Alright, so Canada and Australia are both great options, but they have some key differences. I've never studied in either, but I did a lot of research as I considered both.
Cost-wise, Canada is generally cheaper, especially when it comes to tuition. But keep in mind that some Australian universities offer scholarships that can make it comparable. The cost of living can vary a lot depending on the city in both countries. Toronto and Vancouver are pricey like Sydney and Melbourne. But there are cheaper options like Montreal or Brisbane.
Job opportunities depend on your field. Both countries need engineers. Australia has a strong mining sector, if that's your thing. Canada has a booming tech industry, particularly in areas like AI.
Lifestyle is where it gets really subjective. Australia is known for its beaches and outdoor lifestyle. Canada has four distinct seasons and offers things like skiing and snowboarding. Australia is probably more laid-back in general, but that's just my impression. Canada can be a bit more⦠serious, maybe? Also, remember the distance - Australia is way further from Europe/Asia if you plan on travelling.
Honestly, you can't go wrong with either. Look closely at the specific programs you're interested in and compare the costs and career prospects. Good luck!
