Oh my god hey!!
I'm in Australia too and I make suits!
1) You can either make the suit for yourself (I see that you don't though, but if you want to save money, do it) or you can commission from any other fursuit maker. Just type 'fursuit maker' into google and you're ought to find something that you like! Heck, you can commission from me if you would like (I do do them).
2) You can get fursuit supplies from many places. What supplies are you seeking?
Fur - Spotlight sells fur, however I hate their range as it's pricy and kept in horrible conditions. I buy mine from a small shop called 'My Hung Fabrics'. They have a few other shops around Sydney, if you are interested.
Foam - Clark's Rubber. Other than that, I really don't know. I don't get it from there though. I buy thin camping mattresses and cut them open.
Here is an AWESOME tutorial site.
