Hi all, okay so I'm British and on a working holiday visa. I have been working for my current employer for 3 months as a B and B operator. She is wanting to sponsor me on a 457 visa, although I have no qualifications in this industry. Can anyone advise which courses i would need to take to gain the relevant minimum requirements for this profession. I have looked at the visa website and the only info is a diploma but it doesn't state what in? Thanks!
