My friend has sponsored his wife to live here for the last two years. She is on a partner visa while she awaits PR.
She hasn't worked during this time saying that it is too hard to get a job without PR.
Is it really that difficult or impossible to get a job? I see many a travellers and students working in hospitality. So I can't really understand.
No, she's just lazy. If she's on partner visa subclass 820, she can work: https://www.border.gov.au/Trav/Visa-1/801-
