What year level are you guys?
Premed? MS 1/2/3/4?
Stats are useful to know, but also require context. You'll see this debated in other threads too.
But it's part of the bigger picture you want to have.
If you're a current student, for instance, it will be more valuable to you to look at the stat of recent graduating classes. Even then, I would suggest taking it in with a grain of salt (and the more open-minded medical school administrators will say the same thing - that's why some don't like to publish their stats data, they prefer to present them at conferences/talks to their current students and grads).
the other thing you have to consider in the stats is how far away the applicants were from grad. the farther you are, the harder it is to match.
It is interesting to consider that 6.81% of IMG matches were Australian, and of that only 46% of Australian applicants matched. So it's 50/50 shot, v.s. the 99% of CMGs that will match.
Also, similar to the US, south of the border and any other Western country.
Most of the matches will be in FM or IM. If you fancy subspecialty surgery for instance, good luck with that.
If you were to match in the Australian internship - most international students will match in rural/regional areas.
You can try to tip the odds in your favor - hence why everyone strongly suggests doing electives in your country of interest if you intend to work there, partly to get LORs from local physicians. Medicine consists of small circles, everyone knows everyone after a time. They won't however, know anyone as far Australia (most likely), but they will know other clinicians in the regions you apply to for residency. It's not a requisite, but it does make your % odds higher. more importantly, I would recommend the electives (if you guys hadn't already considered it) to see if you like working in that particular field/hospital/region. there's nothing worse than putting in all that effort to realize a bit later you made the wrong choice - it's okay to, you can switch out, but it's a lot harder to. I'd known people who decided not to go back because they knew their chances were higher in matching into a specialty they liked in Australia than the US or Canada (having said that, things are changing in Australia, I have no idea if I can still say that for premed or current students - currently it's harder to get PR, which is a requirement for many vocational programs).
Also, Canadian IMGs or US IMGs do sometimes get preferential treatment in the selection process.
(in terms of - as citizens, you are familiar with the language and culture, and even healthcare system to an extent, so you're more likely to thrive).
