Same as above. Been there did that and never again. So much documentation and you have to be prepared to put sufficient if she's unable, funds in her account, plus show that evidence. Could you trust her if you split in the first month. I chose 3 months, but after one month, too much responsibility when they get homesick and demanding. But felt justified to put sufficient for a return flight, which I had to book and ensure they were on that flight back. Then funds for the privilege on return. A nightmare of proportions. But good luck with Australian embassy and agent. Possible all the same, , but don't be in any rush. Give it 3 or more months to occur, as you need flights booked there as evidence, even if you fail.
