Yes I made the move over 10 years ago. I recall initially thinking how green & lush it seemed compared to Perth. Its vast and sprawling which at first I enjoyed but soon realised it was a terrible hassle trying to get from north to south etc, unlike Perth where a journey was much easier. It feels more a part of Australia though. Perth being so remote it can sometimes feel like the place is forgotten, or at least the powers that be over there like to think themselves hard done by and left out. So much so that they then deliberately arrange a bank holiday the week after the rest of the country - just to be awkward!
That being said, Queenslanders are too, especially regarding NSW and rarely miss the chance to moan about it.
When I moved it was noticeably more expensive here, though I believe Perth may have caught up in the intervening years when it comes to housing etc. I still think some items of groceries and eating out are extortionately priced here and have often wondered why Brisbane is never mentioned in the list of the worlds dearest places to live, when those surveys are trotted out.
Weatherwise, personally I don't find it any different to over there. In the summer its too hot and it can be cold for a few days in winter (colder and for longer than I can ever recall these past 3-4 weeks mind). I'm not one who can argue that its a dry heat rather than humid, the fact is that both places get too hot for me at times.
I don't enjoy the fact that they don't have daylight saving here either. Neither did Perth until I left, but you'll have known nothing else. I don't think if I stay here another 100 years I'll ever enjoy not having light nights during summer, instead its dark before 8pm....on the longest day (which begins at 4am, which is still the middle of the night to most sane people).
Of course the Gold & Sunshine coasts are close by and I especially like the fact that Sydney is only an hour or so away by plane, but overall I prefer Perth, Fremantle and their suburbs over anything Queensland has to offer.
If you're not aware already, when you get here you must pay a visit to Chumley Warners British Fish & Chip shop in Birkdale near Wellington Point- just like you're used to from back home but consistently 1st class, always jam packed with punters & 1000% better than any Aussie fish bar could ever dream of.
