Hello Arun,
You have a decent profile and you are eligible to apply for most of the universities in Canada, NZ and Australia. Your work experience will be an advantage, but your B.Tech aggregate is pretty less.
I would suggest you to take GMAT and score well. A good GMAT score can definitely hinder your B.Tech Percentage. Your IELTS score is fine, unless the sectional scores are above 6.
All the best.

Hello Vaishnavi,
GMAT is required to get an admit from top B-Schools in Australia. However, some Universities in Australia do accept without GMAT score. But, the VISA officer might ask to produce GMAT score.
All the best.

Hello Jeevan,
If you have plans of coming back to India after completion of your course then I would suggest you to prefer a 2 year Masters program. This is based on the fact that most of the Indian companies prefer candidates who have completed a 2 years Masters degree though you have finished it in 1 year from a reputed university.
All the best!

Hello Shamal,
Unfortunately, it is not possible to get admission in any universities with 5 band in IELTS. Though you can manage to get admission in a college, but it would be very much difficult to get a student vISA with that score. I would suggest, you retake IELTS and score at least 6.5 with no band less than 6.
All the best.

MBA doesn't require job experience. You only need to have good knowledge of your course. You need to appear for GMAT and IELTS exam to pursue MBA in Australia.

If the school or college you have applied for is ready to admit you without IELTS test then you do not require to take this test. Having said that, the schools which accept students without IELTS score may not credible enough, and based on that your Student Visa may be rejected by the consulate.
I would suggest you should take the IELTS test to avoid any kind of hindrance in your student visa.
If you don't belong to a native English speaking country then IELTS and TOEFL are basically needed to determine that you have sufficient English language ability to be able to participate in study and work related activities in those countries.
