Actually it's not that bad. It's real estate market is rising, which is unusual at the moment in Australia. City for city I would prefer Perth, but Adelaide is closer to civilization, (the east).
Both have their pros and cons. Perth's beaches are pretty good, and beach property is affordable there even with the current dreadful exchange rate.
I would back the one where you can get a job. If you're husband works on houses, Adelaide may be a better bet as Perth is in a slump.
