Hello all,

I wanted to ask for some advice regarding a situation my friend is currently facing: as a PhD student in an European country, they've received a national grant for a research project. As part of this project, they've arranged a visit (e-mailed the prof., explained all the details, got confirmation and a formal letter) in an Australian research lab for a few months.

This is where our question comes in: What sort of visa should they apply for? A cursory overview of the Department of Home Affairs' website ( https://immi.homeaffairs.gov.au/visas/getting-a-visa/visa-listing) shows several visa types which could potentially be appropriate in this case.

What sort of visa should they apply for? Alternatively, where can they seek additional information and guidance, aside from the aforementioned professor or the university? Do you think sending e-mails is sufficient, or should they try international phone calls? Any help and pointers would be greatly appreciated!
