Hi Nat!
I'm also looking into moving to Oz - it is scary eh?! I'm also a teacher - so I know that you are going to have a little bit of time to plan, plan, plan over the summer holidays if you're intending to leave later in the summer! There's only so much planning you can do - and you are moving to a country where you can pretty much get everything you need, or sort anything you've forgotten via internet. The best thing about your partner being there first is that he'll be able to tell you what needs doing and what doesn't!
It's an adventure! Enjoy the rest of your time here - you may not be back for a little while and you don't want to regret spending your time worrying before you leave! If you hate it when you get there then you'll figure out what to do then - but you can't worry about it like that in advance, otherwise you're not enjoying your time here. And you won't enjoy time there. At worst - you come home if you don't like it. You know you can get a job and find somewhere to live here - so what's to worry about?!!
Totally normal to feel petrified - but just go with it. Lots of people on here are desperately struggling to move to Oz. This is a great opportunity. So give it a go!
From what I understand, teaching over there is a lot less stressful, but it's hard to find work. However the good thing about going at end of summer is that their academic year starts in January - so it gives you time to put your feelers out for how it works and what's available or even if you want to teach out there.
All the best! And Enjoy!
