I was in Australia last winter and if i remember correctly, you have to take a short course, 1-2day, in order to be a bartender, waitress etc. If you take something in Canada I'm sure it would be helpful. not sure tho if it would exempt you from taking a course there. i didnt work in oz but always saw job postings in hostels. regardless of what you decide you will be able to find work there no problem...everyone does it!! hope this was helpful.
