Re: Newbie from Australia <---------
Welcome to CoolAntarctica.
What you need to do is find the organisation responsible for Australian operations in Antarctica. To give you a clue it's called the Australian Antarctic Division! You might just find some recruitment info on its website. It shouldn't be too hard to find through Google, after all you did manage to find us here.
Even though you still have to complete your nursing degree it might be worth your while making contact and talking to someone there as to what what opportunities there might be for you and the sort of expertise AAD is looking for.
Best of luck with both your nursing career and antarctic aspirations.
