re: Thinking of moving to Australia, need some tips.

I can tell you everything you need to know.

Australia is exotic(ish) but Canada is not. Unless you go to Vancouver which I highly recommend.

Problem with moving to another country is this: Like Europe, many countries have to show that their current needs aren't being met by natives so only then will a government allow them to hire outside the country. This isn't easy to do for many countries. If you don't go that route, you can have a foreign company sponsor you. This is hard.

You don't have a degree and usually you only get a 3 month visa before they kick you out. You also have to show you have the resources to support yourself if you apply for a visa longer than 3 months which means yes, your bank will have to give a letter stating such.

Your best option is to join Workaway. They can hook you up with a job in a variety of exotic places, provided you meet the criteria.

You could backpack and look for a job while over there but that can be risky in some countries as they could turn you in for trying to illegally migrate without having a visa allowing you to do so. When you do your research you'll be shocked to see how lax and easy it is to get into the US. Student visa, disappear, no one asks, no one checks. That simply doesn't happen in other countries.

Good luck.
