The Australian work visa is even friendlier than the Canadian one. I'm not sure how the Australian citizenship process works but it used to be you could apply for permanent residency shortly after going there for University. I think it's a bit stricter now but worth looking into.
Yeah, Australia also has a very good immigration policy. I seriously consider applying after I finished college in Brazil.
But the hack I described is as a way to possibly end up living in the US. Being an Australian citizen doesn't help much there, while being Canadian does.
Sorry, I meant, as an Australian citizen, you're eligible for an E3 work visa to the United States. You need a bachelor's degree in the relevant field or equivalent work experience, companies just have to spend 20 minutes filling out an LCA and prove they're paying prevailing wage (none of the "prove an American can't do this job" song and dance that makes the H1B so expensive), the quota is so ridiculously high it will never be reached and it's 2 hours at a US Embassy for a 2 year visa.
The only downside is it's a non-immigrant visa so you come in on an E3 then convert to a H1B at your leisure and apply for a green card.
