ok, chemical industry in australia? pretty much everywhere.
it really depends on what industry your after - petrochemical? mining? pharmaceutical? food? chemicals? water? energy? environmental? nuclear?
do you really have a preference, and do you have any previous experience?
it also depends how far out from the major centre you wish to be. for instance there is a polyethylene plant 6km from the heart of sydney, and there are mining facilities 600km away from the next community.
a good resource for general information on the different industries available is at www.chemlink.com.au
if students have gone to exchange to australia before, maybe someone in your department at uni can help you with how previous students went?
im a chemical engineer working in the process control and instrumentation, and have a reasonable good idea on whats around, but it depends on what your after.
