Hi Liz
OK. You have time to get a skills assessment organised and in the beg, followed by gettig the visa application completed and in DIAC's office before your 45th birthday, but you do not have time to hang about, lassie, because getting all the paperwork together invariably takes longer than people think it will.
Read Booklet 6. Focus on the skilled idependent subclass 175 visa for the moment and focus on doing the whole thing via your skills and yourjob because you are still under 45.
Swot up on the criteria for the different bits of the points test and work out whether or not you have enough points for an s/c 175 visa. The links are below.
Please let us know how you get on.
Best wishes
Gill
