Vaccinations
Hi,
if I were you I would try to get as many done in Australia as you can (or at least, what you can get for free/refunded using Medicare)
If you get them done here, they will charge you and you will not have much money AT ALL in the first salary after the advance. The first salary you get is quite low (even though you get the advance you need to save it over a month or two) and if you try get nearly all done in your own country they usually don't charge for one or two
(I missed yellow fever as it was about $80 aus and couldn't get an appointment at the travel clinic but EK gave it to me for free as I did everything else.)
Up to you but you'll be poor enough the first few months without deductions for vaccines.
