I think you haven't gotten any responses because your question is unclear. Are you asking whether Australia requires US applicants for visas to have $5,000 in their checking account? There are probably very few people who know that information.

Yes, you need to have the $5,000. Don't play with that or they can deny you.

anyone??

Hi, quick question. I am from US and trying to obtain a working/holiday visa. Do your au pairs really have 5,000 dollars in their bank account to show at immigration? Do you think this something to be worried about? I'm 18, and no, i don't have 5,000 dollars in my bank account. Think it's a big deal?
