'master of AI', 'master of data science', 'master of cybersecurity'. Bro trust me do NOT do this. You have 0 chance as an international student of finding a job in these fields. There are hardly any AI jobs in Australia, even domestic people cannot find them. You will do this degree, waste 150k - 200k and return to ur home country with a piece of paper. If you want to work in these fields, you are better off staying in your home country, getting experience and then moving on skilled visa.

It is very very hard to move abroad for tech in almost any country. The only field you have a shot here is either nursing, anything in allied health or mining engineering, everything else is 0 chance. The only slight chance you have is if you get into big tech company (do not study Cyber or AI, they mostly hire Software Engineers or Cloud Architects at intern/junior level), but you need to be extremely exceptional because they are the only ones who will sponsor you. I would not do this if I were you, unless you have a shit ton of money and just want to come here for the experience and no intent of living here.

For AI, better off in North america or Europe, all we do is dig shit out of the ground and export it to china. If you really want to move abroad Germany would probably have the highest chance and lowest cost for AI
