UK Spouse Visa Advice

Hi all,

I was wondering if there was any advice out there for us!?! I'm a British citizen living in Australia with my Brazilian husband, we have no kids or dependents. We're looking to move back to the UK due to my dad's poor health and to be closer to family. We satisfy all of the criteria but the Financial Requirements are proving a bit of a headache. I earn 18,600+ here in Australia, as does my husband. We received advice that I need to have a job lined up in the UK earning 18,600 but this is proving difficult, especially as I'm a teacher and face-to-face interviews are the norm for working with young people. We have savings in my husband's name in Brazil and some here in both names. My parents will be accomodating us to begin with, they own their house, have no debts and savings that they'd like us to use to support our application.
My questions are - do we have enough to go on? Can we use the fact that my folks want to help us? We have notarised letters from both my mum and sister about the legitimacy of our relationship and can get a medical certificate proving my dad's condition.
My head is about to explode with all of the info I've read.

Thanks!
