Let say I am a recent graduate in a technological field in 2018, for instance AI, and I want to work from 6 months to a lifetime in Australia. Having seen that most job offers require people to have a work visa, I have been visiting the work visas webpage of the Australian government. Then, one can't know if he has to apply for skilled visa with the SkillSelect program or another. Yet, for this program one has to be nominated by an approved Australian employer.
There seem to be a contradiction then : I can't present a valid working visa to a company asking me to have one if I have first to be approved for it.
Subquestion : do you know websites for Australian job offers for just graduated students ?
