[IWantOut] 16M Brazil -> Australia/Espanha

Hi guys, I'm currently 16 years old and I live in Brazil. I take a technical course in web development, and I work as a young apprentice in the administrative area. My English is currently at level B1

Anyway, I always loved traveling and since I was 10 years old I made it clear to my parents that I wanted to live abroad, I always talked about the United States because it was the most generic. But lately I started thinking about countries like Ireland and others, but honestly I don't like this gray weather, I like sun, fun, sports.

Giving this context, I started some research, and I thought of Spain or Australia. And my family is already well on track with an Italian citizenship. The legal of Italy is already with the process, and based on that I wanted to know who went to these countries how was the experience, salaries, cost of living, if it is necessary to do a sub job or if it is to have a job in the corporate world, how was the process, costs and the like.

NOTE: I'm thinking about going to business school
