ChloeB - try Dan Murphys for Black Label wine (I presume you mean the MvGuigan one) - it's currently $6.60 a bottle, has been down to $5.60. And it's £8 in the UK - result!
Perth - we're here and to us it's fine, it is limited if you want nightlife and lots of variety, but the beaches are lovely and within walking distance of (relatively) affordable houses, which I think is different from most of the other states. But it is a Looooong way from anywhere.
Crankypants - I can't see a lawyer getting much action over here, offices seem to be outposts rather than big centres, although again I'd imagine you'd have less of a commute and again you'd be close to the beaches whereas I guess DH wd have to be working in Sydney/Brisbane CBD which are pretty major commutes I think, always depending on how many megabucks the firm is paying of course 
But regular travel over East would be a killer, it's a 5 hour flight, and a 2 hour time difference, so it knocks out a day in one direction, plus the cost of tickets is rarely cheap.
Oh, and trains are ok as long as you live further out, I always get a seat on my train at 8am, and I'm 30 mins out from the CBD, although I admit I look up in horror at the scene of sardines when we get to within 10 mins of the city. Trains are amazingly reliable though, as there are no lines crossing like in the UK, and they stop and go quickly - they're like very long overground tubes really. Driving is uniformly horrendous however, the freeway is chocker from about 7am at the latest, and from 4pm onwards and parking is a fortune. And the locals are really bad drivers. Really bad. That's why I stick to the train!
