Just been doing these for another one of our forums based on the ABS data. I know for Victoria it was spot on but as I don't know Adelaide I suppose only the members on here who currently live in Adelaide can tell us.
< 850: Forget it
850-950: Not that great.
1050-1150: Good area
1150+: Really good area
