Australia

The yearly fees varies between AU$ 10000 to AU$ 16000 for UG.
Below mentioned are the best universities:
1. Murdoch University.
2. Victoria University.
3. Sydney University.

No, it does not matter.

No, it is not the best country for journalism.

I wouldn't suggest you any of these because the living expenses in these countries is just of the league. In my opinion, go for Germany or New Zealand. Germany offers international students scholarships that result to very less fees or even no fees.
New Zealand is also offering many scholarships. The living expenses is quite low in these countries as compared to those countries which you have mentioned.
I hope it helps.

You need to score 60% in Bachelors degree.

Australia is slightly easier but only if you have the qualifications listed as per the SOL, you must also have a job and have the skills. Having said that, obtaining PR is slightly tough in Canada as there is no separate pool for international candidates and work permit schemes follow provincial rules and nomination, so it becomes tough. Irrespective of both the countries you must have the necessary skills and qualifications.

Ten years is a long period, market trends keeps changing every year. I would suggest you to keep reading business and economics news to keep yourself updated.

All of these countries are the best for civil engineering. The best country is US because most of the top universities in the world are from US. (Like MIT, Harvard, Stanford, Yale, Priceton, and many more). Also, placement (incomes) are higher than other. So, I will suggest US.
