take my 3 kids and ship us all to the other side of the world ? - Oh yes !
