Will I get in to Irish/Australian med school?

Just finished my last semester of my BA Psyc degree at Queen's and have decided I would like to try for med school. Because I have no research experience and weak ECs (Some volunteering in high school, working odd jobs every summer, and participating in just one club during university), I have given up on going to med school in Canada, instead looking into programs abroad. My cumulative GPA at Queen's is 3.83 and I'm confident I can score well on the MCAT after a few months of full-time self-studying.

Assuming I do well on the MCAT, is this enough to get an interview with an Irish or Australian med school? If not, what can I do to improve my application?
