Canada

Canada has been good for many years. If you study there you get a better chance of getting job there. It is still the 1st choice among Indians.
But at the same time Australia is growing very fast in terms of giving jobs to Indians. The job prospects are more. Again, if you have Australian degree, you get better chance in getting jobs here.
In comparison, both are good but I think Canada is more well paid (But taxes are very high). So, I would suggest go for Australia. Rest is your decision.

Even if the salaries seems to be higher in Canada but the government taxes are almost 55%, so by the end of the day you are left with too little. In Canada, the companies give more preference to those who have Canadian college degrees. Australia and New Zealand are better places with reasonable taxes.
