Here is a list of US (and other countries vet schools accredited)

Like PP said, we cannot tell you where you are most likely to get in. Nor can we give you any real advice on where to apply. It is all up to you.
If you're looking at going abroad and are concerned about your GPA being a little on the low side, consider Ross or SGU. SGU (and maybe Ross, too) has a program where you are tentatively accepted into the DVM program,
IF you successfully complete their 1-year Pre-Vet program. So you'd commit yourself to 5 years of schooling after your prereq's are completed.
A note on studying abroad: It is incredibly expensive to move, live, and pay tuition at these places. Melbourne for example (just with a quick google search) seems to be about $230,000 USD for the program. Add in cost of living, cost of moving, visiting home at ALL during your 4-5 year stay and you will have a very sizable fee to pay back.
Ross and SGU are comparable in fees and tuition.
It might behove you to check into US schools, too. Living abroad might not be as fun as you'd like to think. Western (California) looks at the entire applicant, not just numbers and is a favorite choice of those who are concerned with their GPA but not the cost (it's about on par with going abroad).
Your best bet on getting in is probably your In-State (IS) school.
You said going "back" to school. Have you previously attended college? How did you do in those courses? They are not erased from your transcripts, no matter how old they are, and will have a definite impact on your current GPA. Keep that in mind.
First step? No need to take any fancy steps. This is NOT too early for you to be considering admissions requirements, and is even a little late. You need to make sure you will have ALL prereq's finished by May of the year you plan to apply. So in two years in May of 2014, you will apply for the 2015 school year (Class of 2019). Get started with basic math and science courses required by almost every vet school. Biology (for science majors, no "Intro To...." courses...those won't count as your prerequisites), math (college algebra, trig, statistics), physics, chemistry (general, organic AND biochem). Some schools require Animal Nutrition or Calculus, or some other random pre-req. You need to narrow down your school choices, and fulfill the prereqs for the ones you know you would/could (financially, distance, whatever) attend.
