Hi Connie,
are you sure that as a spouse you can't leave the regional area? I'm not expert in regional migration, but to my knowledge any other visa I know allow dependants to do what they want. I know people sponsored in the city that are obliged to respect the restrictions of the visa, but their wives can work as normal Australians. Same thing for students husbands'wives and so on.
Certainly, in a rurale area there is not much to get in term of placements. Also the problem is appearing in every city. Placements are rare and some are expensive. Many people are complaining about that especially in NSW, VIC and QLD.
Are you part of our study group? I personally don't think we have people in SA at the moment who is involved in the process. We used to have. But can you then get a placement in Adelaide for example?
Let me know, I might try to find someone of the old candidates over there and ask for info. Also make sure you are not allowed to travel to another States.
