Hello Divyesh,
You may have to retake IELTS. Is 5.5 the total score? IELTS requirement also differs from campus to campus, program to programs. In Australia you can pursue ELICOS if you don't meet the requirements. You must also mention which level of study you intend to do so I can guide you better.

Dear Sahira,
A few best in Ireland Trinity College, Galway Mayo Institute of Technology, Dublin Institute of Technology and University of Limerick. Will get back to you shortly for institutions in Australia and Canada. In the meanwhile please check the Ireland university websites.

approximate $800 to $1000

Hello Sai,
You have to invest in some hours every day and research on universities offering integrated Ph.D. Victoria University and Edith Cowan University are few of them. Contact the universities for availability in biotechnology department Ph.D. Don't keep yourself limited to only Brisbane as you might not find any options there.
Regards
