I agree that it is all very confusing.
You need to start with the occupation itself, which is here:
The most usual problem with British Butchers is that they have spent several years learning the job but they do not have any paper qualifications (eg an NVQ3) to prove it. Without the paper qualification, it is impossible to get a positive skills assessment from TRA (Trades Recognition Australia.) Without the skills assessment, it is impossible to get State Sponsorship.
That said, you are only 36. The British Butchers that I have come across who have had problems with this issue since September 2007 have all been 44 or older. So for a relative young 'un like you, it might be that this is not a problem any more?
Do you have a positive skills assessment from TRA? If you have then you will be able to say "yes" for certain. If you do not then you will not get sponsorship from the Australian Capital Territory.
If you do not have a positive skills assessment as yet but you would be able to get one, it would probably be best to get a Registered Migration Agent to give you a hand with the whole thing, in which case a firm called Go Matlida can be relied on to do the job well for a reasonable price:
Are we OK on the TRA assessment bit, please?
