What you'll need to do, depends on what state you'll be living in. The bad news is that it's a bit of a long haul. Chances are you will have to work for about 12 months as an assistant to a licensed electrician before you can go out on your own. https://www.tradesrecognitionaustralia.gov.au/electrician-general-and-special-class https://pathwaytoaus.com/blog/how-to-work-as-an-electrician-in-australia/

Dental work in Australia isn't covered by Medicare. It is all private, so you will have to pay for it. You can get private health insurance, but there is usually a waiting period (six months or more) before you can claim for more expensive procedures like orthodontics. When you first join a health fund, the benefit for orthodontics is often fairly low and it improves the longer you're a member. Not much use to you, I know, since you'll be arriving brand new. This article is basically an ad for a cheaper alternative to braces, but it lays out the costs for various kinds of orthodontics fairly well. https://www.ezsmile.com.au/cost-of-braces-australia/

I agree. I'm guessing the real motive is not for the sponsor's benefit but for the family. They think they have a chance of a better life in Australia if they can get the visa. However as Quoll points out, the waiting time for the visa is at least 7 years, and that's a long time to survive without being able to work, and having to pay school fees. Also there's always the chance that the visa will be rejected.

You cannot convert the 600 visa into anything. It allows you to come to Australia and speak to employers, and see if anyone is willing to offer you a job and sponsor you. However, employers can only sponsor you if you have the right qualifications and experience, which are specified by the Australian government. So you need to speak to a MARA registered migration agent to find out whether your qualifications and experience meet the government's requirements first.

It depends which state you are in.

Now all you have to do is get a job there...which wouldn't be hard to do from Melbourne, since it's only a quick plane hop.

Your brother is not a parent, therefore he can't get the 143 visa on his own merits. It is a parent visa. Your father was the applicant and as he is deceased, the application cannot proceed. If you don't tell Immigration that he has died, you will be committing fraud. To be honest, I'm not even sure if his 173 is still valid if the main visa holder is not living. I suggest contacting a MARA registered agent urgently to find out what his status is.

I'm not sure I understand the question. The income stream will be taxed as part of your total income, whatever that is. You get a tax free threshold of GBP 12,750 per year and then you'll be taxed on the rest of your income, whatever that is.

Yes, you'll include your partner and children on the visa as your dependents. Is it a 482 visa (which is just a temporary work contract for a few years), or a 186 visa (which is a permanent visa that lets you migrate to Australia)? A 482 visa can be a fantastic opportunity for an adventure for your family, and it is possible that you might be able to stay permanently after the contract ends -- but it's far from guaranteed, so make sure you understand all the in's and out's of the deal. It can be a very expensive adventure if you don't plan carefully.

Worth pointing out, that could just be the difference between city attitudes and country attitudes anywhere in the world.

When did you apply for the 143? Do you have a queue date?

I'm guessing your wife has "indefinite leave to remain" in the UK? The thing is, "indefinite" does not mean indefinite. If she leaves the UK for a continuous period of more than two years, she'll lose it. So if Australia doesn't work out and you decide to return to the UK after a couple of years, you'll have to go through the whole process of getting a new UK spouse visa from scratch (and of course, that means meeting the financial/job requirements). I assume you've done it once so you know how it works.

Your qualifications, experience etc are all irrelevant to the "last remaining family member" visa, because that is based entirely on your family relationship. However I doubt the visa will suit you, as there is a very long waiting list (only a small quota is granted each year). Based on the current waiting list, if you applied today, you would get your visa in about 25 years' time. The Business Innovation Visa is currently closed to new applicants, pending a review. This thread is relevant, and @Steve Elliott (who posted on that thread) is probably your man to talk to about it. Your other option would be to apply for a skilled visa (189 or 190), but I have no idea whether you'd be eligible. You'll need to research and act on that very quickly, though, because you're fast approaching the point where you'll be too old (45 is the cutoff age). Sadly it is a fact of life that Australia is no longer crying out for migrants. It's still easier to get into Australia than to some other first-world countries, but not by as much as you might think.

Even if you hadn't surrendered your SA licence, it wouldn't be possible to renew it because it's been more than 5 years. I tihnk your only choice will be to transfer your UK licence, unfortunately.

What questions do you have?
