Wow saraM!!!
I was sure you are at least in your late 20's because you are so articulate and come across as a very mature person.
Kudos to your parents love, you are sweet, kind, and wise beyond your years!
You are ONLY 19??? just a babyHi there,
I'd go with Tjw25's idea. Working holiday gives you the 12 months together, you apply for the partner (de facto) on the last day of the visa (as many do).
Don't worry about you're age, my partner and I are both 19 (I'm almost 20), and that didn't affect our application at all.
Kudos to your parents love, you are sweet, kind, and wise beyond your years!
