I'm in the much derided on here Perth, and for us it's been a fabulous move. We'd been to east coast before, but never this way before we made the move, but all knew as soon as we landed it was the place for us. If we'd been on this you'd all have been howling with laughter, we picked Perth based on the number of average hours sunshine it has.
House prices here have been on a bit of a decline, and cost of living has definitely stabilised compared to when we 1st moved.
We definitely do not work harder than in the UK, I work a 9 day fortnight and leave at 4 every day. We both work in IT, and the wages are significantly better than we were earning in the UK (north of England). Even assuming $2 to the pound I earn 4 times what I was on back home. In 5 years we've not had to scrimp, have had nice holidays both abroad and in Margaret river, which is for me the most beautiful place I've been and have still managed to save enough for a deposit on a 2nd property down south as our holiday home / retirement property.
There always seems to be this fallacy that there's no seasons, and it's same hot weather all year round, which is definitely not the case. Winter is cold, spring and autumn tend to be absolutely beautiful, mild sunny days and summer hot and dry. It's a nice dry heat over this way, and there's a lovely sea breeze that makes it much more bearable, so beach is fab, even on 35 + days.
Agree with previous poster, we have decent insurance and the service we get is fantastic. Easily get same day doctors appointments, they're open till 8 most nights and Saturdays. Have had a number of trips to emergency, thanks to my son's love of scootering, and treatment has been free. Recent broken leg cost us nothing about from the hire of crutches.
So it's not all doom and gloom, and can definitely work out, even for people like me who make decisions on weather charts, pictures of beaches and very little else.
