Thanks mate.
Nomination was approved same day as they served me with the letter 08/08/18.
The main things we had to prove were:
-That it would cause significant stress to an Australian resident or citizen if I was to not have my visa approved.
My partner is studying at the moment (she is a citizen) and my baby is obviously a citizen so I am the only breadwinner in the household so that helped. For that we had to supply her TAFE documents, our joint bank account details etc.
- That I had significantly contributed to the Australian economy and communities (member of surf life savers, charities etc)
I am not a member of any charities or clubs (that would of helped) but I do pay a lot of tax so we sent my last 2 years PAYG summaries.
- I had made a genuine mistake.
I had but this was hard to prove. My MA helped write a letter along with the HR manager of my employer to explain my character etc and that I had made a genuine mistake I hadn't tried to hide anything etc.
We also included my mortgage documents to show we owned a home here etc.
Hope this helps!
