BrummieInOz, sorry commenting on such an old post but interested to see how things are going and if you have made any progress with your move to Oz?
I too am looking at the possibility of moving to Oz as a plumber and yes it appears to be very difficult in some cases and expensive.
There’s pros and cons for me, I have over 20 years experience in plumbing, heating and gas but I am 41 which is against me really and also doesn’t give me long to get a visa sorted.
I also have a family of four so lots of expense and looks like I would need to take some form of English test to get anywhere near the points required.
Scary costs really, I have only just started looking but think it will be around £10k on visas, £3-4k plumbing tests / paperwork and then moving costs so I think £25k minimum is where I’m at and to be honest I don’t think I’ll even make the points
