First job is to check that one of you has a skill on the Skills list - use the link that the previous poster gave.
Next do a quick assessment to check your points. The right number of points (120 I do believe) could lead to a skilled independent visa. This is a golden ticket that will allow the person with the skills, their spouse / partner and any kids to go where they like in oz and do what they like.
I don't know very much about the other visas I'm afraid. I'm a teacher and got enough points so applied for a skilled independent 136 visa. My husband is named on the visa so it's just one application.
Hope this helps to start with and welcome to Poms. We are a friendly group and will try and help folks where we can.
