Hi Annemarie
Welcome to PIO.
Have you checked out the skills in demand list on the immigration website
Department of Immigration and Citizenship - thats your first stop - however, im positive that your hubby will be able to apply under his current job, providing he has the years experience etc that the criteria asks for.
As regards jobs, perhaps check out a few of the job sites such as
SEEK - Australia's no. 1 jobs, employment, career and recruitment site and
Job Search - Australian jobs - Job listing - Find a job - CareerOne and they might be able to give you an idea of positions available etc. Failing that, a quick post on here should be sure to get some responses from guys already in the same field out in Oz.
You could also chat to a migration agent about your options, they all offer a free 15-20min chat over the phone and might be able to answer any questions you have about the skills assessments and visa applications.
As regards areas/suburbs, have you any idea where in Oz you would like to be? Perhaps you might be guided by the job opportunities in each area, climates (does vary throughout Oz), housing prices, schools, any friends/family already over there etc etc.
You say your skills are also on the list - you can either apply for permanent visa under the general skilled migration, or if you can find someone willing to nominate you for sponsership, go down that route. However, there are restrictions with the sponsership route - would suggest you chat to agent again in regards to this.
Anyway, hope this helps a little, others are sure to add their comments too in due course.
Any other questions, feel free to ask away, thats what we are all here for!!
