Hi Tony
Welcome to Poms in Oz.
You need to read the DIAC website to within an inch of its life. Please see here:
http://www.immi.gov.au/
The DIAC website will become your bible until you have your visas!
The following links may help you to get started with itL
http://www.immi.gov.au/asri/a-z.htm
http://www.immi.gov.au/skilled/gener...oints-test.htm
Additionally, it is essential to study Booklet 6 very carefully if you think you may be eligible fo independent skilled migration, and Booklet 5 tells you about sponsored skilled visas.
Do some research fist before you worry about possible sponsorship at this stage, I suggest.
Sing out as more questions crop up because someone will be able to help and a couple of Registered Migration Agents also very kindly help with the forum when they have time.
Best wishes
Gill
