There are a lot of online resources that you can use for finding a job in Adelaide. You can try Job Guide or the MyCareer portals.The Working in Australia has plenty of useful tips for expat job seekers.
Have a read of the Expat Arrivals page on Working in Adelaide. It provides a good overview of the regions job market.Although unemployment is high in Adelaide and wages are lower than in the rest of Australia, there are lots of vacancies for expats with lots of skills and experience.
As I mentioned, wages are lower in Adelaide. However, the cost of living in Adelaide is also far more reasonable than in Sydney or Melbourne. If you are willing to share an apartment until you get settled you can definitley find a place for around AUD 150. The cheapest accommodation in Adelaide will be in the Northern suburbs.
For more information please take a look at our Accommodation in Adelaide page.
Please let me know if you have anymore questions and best of luck with the move to Australia.
For shared accommodation - I would suggest you try gumtree.au as a starting point.
It might be a good idea to at least arrange a few interviews before you head to Australia. That way you can make the most of your time.
Hope it all works out.
