I'm in the process of moving to the UK, so not exactly the same but some similar aspects.
One thing I find that most people over-look is the availability of working holiday visas to Commonwealth-ish countries like Canada and Australia. If you're under 30, have a look here:
Working Holiday Visa (Subclass 417)
8 times out of 10 (this is completely unscientific

) I noticed that people who have relocated anywhere in the world (either cross-country or to a different country), people have said that they didn't actually get job offers until they were actually
in the destination city/town itself. But that said, do look ahead of time and start applying for jobs from over here. For me, I work in tech so job boards in the UK are easily accessible from over here.
Also something to consider for yourself if you're looking for work: what would be the reason why an employer would need to reach all the way around the world from Australia to hire you from Canada? Unless you have a very specific skill-set that they need (or if you fit like a glove for the job), there really is no real reason why they would want to sort out visa sponsorship, or even deal with relocation costs for you.
Hope this helps a bit.
