I don't know what the European pilots coming to OZ have to do, to get an OZ license.
If you want to get a JAA license, then you have to pass all those 14 exams in an 18 month period, unless you got command time on a medium size commercial jet,
then you'd be eligible to sit for just one exam which is airlaw.
The Western Australian Aviation College conducts regular distance learning courses, where after each group of subjects that are completed,
you'd then have to attend a one week brush up course to knock over 5 exams in a few days.
Each exams costs around 80 pounds.
Some people have got the apetite to do this and perservere with it.

I mentioned this to an instructor years ago and he said to me, after you finish all 14, then you can do another 14 for me.
The JAA exams are a nightmare to complete, it's going to cost you at least $10K to finish it all.
Some people can do it!
I strongly recommend you do the English exams as it's recognised by all Euro JAA bodies.
Goodluck.
