GRE and IELTS are both requirements for any form of study you wish to pursue. As far as an undergrad is considered, you may find certain colleges in Australia which only require an English proficiency test and not GRE. IT is important to scout such colleges and build a proper profile so as to allow a better view of things. With the recent changes, the score barrier for English proficiency tests has gone up and certain people find it difficult to achieve the same. A better alterative would be to enroll in some form of study which would then allow you to scale up to a PR and a job opportunity in Canada. One of the interesting one's that I recently encountered is this Study & Work programme where you basically get to do a course while earning part-time and once you finish the course, you can work full time for about 6 months.
